摘　　要：加快长三角城市的绿色发展转型,是长三角城市在一体化进程中维持区域可持续发展的必然要求。文章运用2012-2019年长三角41个城市的面板数据,探究长三角一体化对城市绿色发展的影响效应,同时考查创新投入的中介效应和城市群扩张的政策效应。研究结果表明:长三角一体化对城市绿色发展具有抑制作用,且这种作用具有区域异质性;增加城市创新投入可有效缓解城市一体化对绿色发展的抑制作用。进一步研究表明,长三角一体化对城市绿色发展存在空间溢出效应,长三角城市群扩张能够显著促进城市绿色发展。To speed up the green transformation is an essential requirement for the Yangtze River Delta cities to achieve regional sustainable development in the integration process.This paper uses the panel data of 41 cities in the Yangtze River Delta from 2012 to 2019 to explore the effect of the integration of the Yangtze River Delta on the urban green development,taking into account the mediating effect of innovation input and the policy effect of urban agglomeration expansion.The results indicate that the integration of the Yangtze River Delta has an inhibitory effect on the urban green development,and this effect has regional heterogeneity.Increasing the urban innovation input can effectively alleviate the inhibitory effect of the integration on green development.Further study shows that the integration of the Yangtze River Delta has a spatial spillover effect on the urban green development,and the expansion of the Yangtze River Delta urban agglomeration can significantly promote the urban green development.
