产业协同集聚对城市经济绿色发展的影响

Research on the influence of industrial collaborative agglomeration on the green development of urban economy

基于中国东部沿海地区66个城市2009—2018年的面板数据,采用空间计量模型,通过拓展多维邻近概念,对地理邻近、信息邻近与交通邻近及多维交互邻近下产业协同集聚对城市经济绿色发展的影响进行研究。研究结果表明,产业协同集聚与城市经济绿色发展存在显著的空间相关性,各种邻近维度下产业协同集聚均可有效推进城市经济绿色发展。其中,三维度交互邻近下要素之间的空间联动性最为突出,地理距离弱化了信息化邻近和交通发展交互带来的溢出效应。城市群尺度的研究结果显示,产业协同集聚可以持续推动本区域的经济绿色发展,而对邻近区域经济的绿色发展具有异质性影响。

Based on the panel data of 66 cities in the eastern coastal area of China from 2009 to 2018,using spatial econometric model,by expanding the concept of multi-dimensional proximity,this paper studies the impact of industrial collaborative agglomeration on urban economic green development under geographical proximity,information proximity,traffic proximity and multi-dimensional interactive proximity.The results show that there is a significant spatial correlation between industrial collaborative agglomeration and urban economic green development,and industrial collaborative agglomeration can effectively promote urban economic green development under various adjacent dimensions,among which,the spatial linkage between elements under three-dimensional interactive proximity is the most prominent,and geographical distance weakens the spillover effect caused by the interaction between information proximity and traffic development.The research results on the scale of urban agglomeration show that industrial collaborative agglomeration can continuously promote the green economic development of this region,but has a heterogeneous impact on the green development of neighboring regions.
