摘要
根据2003—2018年京津冀、珠三角、长三角及成渝4个国家级城市群82个城市的面板数据,应用空间杜宾模型研究了区域协同创新对绿色经济发展的影响,并分析金融发展和政府科技创新财政支出对该效应的影响。结果表明:区域协同创新可以促进城市群整体的绿色经济发展水平,但对不同城市群影响效应表现存在差异;金融效率的提高与金融结构的优化有利于发挥城市群区域协同创新对绿色经济的促进作用,而金融规模的扩大对不同城市群的影响不同;随着政府科技创新支出比例的提高,京津冀和成渝城市群区域协同创新对绿色经济发展的影响效应分别呈现单一门槛与“N”型双重门槛特征。
Based on the panel data of 82 cities in four national-levelurban agglomerations,namely,Beijing-Tianjin-Hebei,the Pearl River Delta,the Yangtze River Delta and Chengdu-Chongqing,from 2003 to 2018,this paper applies the Spatial Durbin Model to study the effect of regional synergy innovation on green economic growth,and further analyzes the effect of fiscal expenditure and financial development on this effect.The result shows that:firstly,regional synergy innovation has a positive effect on the green economic growth,but it manifests itself differently in different regions.Secondly,the increase of financial efficiency and the optimization of financial structure help the regional synergy innovation contribute to green economic growth,while the expansion of financial scale effect are differently in different regions.Thirdly,with the increase of fiscal expenditure about technological innovation,the effect of synergy innovation on the green economic growth of Beijing-Tianjin-Hebeiregion and Chengdu-Chongqing region demonstrates significant single and N-type double threshold features.
