数字技术赋能公共体育服务发展效应的实证检验

An Empirical Test on Effect of Digital Technique Empowering the Development of Public Sports Service

数字技术是新质生产力赋能公共体育服务发展的关键力量和重要体现。基于2014—2020年中国30个省(区、市)(不含香港地区、澳门地区、台湾地区、西藏)的面板数据,运用双向固定效应模型、动态门槛回归模型,实证分析数字技术、政府治理能力和公共体育服务发展三者间的关系。发现:(1)在直接效应上,数字技术对公共体育服务发展具有显著的正向促进作用,且考虑内生变量和稳健性检验后结论依然成立;(2)在门槛效应上,随着数字技术的进步,数字技术对公共体育服务发展呈现边际效应递减的显著正向影响;(3)在区域异质性上,相较于其他地区,研究时间、区间内数字技术对西部地区公共体育服务发展的影响效应更明显;(4)在中介效应上,提升政府治理能力是数字技术对公共体育服务发展影响效应的重要作用机制。基于此,对未来中国不同区域如何更好地促进数字技术与公共体育服务深度融合、推动公共体育服务的高质量发展提出相关政策建议。

Digital technique is the key force and important embodiment of new productivity to empower public sports service.Based on the data from 2014 to 2020 across 30 China provinces(excluding Hong Kong region,Macao region,Taiwan region,and Xizang),a two-way fixed effects model and a dynamic threshold regression model are employed to empirically examine the relationship among the digital technique,government governance ability and the development of public sports service.It is found that,from direct effect verification,the digital technique has a significantly positive effect on the development of public sports service,and the conclusion is still valid after taking endogenous variables and robustness tests into account.And the threshold effect shows that the digital technique significantly and positively promotes public sports service with marginal diminishing effect.Additionally,from a regional perspective,the digital technique has a more pronounced promoting effect on public sports service development in the western regions compared to the other regions.The verification of intermediary effect shows that improving government governance capability is an important mechanism for the influence of digital technique on the development of public sports service.Feasible suggestions are hence proposed for promoting the deep integration of the digital technique and public sports service,and advancing the high-quality development of public sports service across different regions of China.
