<title>Introduction</title>
<p>Currently, the widespread application of digital technology has become a key driver of high-quality economic and social development in rural areas. Digital countryside construction (DCC), a pivotal rural development strategy integral to the &#x201C;digital China&#x201D; and &#x201C;rural revitalization&#x201D; strategies, was initially outlined in the 2018 No. 1 Document, titled <italic>&#x201C;Opinions of the Central Committee of the Communist Party of China and the State Council on Implementing the Rural Revitalization Strategy.&#x201D;</italic> It has not only markedly enhanced rural informatization and intelligent infrastructure but has also significantly impacted industrial structure optimization, social governance innovation, and urban&#x2013;rural integration (<xref ref-type="bibr" rid="ref16">Lei et al., 2023</xref>).</p>
<p>The sports industry, a crucial component of the contemporary service sector, is essential for stimulating economic growth, enhancing public health, and boosting social and cultural vitality (<xref ref-type="bibr" rid="ref56">You and Gao, 2024</xref>). It is closely intertwined with the objectives of rural revitalization&#x2014;including advancements in public services, industrial development, talent cultivation, cultural heritage, ecological protection, and organizational capabilities&#x2014;as highlighted by the General Administration of Sport of China in the <italic>&#x201C;Guiding Opinions on Promoting the Role of Sports in Rural Revitalization&#x201D;</italic> issued in June 2023.</p>
<p>In recent years, the deepening implementation of the rural revitalization strategy has accelerated the process of DCC. Concurrently, the integration of the sports industry through technologies such as big data, artificial intelligence (AI), and the Internet of Things (IoT), creating novel drivers for the development of the rural economy (<xref ref-type="bibr" rid="ref4">Cheng and Wang, 2024</xref>). Specifically, the enhancement of digital infrastructure has notably improved public sports services in rural areas, thereby increasing the convenience and accessibility of sports participation for rural residents (<xref ref-type="bibr" rid="ref17">Li and Gao, 2025</xref>). Furthermore, digital technology has facilitated the integrated development of the sports industry with other sectors such as rural tourism and elderly healthcare, thus expanding the sports consumption market (<xref ref-type="bibr" rid="ref23">Liu, 2025</xref>). Considering this context, it is crucial to decipher the impact of DCC on the development of the sports industry and elucidate the underlying mechanisms that drive this impact. Herein, a benchmark regression model is employed, utilizing provincial-level panel data from China (2013&#x2013;2022), and a fixed-effects model is incorporated to analyze the relationship between DCC and sports industry development. The primary objectives are twofold: (1) to quantitatively analyze the direct impact of DCC on the development of the sports industry, and (2) to explore the potential mechanisms through which DCC influences the sports industry. The findings will provide valuable theoretical and practical insights into leveraging digital strategies to foster the sustainable development of the rural sports industry, thereby enriching existing literature in the fields of digital economy and sports industry development.</p>
<sec id="sec3">
<label>1.1</label>
<title>Literature review</title>
<p>The concept of the <italic>digital countryside</italic> was first introduced in the <italic>Strategic Plan for Rural Revitalization (2018&#x2013;2022)</italic>. As a critical component of China&#x2019;s national rural revitalization strategy, DCC aims to modernize agriculture and rural areas through the application of advanced information technologies, thereby facilitating integrated urban&#x2013;rural development (<xref ref-type="bibr" rid="ref21">Li et al., 2025</xref>). In recent years, a growing body of scholarly research has explored the connotations and extensions of DCC from manifold perspectives.</p>
<p>From an agricultural perspective, existing studies predominantly concentrate on themes including high-quality agricultural development, green transformation, and rural common prosperity. <xref ref-type="bibr" rid="ref50">Wen (2025)</xref> posited that DCC served as a pivotal strategy to foster the high-quality development of the rural economy and to facilitate the deep integration of rural industries. Empirical analysis conducted by <xref ref-type="bibr" rid="ref54">Yang et al. (2025)</xref> and colleagues demonstrated that DCC significantly fostered green agricultural development by reducing energy consumption, diminishing pollution emissions, and enhancing agricultural productivity. Similarly, <xref ref-type="bibr" rid="ref44">Wang (2025)</xref> asserted that DCC was an essential strategy for achieving common prosperity in rural areas. Empowered by information technology, DCC is capable of optimizing agricultural production models, elevating farmers&#x2019; incomes, and narrowing the urban&#x2013;rural development gap.</p>
<p>From a broader perspective, scholars have examined the impact of DCC on urban&#x2013;rural integration and county-level economic development. <xref ref-type="bibr" rid="ref34">Shen and Zheng (2024)</xref> found that DCC significantly promoted high-quality urban&#x2013;rural integration, with market-oriented factor allocation (MFA) serving as a key moderating factor. <xref ref-type="bibr" rid="ref37">Sun et al. (2025)</xref> concluded that within the expansive framework of &#x201C;digital China,&#x201D; DCC had altered the bias of technological progress in county economies&#x2014;shifting toward capital-intensive development with an increasing degree of capital bias.</p>
<p>As an integral segment of the contemporary service economy, the sports industry possess substantial significance in fostering economic growth, enhancing public health, and enriching social and cultural life (<xref ref-type="bibr" rid="ref1">Abrahamyan, 2023</xref>). In recent years, with the implementation of national policies supporting the sports industry, academic research has increasingly concentrated on its development, yielding a wealth of theoretical and empirical findings.</p>
<p>At the theoretical level, studies have explored foundational frameworks, functional mechanisms, and pathways for optimizing the development of the sports industry. <xref ref-type="bibr" rid="ref11">Kang et al. (2024)</xref> emphasized that institutional infrastructure constituted the foundational framework for the effective functioning of the sports industry, arguing for the importance of top-level design in establishing a mutually reinforcing system. <xref ref-type="bibr" rid="ref61">Zhang and Wang (2021)</xref> identified factor supply and market demand as the dual endogenous driving forces essential for the high-quality development of the sports industry. <xref ref-type="bibr" rid="ref52">Xu et al. (2019)</xref> and colleagues believed that the essence of high-quality development of the sports industry lay in the expansion of the sports program sector, innovation in content, and the breaking of traditional development constraints.</p>
<p>At the empirical level, scholars have examined relevant themes such as industrial synergy and structural transformation. As the sports industry evolves toward greater integration and intelligence, new patterns have emerged. For example, <xref ref-type="bibr" rid="ref20">Li et al. (2023)</xref> discovered that the integration of the digital economy and the sports industry demonstrated a strong and growing degree of coupling coordination, evolving from fragile to robust levels. <xref ref-type="bibr" rid="ref64">Zheng et al. (2023)</xref> highlighted the challenges facing the development of AI-empowered sports, including the digital DCCide, limited mastery of core technologies, and insufficient high-level talent.</p>
<p>As a vital component of the rural revitalization strategy, DCC utilizes information technology to stimulate rural development by enhancing digital infrastructure and facilitating the digital transformation of agriculture. In this context, the sports industry contributes to upgrading rural industrial structures by fostering rural outdoor sports, folk sports events, and recreational programs, thereby transforming ecological resources into distinctive local industries.</p>
<p>On one hand, research on the integration of DCC with the sports sector remains limited. <xref ref-type="bibr" rid="ref22">Liang (2024)</xref> demonstrated that DCC significantly promoted the development of rural sports tourism by analyzing its underlying mechanisms, with seven key mechanisms identified, including the construction of informatization infrastructure and the enhancement of digital services. Similarly, <xref ref-type="bibr" rid="ref8">Gao et al. (2024)</xref> and colleagues posited that the theory of holistic governance accurately aligned with the value logic of providing public services for national fitness in rural areas.</p>
<p>On the other hand, in the realm of rural revitalization and the integration of the sports industry, researchers have uncovered a variety of valuable insights. <xref ref-type="bibr" rid="ref26">Lu et al. (2024)</xref> and co-authors proposed that to address the current challenges faced by the rural sports industry, emphasis should be placed on ecological transformation, innovation in resource structures, and enhancing resilience for high-quality development. <xref ref-type="bibr" rid="ref44">Wang (2025)</xref> and colleagues discovered a significant positive spatial correlation between the coupling coordination level of the sports industry and rural revitalization, exhibiting clear spatial clustering characteristics.</p>
<p>Nevertheless, a significant academic gap persists regarding the intersection of DCC and sports integration. The present study aims to explore the mechanisms through which DCC influences the development of the sports industry, which would offer meaningful scholarly value.</p>
<p>Collectively, existing research primarily investigated the relationship between digital technology and industrial development from two key perspectives: Firstly, studies on DCC have employed quantitative methods to verify its macro-level contributions to rural economic growth and household consumption. Secondly, research on the sports industry has predominantly concentrated on the impact of specific factors&#x2014;such as the digital economy and digital finance&#x2014;on the transformation and upgrading of the sector. However, despite these studies offering important theoretical foundations, a significant research gap remains: few have systematically examined how comprehensive DCC&#x2014;as a holistic strategy&#x2014;affects the development of the rural sports industry through specific mechanisms. This study seeks to bridge the existing gap by developing an empirical model to elucidate the intrinsic causal relationship between DCC and the sports industry.</p>
<p>Compared to previous studies, the contributions of the present study are threefold: (1) it examines the theoretical relationship between DCC and the development of the sports industry, thus expanding the literature in this field; (2) it incorporates MFA and rural consumption upgrade (RCU) as mediating and moderating variables to explore the inherent mechanisms using appropriate econometric models, thereby contributing novel perspectives to the development of the sports industry; and (3) it investigates regional heterogeneity to assess inter-city differences in the relationship between DCC and sports industry development, offering rational explanations based on regional disparities.</p>

<label>2.1</label>
<title>The impact of DCC on the development of the sports industry</title>
<p>As a key component of China&#x2019;s rural revitalization strategy, the core objective of DCC is to drive the modernization and transformation of sectors such as agriculture, culture, education, and healthcare through the integration of digital technologies. In recent years, the Chinese government has introduced a series of supportive policies to facilitate DCC and encourage the application of digital technologies to upgrade rural industries.</p>
<p>In this context, the sports industry&#x2014;an essential driver of rural economic development and a contributor to enhancing residents&#x2019; quality of life&#x2014;has been significantly influenced by DCC. Specifically, DCC has enhanced the informatization level of rural sports infrastructure. Technologies such as IoT, big data, and AI have enabled intelligent management of rural sports facilities, thereby enhancing their utilization rates (<xref ref-type="bibr" rid="ref62">Zhao X. et al., 2024</xref>; <xref ref-type="bibr" rid="ref63">Zhao Y. et al., 2024</xref>). Systems for online reservations, intelligent monitoring, and digital operations have optimized the allocation of sports resources, reduced venue idleness, and reinforced the capacity of rural public sports services. Moreover, digital technologies have facilitated the market-oriented development of the rural sports industry. The emergence of e-commerce and short-video platforms has created new marketing and promotional avenues for rural sports tourism, training programs, and event hosting (<xref ref-type="bibr" rid="ref62">Zhao X. et al., 2024</xref>; <xref ref-type="bibr" rid="ref63">Zhao Y. et al., 2024</xref>). Through the integration of &#x201C;Internet + Sports,&#x201D; rural programs&#x2014;including traditional ethnic sports, outdoor adventures, and grassroots competitions such as &#x201C;Rural BA&#x201D; and &#x201C;Rural Super&#x201D;&#x2014;have been able to overcome geographical constraints and attract a extensive consumer base. These have contributed to the expansion of the rural sports tourism and event markets, extending the value chain of the sports industry (<xref ref-type="bibr" rid="ref38">Tan and Bu, 2025</xref>).</p>
<p>Moreover, DCC has transformed the sports consumption behavior of rural residents. The prevalence of smart devices has facilitated convenient access to fitness content, while services such as remote coaching and online classes have increased sports participation. These changes have not only stimulated rural demand for sports consumption but also prompted the sports industry to optimize its supply structure to meet the DCCerse and personalized market needs (<xref ref-type="bibr" rid="ref59">Zhang and Dong, 2024</xref>). Based on the above analysis, the following research hypothesis is proposed:</p>
<disp-quote>
<p><italic>H1</italic>: DCC exerts a significant positive impact on the development of the sports industry.</p>
</disp-quote>
</sec>
<sec id="sec6">
<label>2.2</label>
<title>The regulating role of market-oriented factor allocation (MFA)</title>
<p>Digital technologies have significantly enhanced the allocation efficiency of key production factors&#x2014;such as capital, technology, and labor&#x2014;by reshaping the pathways of factor circulation and redefining value creation models. They also assist in overcoming traditional barriers of time, space, and information asymmetry within factor markets (<xref ref-type="bibr" rid="ref58">Zhang et al., 2025</xref>).</p>
<p>Firstly, in the context of DCC, technologies such as big data, remote sensing, and blockchain are applied to land information management systems, enhancing the scientific planning and utilization of rural sports infrastructure. This alleviates issues of idle land and inefficiency, optimizes the structure of land resource allocation, and revitalizes the market for land use in rural sports development (<xref ref-type="bibr" rid="ref6">Fan and Kang, 2023</xref>).</p>
<p>Secondly, the rural sports industry has historically suffered from limited financing channels and long capital return cycles. The advent of digital finance has offered solutions by expanding funding sources. Progressive digital tools&#x2014;such as inclusive finance, crowdfunding models, and blockchain-enabled risk control mechanisms based on big data&#x2014;have provided the rural sports industry with increased social capital, improved capital allocation efficiency, and reduced investment risks, thereby fostering its market-oriented development (<xref ref-type="bibr" rid="ref29">QI et al., 2020)</xref>.</p>
<p>Thirdly, DCC has also promoted the optimal allocation of human resources within the sports industry. Supported by digital tools such as distance education and online training platforms, rural residents are able to access more professional instruction, which enhances the overall skill level of practitioners in the rural sports industry (<xref ref-type="bibr" rid="ref47">Wang and Wu, 2024</xref>). Furthermore, the establishment of digital employment platforms helps to overcome geographic barriers, enabling professional sports talents to accurately meet rural demands, thus optimizing the human resources structure and spurring industry competitiveness. Based on the above analysis, the following hypothesis is proposed:</p>
<disp-quote>
<p><italic>H2</italic>: MFA exerts a positive moderating effect on the relationship between DCC and the development of the sports industry.</p>
</disp-quote>
</sec>
<sec id="sec7">
<label>2.3</label>
<title>The mediating role of rural consumption upgrade (RCU)</title>
<p>DCC serves not only as a strategic path for rural revitalization but also as a key catalyst for RCU (<xref ref-type="bibr" rid="ref48">Wang et al., 2021</xref>). It enhances digital infrastructure, improves information flow, and raises residents&#x2019; income levels, thereby effectively stimulating the consumption demand and promoting the expansion and upgrade of the rural sports industry.</p>
<p>On one hand, advancements of information and communication technologies have narrowed the digital DCCide between urban and rural areas. Consequently, rural production and lifestyles have been significantly altered by enhanced information infrastructure, optimized factor allocation, and expanded agricultural product circulation channels. This, in turn, enhances the digital literacy and consumption capacity of farmers, stimulates rural domestic demand, and reshapes the rural consumption structure&#x2014;from subsistence-level consumption to development-oriented and enjoyment-oriented consumption. These alterations offer robust technological and institutional support for RCU (<xref ref-type="bibr" rid="ref3">Bi and Chu, 2025</xref>).</p>
<p>On the other hand, RCU is accompanied by increased health consciousness and transformed residential lifestyles, which results in a growing, DCCerse, and multi-level demand for sports consumption. The rising demand for physical fitness, leisure, and recreation services in rural areas has spurred the expansion of the sports industry, enriching its product offerings and services. Against the backdrop of urban&#x2013;rural integration, this trend fosters the extension of sports resources to grassroots communities and hastens the optimization of the sports industry&#x2019;s spatial distribution, service models, and value chains. Consequently, RCU has emerged as a crucial driver in fostering the coordinated development of regional economies and enhancing national physical fitness (<xref ref-type="bibr" rid="ref43">Wan and Wang, 2024</xref>). Based on the above analysis, the following hypothesis is proposed:</p>
<disp-quote>
<p><italic>H3</italic>: DCC indirectly fosters the development of the sports industry through RCU.</p>
</disp-quote>
<p>In summary, according to the research hypothesis of this paper, the model path diagram of H1-H3 is constructed. As shown in <xref ref-type="fig" rid="fig1">Figure 1</xref> below.</p>

<title>Core explanatory variable: digital countryside construction(DCC)</title>
<p>The core explanatory variable is DCC, which refers to a systematic development strategy that utilizes modern information technologies&#x2014;such as big data, the Internet, and AI&#x2014;to drive rural revitalization by bridging the digital divide between urban and rural areas and enhancing digital infrastructure, services, and industries. Herein, the measurement framework developed by <xref ref-type="bibr" rid="ref57">Yu et al. (2025)</xref> and others was employed, where DCC was evaluated across four dimensions: digital capital investment, digital information infrastructure, digital service level, and digital industry development. All indicators within these dimensions are endowed with appropriate weights using the entropy method to ensure objective evaluation.</p>
</sec>
<sec id="sec12">
<label>3.1.3</label>
<title>Moderating variable: market-oriented factor allocation(MFA)</title>
<p>The moderating variable is MFA, which represents the process by which capital, labor, and technology are allocated through market mechanisms, allowing production factors to flow efficiently to areas with the highest marginal productivity. It enhances resource optimization, stimulates economic vitality, supports high-quality industrial development, and reflects a transition from direct government intervention to institutional regulation and environment-building. Herein, the MFA measuring approach proposed by Marin (2024) was utilized, which encompassed three dimensions: labor market allocation, capital market allocation, and technology market allocation. The entropy method was used to derive appropriate weights for these indicators.</p>
</sec>
<sec id="sec13">
<label>3.1.4</label>
<title>Mediating variable: rural consumption upgrade (RCU)</title>
<p>The mediating variable is RCU, which reflects the transformation in rural residents&#x2019; consumption behavior in response to elevated income levels and improved quality-of-life aspirations. As the disposable income of rural residents increases, their consumption patterns have shifted from satisfying fundamental necessities to purchasing developmental, recreational, and health-related goods and services. Following <xref ref-type="bibr" rid="ref54">Yang et al. (2025)</xref>, the per capita consumption expenditure of rural residents was used as a proxy indicator for RCU.</p>
</sec>
<sec id="sec14">
<label>3.1.5</label>
<title>Control variables</title>
<p>To ensure a more accurate assessment of the relationship between DCC and the development of the sports industry, control variables should be introduced to account for confounding factors that may exert potential impact. Building upon the research endeavors of previous scholars, five control variables that may affect the development of the sports industry were identified: (1) Government intervention (Gov), as adopted by Bidayu (2025), is represented by the ratio of general public budget revenue to general public expenditure; (2) The level of financial development (Fin), as used by <xref ref-type="bibr" rid="ref54">Yang et al. (2025)</xref> and others, is measured as the ratio of total deposits and loans of regional financial institutions to the region&#x2019;s gross domestic product (GDP); (3) The investment capacity of rural households (Fic), as referenced by Yu, (2024), is measured by per capita fixed asset investment by rural households; (4) The governance level of rural roads (Roa), as utilized by <xref ref-type="bibr" rid="ref41">Tian et al. (2024)</xref>, is calculated as ((\text{total road mileage}&#x202F;&#x2212;&#x202F;\text{highway mileage}&#x202F;&#x2212;&#x202F;\text{first-class highway mileage}) / \text{provincial land area})&#x202F;&#x00D7;&#x202F;100; (5) Education level (Edu), as employed by <xref ref-type="bibr" rid="ref23">Liu (2025)</xref>, is measured by the number of high school students per 100,000 people.</p>

<title>Data sources</title>
<p>Given the late development of the sports industry in certain provinces and incomplete data availability, most provincial-level administrative regions only began publishing official statistics in 2015. To ensure data authenticity, scientific reliability, and quality control, these provinces and corresponding years were excluded from the analysis. This study selects 21 provincial-level administrative regions in China (Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, Liaoning, Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Shandong, Henan, Hubei, Hunan, Guangdong, Chongqing, Sichuan, Guizhou, and Yunnan) for panel data analysis spanning 2015&#x2013;2023. The dataset comprises 189 samples, with missing values addressed through interpolation. Data were sourced from the Sports Bureaus of each province, the National Bureau of Statistics, the official website of the General Administration of Sport of China, the China Statistical Yearbook, the China Rural Statistical Yearbook, the China Taobao Rural Research Report, and the China Research Data Service Platform (CNRDS). Rural e-commerce activity is measured using provincial-level indicators, while the digital financial inclusion index is derived from the Peking University Digital Financial Inclusion Index.</p>

<p>Descriptive statistical analysis was initially conducted to clarify the variation characteristics of each variable and achieve a more comprehensive understanding of the samples&#x2019; development patterns. To mitigate potential heteroskedasticity in empirical regression, natural logarithmic transformation was applied to the following variables: financial development, rural household investment capacity, rural road governance level, education level, and RCU. As shown in <xref ref-type="table" rid="tab3">Table 3</xref>, the mean and standard deviation for DCC were 0.1122 and 0.0963, respectively, whereas those for the sports industry were 0.1182 and 0.0943. These values suggest a relatively low variability and a concentrated distribution across samples. Subsequent analysis of the standard deviation, maximum, and minimum values for other variables reveals considerable variations in financial development, rural investment capacity, and road governance levels across different provinces. Regional disparities in economic policy, geographic coverage, and resource endowments likely explain these discrepancies.</p>

<p>Model <italic>Sic</italic> (1) presents the baseline regression without control variables. Model <italic>Sic</italic> (2) includes control variables but omits fixed effects, while Model <italic>Sic</italic> (3) incorporates both control variables and regional and temporal fixed effects. In all three models, the regression coefficients for digital countryside construction (DCC) are 0.3359, 0.3791, and 0.3129, respectively&#x2014;all of which are positive and statistically significant at the 1% level. This suggests that digital countryside construction significantly promotes the development of the sports industry.</p>
<p>The regression results in <xref ref-type="table" rid="tab4">Table 4</xref> indicated that enhanced digital infrastructure provided an essential foundation for connecting rural sports resources. The proliferation of online platforms and social media has reduced promotional costs, broadened market access for rural sports brands, and enhanced accessibility and participation in sports consumption for rural residents (<xref ref-type="bibr" rid="ref7">Fu, 2024</xref>). Meanwhile, digital governance tools have assisted planning and performance assessment, enabling governments to adjust policies based on real-time data. This further enhances investment efficiency and fosters cross-sector integration through initiatives such as &#x201C;Internet + Sports + Tourism&#x201D; and &#x201C;E-commerce + Rural Sports Equipment (<xref ref-type="bibr" rid="ref58">Zhang et al., 2025</xref>).&#x201D; This multi-dimensional integration, centered on sports events, drives the coordinated development of related sectors such as leisure, recreation, and tourism (<xref ref-type="bibr" rid="ref58">Zhang et al., 2025</xref>).</p>
<p>However, there remains a paucity of research on the nexus between DCC and the growth of the sports industry in China. International literature suggests that the digital economy plays a significant role in facilitating the expansion of scale and diversification of services within the urban sports industry by enhancing resource allocation efficiency and reducing information asymmetry (<xref ref-type="bibr" rid="ref18">Li and Han, 2023</xref>; <xref ref-type="bibr" rid="ref14">Krishna et al., 2024</xref>). This study further indicates that such a mechanism may also be operative in rural contexts. Particularly against the backdrop of a national strategic emphasis on synergistically advancing &#x201C;digital villages&#x201D; and &#x201C;mass fitness,&#x201D; the catalytic role of digitalization in promoting the rural sports industry assumes heightened policy relevance and practical significance.</p>
<p>Regarding the control variables, Models <italic>Sic</italic> (2) and <italic>Sic</italic> (3) provide the following insights: Government intervention exhibits negative coefficients of &#x2212;0.0479 and &#x2212;0.1031, respectively. While not significant without fixed effects, the coefficient becomes significant at the 10% level when fixed effects are included, indicating that structural differences across regions and time periods highlight the negative influence of government intervention. Financial development shows positive coefficients of 0.0275 and 0.0411, both significant at the 1% level, suggesting that financial advancement supports optimized capital allocation, DCCersified financing, and reduced costs, thereby facilitating investment and innovation in the sports industry. The investment capacity of rural households also has a significant positive impact, indicating that increased capital supports infrastructure development and boosts local sports consumption, thus stimulating the synergistic growth of the sports industry chain (<xref ref-type="bibr" rid="ref25">Liu et al., 2024</xref>). However, road governance and education levels do not exhibit statistically significant effects in this analysis, implying their influence may be limited or overshadowed by more dominant factors within this economic structure.</p>

<title>Endogeneity test</title>
<sec id="sec21">
<label>4.3.1</label>
<title>Endogeneity test</title>
<p>When assessing the impact of DCC on the development of the sports industry, two potential key sources of endogeneity arise. The first is the omitted variable bias, where unobservable factors&#x2014;such as local policy initiatives or regional cultural attributes&#x2014;might simultaneously influence the development of both the digital infrastructure and the sports industry growth, leading to biased regression estimates. The second is the issue of reverse causality: digital technologies promote the dissemination and interactivity of sports events, thereby fostering the development of the sports industry. Consequently, the growth of the sports industry may further drive the innovation and application of digital technologies in rural construction. This dynamic, bidirectional relationship complicates the establishment of a clear causal order, reflecting a mutually reinforcing feedback loop between technological innovation and industrial development.</p>
<p>To address this endogeneity problem, this study uses the lagged one-period value of digital countryside construction (DCC-IV) as an instrumental variable. The results from the two-stage least squares (2SLS) regression are presented in <xref ref-type="table" rid="tab5">Table 5</xref>. In the first stage, the F-statistic of 74.19 indicates that the instrumental variable has strong explanatory power for the endogenous regressor. Furthermore, the Cragg-Donald Wald F-statistic exceeds the 10% Stock-Yogo critical threshold of 16.38, confirming the absence of a weak instrument problem. In the second stage, the estimated coefficients remain positive and statistically significant at the 1% level, consistent with the baseline model results. These findings validate the robustness of the study&#x2019;s conclusions and affirm the significant positive impact of digital countryside construction on the development of the sports industry.</p>

As illustrated in <xref ref-type="table" rid="tab7">Table 7</xref>, the interaction terms remained significantly positive at the 10% level, suggesting that factor marketization exert a positive moderating effect. This demonstrates that MFA enhances the positive effect of DCC on the development of the sports industry.</p>

<p>Specifically, MFA enhances the mobility and allocation of market resources, such as land, labor, and capital, thereby boosting the efficiency of resource distribution. This forges a robust institutional and economic foundation for the integration of digital technologies in rural areas (<xref ref-type="bibr" rid="ref24">Liu et al., 2025</xref>). Furthermore, market-oriented reforms increase the adaptability and responsiveness of the sports industry to the requirements of DCC. Factor-efficient markets also help reduce systemic transaction costs, incentivize private capital to engage in the rural sports sector, and support the upgrading of the sports product supply structure and service quality (<xref ref-type="bibr" rid="ref27">Ma and Huang, 2024</xref>). Consequently, MFA not only strengthens the economic foundations of DCC but also fosters the high-quality development of the sports industry.</p>

<title>Mediating effect analysis of RCU</title>
<p>Mediating effect analysis investigates the mechanism through which an independent variable indirectly affects a dependent variable via a mediating variable, thereby deepening the understanding of the internal relationship among variables. Herein, the mediating role of RCU in the relationship between DCC and the development of the sports industry was examined using a three-stage regression analysis, as described by <xref ref-type="disp-formula" rid="EQ9 EQ10 EQ11">Equations 9&#x2013;11</xref>. As depicted in <xref ref-type="table" rid="tab8">Table 8</xref>, the regression coefficients of DCC in models <italic>Sic</italic> (9) and <italic>Sic</italic> (10), as well as the regression coefficients of RCU in models Rc (1) and <italic>Sic</italic> (10), all exhibited significantly positive values. This indicates that DCC exerts a significant positive effect not only on RCU but also on the development of the sports industry. Moreover, the regression coefficient of DCC decreased from 0.3129 in <italic>Sic</italic> (9) to 0.2959 in <italic>Sic</italic> (10) upon the inclusion of the mediating variable, suggesting the a partial mediating effect. This confirms that DCC fosters the development of the sports industry in part through the pathway of RCU.</p>

<p>Specifically, the deep integration of digital technologies in rural areas has improved information access, gradually reshaped consumption attitudes, and markedly enhanced the awareness of sports consumption among rural residents. Consequently, rural residents have shifted their survival-oriented consumption pattern to one that is developmental and enjoyment-based (<xref ref-type="bibr" rid="ref53">Yang and Li, 2025</xref>). Furthermore, digital technologies have improved the accessibility and convenience of sports products and services, broadened the market reach of the sports industry, and reinforced the role of RCU in driving and supporting the growth of the sports industry. Therefore, DCC indirectly facilitates the high-quality development of the sports industry.</p>

This finding confirms that the market-oriented allocation of factors has a positive moderating effect on the relationship between digital countryside construction and the sports industry. In summary, the study elucidates both the direct and indirect pathways through which digital countryside construction promotes the development of the sports industry, while highlighting the synergistic effects of rural consumption upgrading and the market-oriented institutional environment. Accordingly, the research hypotheses H1, H2, and H3 are further validated through PLS-SEM analysis.</p>

<title>Heterogeneity analysis</title>
<p>Given the substantial variations in natural conditions, economic resources, and development levels across different regions in China, a heterogeneity analysis was subsequently conducted, focusing on the regional divisions established by the National Bureau of Statistics. To examine the differential impact of DCC on the development of the sports industry across the entire country, the samples were classified into three primary regions: eastern China (including Beijing, Tianjin, Hebei, Liaoning, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong, and Guangdong), central China (including Shanxi, Inner Mongolia, Anhui, Jiangxi, Henan, Hubei, and Hunan), and western China (including Chongqing, Sichuan, Guizhou, and Yunnan).</p>
<p>As shown in <xref ref-type="table" rid="tab11">Table 11</xref>, the impact of DCC on the development of the sports industry exhibited pronounced regional heterogeneity. The regression results demonstrated a significant positive effect in eastern China, a negative but statistically insignificant effect in central China, and a positive but also insignificant effect in western China. These disparities can be attributed to structural differences among different regions, including economic foundations, digital infrastructure, stages of sports industry development, and policy support.</p>

<p>Eastern China is characterized by a higher level of economic development, greater penetration of digital technology, and deeper urban&#x2013;rural integration, thereby offering a favorable market environment and technological support for the growth of the sports industry.</p>
<p>In central China, the impact of DCC on sports industry development has been relatively limited. The reasons are twofold: Firstly, compared to eastern China, the central region may experience delays in policy coordination between DCC and sports industry development. Certain policies have not successfully integrated digital technologies into the local sports industry development plans, preventing policy benefits from creating synergies and impeding industrial advancement. Secondly, residents in central China may still favor traditional sports consumption habits, exhibiting relatively lower acceptance of digital sports services. Despite established digital infrastructure, the inertia of consumer preferences and habits hinders the potential simulative effect of digital technologies on sports consumption.</p>
<p>Regarding western China, the impact of DCC on sports industry development is minimal, or even negative, likely due to the following reasons: Firstly, considering the limited public resources in western China, substantial investments on digital infrastructure could temporarily divert critical resources from other sectors crucial to sports industry development, causing the &#x201C;crowding-out effect&#x201D; of infrastructure investments. This trade-off dynamic may explain why initial investments in DCC have failed to yield the anticipated positive effects. Secondly, given the significant geographical constraints, educational disparities, and digital literacy gaps in western China, it would take considerable time for the implementation of DCC to bridge the ever-expanding digital divide between urban and rural residents. Thirdly, compared to the eastern and central regions of China, the sports industry in the western part is underdeveloped, characterized by a low level of marketization and incomplete industrial chains. In this context, digital technology alone may find it challenging to generate a significant impact.</p>

<title>Conclusion</title>
<p>Herein, the impact of DCC on the development of the sports industry was investigated utilizing panel data from 21 provinces in China spanning from 2015 to 2023. Through the application of fixed effects models, moderating effect models, and mediating effect models, the mechanisms and pathways by which DCC influences sports industry development were comprehensively examined. The following conclusions can be drawn:</p>
<p>The present study offers significant theoretical contributions to the existing literature in the fields of digital economy and industrial development. Firstly, it systematically explored the intrinsic logical relationship between comprehensive DCC and sports industry development, bridging a research gap in this field. Unlike previous studies that have concentrated on individual components such as the digital economy or digital finance (<xref ref-type="bibr" rid="ref5">Deng and Li, 2023</xref>), the present study approached DCC as a comprehensive strategy, revealing its multifaceted impact on the development of a particular industry. Secondly, by constructing moderation and mediation models, the present study made the first attempt to quantify the transmission mechanisms of MFA and RCU within this influence chain, deepening the understanding of how digital strategies drive industrial development. Thirdly, the heterogeneity analysis not only confirmed the regionally varied impact of DCC on sports industry development but also offered preliminary theoretical insights into why this impact was less pronounced in central and western China, forging a hypothesis foundation for future in-depth regional studies.</p>
<p>The findings provide essential practical insights for the synergistic advancement of DCC and sports industry development. Firstly, policy coordination and the enhancement of &#x201C;software investments&#x201D; should be strengthened. The driving impact of DCC on the development of the sports industry does not merely stem from &#x201C;hardware investments,&#x201D; such as those in digital infrastructure, but rather involves &#x201C;software investments,&#x201D; which warrant greater emphasis. For instance, policy guidance and financial support should be introduced to encourage the development of digital sports service platforms and innovative, market-oriented operational mechanisms. This will help ensure that digital accomplishments are effectively translated into key drivers of industrial development (<xref ref-type="bibr" rid="ref55">Ye and Chen, 2023</xref>). Secondly, region-specific development strategies and measures, tailored to local conditions, should be implemented. The heterogeneity analysis presented herein revealed the distinct responses to DCC across different regions, suggesting that provincial governments should implement differentiated development strategies rather than adopting a one-size-fits-all approach. Furthermore, market entities should be encouraged to actively engage in digital transformation (<xref ref-type="bibr" rid="ref45">Wang and Huang, 2025</xref>). Specifically, within the sports industry, sports companies and other relevant market participants should take the initiative to embrace digital transformation. This will enable market entities to capitalize on opportunities presented by DCC, explore novel business models, and identify promising growth areas.</p>
<p>The findings of the present study hold significant practical and theoretical implications, not only for China but also offering valuable insights for other nations navigating digital transformation and sports industry development. Many countries, especially those that are developing, encounter similar challenges in advancing digital transformation, particularly in ensuring that &#x201C;hardware investments&#x201D; effectively translate into &#x201C;soft drivers&#x201D; for industrial growth. For instance, India is actively promoting its &#x201C;digital India&#x201D; strategy to increase the penetration of information technology in rural areas; however, the development of its sports industry is hindered by bottlenecks in funding, talent, and business model innovation (<xref ref-type="bibr" rid="ref35">Singh and Nimkar, 2020</xref>). Similarly, Brazil is accelerating internet access in rural regions, yet its sports industry heavily depends on major events, such as soccer, and is deficient of effective integration with the local digital technology ecosystem (<xref ref-type="bibr" rid="ref9">Hall and Nicholas, 2019</xref>). In contrast, China possesses exceptional advantages in terms of top-level design and policy coordination. Its DCC strategy facilitates systematic planning across multiple dimensions: infrastructure, digital services, and industrial development; however, China still faces challenges associated with regional heterogeneity and policy implementation, as revealed herein. These findings offer valuable insights for other countries developing comparable strategies.</p>

<title>Research limitations and future directions</title>
<p>The present study sheds lights on the relationship between DCC and the development of the sports industry. However, limitations persist in several aspects, including reliance on macro-level data, the construction of indicator system, and potential endogeneity issues. Specifically, due to the use of provincial-level panel data, the present study does not capture detailed impact mechanisms at the municipal, county, or micro-level entities (<xref ref-type="bibr" rid="ref28">&#x00D6;zmen et al., 2016</xref>). Additionally, limitations within official statistical definitions and data availability may have excluded certain emerging or informal business models from the evaluation framework (<xref ref-type="bibr" rid="ref15">Kropat et al., 2017</xref>; <xref ref-type="bibr" rid="ref39">Taylan et al., 2010</xref>; <xref ref-type="bibr" rid="ref33">Semih et al., 2022</xref>). While econometric methods were employed to account for these factors, the potential bidirectional causal relationship between them warrants further validation through more sophisticated models in future research.</p>
<p>To address these limitations, future research endeavors can be made in the following directions: Firstly, employing finer-grained microdata could enable deeper exploration of the specific impact mechanisms of DCC at the enterprise and household levels (<xref ref-type="bibr" rid="ref31">Roy and Bhaumik, 2018</xref>; <xref ref-type="bibr" rid="ref2">Babaee et al., 2021</xref>). Secondly, incorporating additional potential mediating and moderating variables&#x2014;such as talent, finance, and cultural factors&#x2014;could reveal more comprehensive impact pathways (<xref ref-type="bibr" rid="ref32">Savku, 2023</xref>). Ultimately, cross-national comparative analysis should be conducted to examine the universality and differences concerning the impact of digital strategies on sports industry development across diverse institutional and cultural contexts, thereby providing more universally applicable theoretical guidance for global policy formulation.</p>
