国家自主创新示范区设立对城市绿色科技创新的影响研究
Research on the Influence of the Establishment of National Independent Innovation Demonstration Zone on Urban Green Science and Technology Innovation
摘要
Abstract
Green technology innovation is an important driving force for promoting high-quality development in China.The development of green technology innovation cannot be separated from the support and guidance of national independent innovation demonstration zones.In recent years,various regions have been approved to establish demonstration zones.It is unclear whether this measure can promote green technology innovation in Chinese cities.This article uses the double difference method to analyze the impact of the quasi natural experiment of setting up a demonstration area on urban green technology innovation.It selects the addi-tion of control variables and the counterfactual test method for robustness testing,and conducts lag exploration and heterogeneity a-nalysis.The results show that:(1)the establishment of demonstration zones has a significant positive promoting effect on urban green technology innovation.(2)There is a certain lag in the promotion effect.(3)Heterogeneity analysis shows that the estab-lishment of demonstration zones has significant differences in the impact of green technology innovation on cities in different regions.It has a significant impact on green technology innovation in regions with higher innovation levels,while the effect on green technolo-gy innovation in cities with lower innovation levels is not significant.关键词
