融通创新对数字经济与绿色经济协同水平的驱动效应——基于粤港澳大湾区的实证分析

Driving Effect of Integrated Innovation on Synergistic Level of Digital Economy and Green Economy——An Empirical Analysis Based on the Guangdong-Hong Kong-Macao Greater Bay Area

通过构建数字经济与绿色经济水平评价指标体系,测算了粤港澳大湾区两个系统的耦合协调水平,并进一步运用结构方程模型,分析了融通创新对二者协同水平的驱动效应。结果发现:大湾区数字经济与绿色经济耦合协调水平经历低度、中度、高度、优质耦合4个阶段,香港地区的协同水平居于首位,澳门地区次之,广东与前二者的差距逐年缩小,融通创新要素中政策支持对二者的协同水平无直接显著影响,但可通过企业自主研发创新间接作用于后者,企业自主研发创新和产学研合作创新均对协同水平有显著的正向作用,同时,产学研合作创新还可通过企业自主研发创新间接正向作用于二者的协同水平。

This study calculated the coupling and coordination level of the two systems in the Guangdong-Hong Kong-Macao Greater Bay Area by constructing the evaluation index system of digital economy and green economy level,and further analyzed the driving effect of integration innovation on the synergy level of the systems by using structural equation model.The results showed that the coupling coordination level of digital economy and green economy in the Greater Bay Area had experienced four stages of low,medium,high and high-quality coupling.The synergy level of Hong Kong took the first place,followed by Macao,and the gap between Guangdong and the former two was narrowing year by year.Among the factors of integrated innovation,policy support had no direct and significant influence on the synergy level of the two,but could indirectly affect the latter through independent R&D innovation of enterprises.Enterprise independent R&D innovation and industry-university-research institute cooperative innovation both had a significant positive effect on the synergy level,and the latter also indirectly had a positive effect on the synergy level through the former.
