摘要
基于2005—2019年中国266个地级及以上城市的面板数据,采用SBM-DEA模型评价城市绿色创新水平,刻画城市绿色创新的空间演变格局,最后构建空间杜宾模型实证分析不同类型的环境规制视角下城市绿色创新的溢出效应。研究结果显示:①时序发展上,研究期内城市绿色创新呈现东部地区、中部地区、西部地区、东北地区依次减弱的态势,总体上表现为“双M”型波动上升趋势,未来具有较大的增长潜力;②空间演化上,城市绿色创新在空间分布格局上存在明显的区域异质性,整体表现为东部地区主导发展的特征;③城市绿色创新在正式环境规制视角下存在正向溢出效应,在非正式环境规制视角下未产生显著溢出效应。
Effectively promoting green innovation is of great significance to improving the high quality of China's economy.Based on the panel data of 266 prefecture-level and above cities in China from 2005 to 2019,this paper uses the SBM-DEA model to evaluate the level of green innovation and describe the spatio-temporal evolution of urban green innovation.Finally,a spatial Durbin model is constructed to empirically analyze the spatial spillover effect of urban green innovation from the perspective of different types of environmental regulation.The empirical results show that:1)In terms of time sequence development,from 2005 to 2019,urban green innovation showed an upward trend of''double M''fluctuations,with great growth potential on the whole.The growth rate of green innovation level in the eastern region is relatively fast,while the growth rate in the central region,the western region,and the northeast region are relatively stable.2)In terms of spatial evolution,urban green innovation shows strong spatial agglomeration characteristics,and the agglomeration intensity is on the rise.There is obvious regional heterogeneity in the spatial distribution pattern,and the overall performance is the development characteristics dominated by the eastern region.3)Different types of environmental regulations have different effects on the spatial spillover effect of urban green innovation.Formal environmental regulation is not only conducive to the green innovation of local cities but also promotes the improvement of the green innovation level of neighboring cities.Informal environmental regulation can promote green innovation in local cities but has no significant impact on green innovation in neighboring cities.According to the research results,this paper puts forward policy suggestions to promote the improvement of the urban green innovation level in China from the perspective of environmental regulation.First,increase environmental protection subsidies and encourage enterprises to innovate.Second,we should reasonably design environmental policies to prevent pollution transfer.Third,give full play to public power and promote coordinated governance.
