数字经济对基本公共服务均等化的影响及其作用机制研究

The Impact of Digital Economy on Equalization of Basic Public Services and its Mechanism

数字经济深度融合于公共服务体系,对基本公共服务普惠均等有重要影响。本文基于2011—2020年省级面板数据,实证分析数字经济对基本公共服务均等化的影响及作用机制。研究表明,数字经济能够显著提升基本公共服务均等化水平,行政成本是数字经济发挥对基本公共服务均等化正向影响的中介作用路径。进一步研究发现,城镇化在数字经济赋能基本公共服务均等化中具有负向调节作用。将城镇化作为门槛变量进行门槛效应分析发现,数字经济对基本公共服务均等化的促进效应呈现出边际递减的趋势,即随着城镇化推进,数字经济对基本公共服务均等化的正向效应逐渐减弱,当城镇化水平跨越第二个门槛值时,数字经济会降低基本公共服务均等化水平。此外,异质性分析表明,数字经济对基本公共服务均等化的影响在中—西—东部地区呈现出边际递减的趋势,在“宽带中国”战略实施后更为显著。本文为数字经济赋能公共服务均等化,优化数字政府建设,推进基本公共服务均等化进程提供学理支持与实践依据。

The deep integration of the digital economy into the public service system has an important impact on the equality of basic public services.Based on the provincial panel data from 2011 to 2020 in China,this paper empirically analyzes the impact and mechanism of digital economy on the equalization of basic public services.The research shows that digital economy can significantly improve the level of equalization of basic public services,and administrative cost is the intermediary path for digital economy to play a positive effect on equalization of basic public services.Further research finds that urbanization has a negative regulating effect on the equalization of basic public services enabled by the digital economy.Taking urbanization as a threshold variable,the threshold effect analysis found that the promoting effect of digital economy on the equalization of basic public services showed a marginal decreasing trend.With the advancement of urbanization,the positive effect of digital economy on the equalization of basic public services gradually weakened,and when the urbanization level crossed the second threshold,the digital economy would reduce the equalization level of basic public services.In addition,heterogeneity analysis shows that the impact of digital economy on the equalization of basic public services shows a marginal decreasing trend in the central-western-eastern regions,and is more significant after the implementation of the"Broadband China"strategy.This paper provides theoretical support and practical basis for enabling the equalization of public services in digital economy,optimizing the construction of digital government and promoting the equalization of basic public services.
