数字金融、网络中心性与区域创新水平——基于2011-2020年省级面板数据的实证分析

Digital Finance,Network Centrality and Regional Innovation Level:Empirical Analysis Based on Provincial Panel Data from 2011 to 2020

数字金融是实现创新驱动发展,构建现代化经济体系的重要引擎。但数字金融发展仍存在区域不平衡问题。基于社会网络理论分析了数字金融对区域创新水平的促进作用以及网络中心性的调节效应,并使用我国2011—2020年省级平衡面板数据进行了实证检验。研究发现:(1)数字金融有利于提高区域创新水平;(2)数字金融网络中心性对其促进区域创新的效果存在正向调节作用;(3)数字金融网络中心性的调节效应体现出区域差异,处在经纪人板块以及数字金融发展水平更高的地区,网络中心性的正向调节效应更显著,而在资源溢出板块则表现为负向调节效应。研究对于完善数字金融差序发展格局,实现数字金融的创新激励功能具有积极意义。

Digital finance is an important engine for innovation-driven development and building a modern economic system.However,there are still regional imbalances in the development of digital finance.Based on social network theory,this paper analyzes the promotion effect of digital finance on regional innovation level and the moderating effect of network centrality,and conducts an empirical test using provincial balanced panel data from 2011 to 2020 in China.The study found that:(1)digital finance is conducive to improving the level of regional innovation;(2)the centrality of digital financial network has a positive moderating effect on promoting regional innovation;(3)the moderating effect of the centrality of digital financial network reflects regional differences.In areas in the position of“brokers”and areas with a higher level of digital finance development,the positive moderating effect of network centrality is more significant;while in the resource spillover sector,it shows a negative moderating effect.This paper has positive significance for improving the differential development pattern of digital finance and realizing the innovation incentive function of digital finance.
