Intra-City Industrial Collaborative Agglomeration, Inter-City Network Connectivity and Green Technology Innovation

Abstract

Using the panel data of 263 prefecture-level cities in China, this article explores the development of green technology innovation under the influence of intra-city industrial collaborative agglomeration and inter-city network connectivity. Regression results prove that both of them can enhance green technology innovation. However, further heterogeneity tests suggest that the promoting power of industrial collaborative agglomeration is only significant in the eastern, central and medium-level cities. Meanwhile, there is a significant negative moderating correlation between industrial collaborative agglomeration and network connectivity. This negative moderating effect is particularly significant in the eastern, high and low-level cities.

Industrial Coagglomeration, Green Innovation, and Manufacturing Carbon Emissions: Coagglomeration’s Dynamic Evolution Perspective

“…Green innovation level (ln Gi ) is the intermediary variable. Patent number, including patent application count and patent authorization count, is the most direct reflection of innovation level [ 27 ]. As not all applied patents can be authorized, the number of patent authorizations can better reveal the regional innovation degree [ 23 ].…”

“…These factors are beneficial for the improvement of green innovation. Studies by Lin et al [ 27 ] and Wu [ 28 ] support that industrial coagglomeration promotes green innovation. However, resource misallocation, enterprise chain extrusion, and low-efficiency balance result from low-level industrial coagglomeration, and the crowding effect caused by overly industrial coagglomeration may also hinder green innovation [ 23 , 29 , 30 , 31 ].…”
