How does Manufacturing Agglomeration Affect the Efficiency of Green Innovation in Cities?
Given the carbon peak and neutrality goals,it is important to identify and enhance the impact of manufacturing agglomeration on urban green innovation efficiency to achieve high-quality economic development.This article uses a sample of 277 cities at the prefectural level and above from 2006 to 2019 to conduct a systematical analysis of the role of manufacturing agglomeration on urban green innovation efficiency at the theoretical and empirical levels.The study shows that the impact of manufacturing agglomeration on urban green innovation efficiency in a city and its neighboring cities has local agglomeration and spatial spillover effects that are"first increasing and then decreasing"and"first decreasing and then increasing";the non-linear effect is obviously different due to urban characteristics.Further analysis shows that environmental regulation has different focuses on the impact of manufacturing agglomeration on green innovation efficiency in and around the city;the synergistic effect of heterogeneous regulation makes up for the deficiency of a single policy.The research results offer guidance on how to optimize the spatial pattern of manufacturing agglomeration to promote the coordinated development of green innovation between cities to achieve the carbon peak and neutrality goals.
