Can Digital Innovation Improve Regional Green Development Efficiency?An Empirical Study Based on 284 Prefecture-Level and Above Cities in China
This study aims to examine the impact of digital innovation on the efficiency of green development,utilizing panel data encompassing 284 cities at the prefecture-level and above in China from 2010 to 2020.The main findings are as follows.Digital innovation can significantly contribute to the efficiency of green development in Chinese cities,but this impact is heterogeneous depending on city location,size and hierarchy;The promotion of digital innovation on China's city green development efficiency is characterized by a double threshold,and the positive marginal effect shows a trend of"strengthening-weakening-strengthening";Digital innovation can not only promote the efficiency of a city's own green development,but also facilitate its neighboring cities'green development through spatial spillover effects.
