数字经济发展对城市绿色创新的影响研究
Research on the Impact of Digital Economy Development on Urban Green Innovation
摘要
Abstract
How to improve the level of green innovation is an issue that China pays close attention to.In the process of green technology research and development,the digital economy should play a role.Thus,this paper takes 270 cities from 2011 to 2022 as sample data,examines the impact of digital economy on green innovation and its heterogeneity,and further uses the threshold spatial Durbin model to test the asymmetric spatial spillover of green innovation.The results show that:First,the development of digital economy has significantly promoted green innovation in local and neighboring cities.The digital economy plays a greater role in supporting local green innovation in regions with lower environmental regulation intensity,higher intellectual property protection levels and in central China.The positive spillover effect of the digital economy is better reflected in the cities with stronger protection against intellectual property and cities in eastern China.At the same time,the development of digital economy can promote the quality and quantity of green innovation in local and neighboring cities.Second,urban green innovation shows a significant asym-metric spatial spillover effect,and cities with the most developed digital economy obtain the largest positive spatial spillover.关键词
