Industrial structure upgrading,government's attention to ecological environment and the efficiency of green innovation:Evidence from 115 resource-based cities in China
Green innovation is a strong support for the sustainable economic development of resource-based cities.Exploring the impact mechanism of industrial structure upgrading and the government eco-environmental attention on the efficiency of green innovation,especially in resource-based cities,is of great significance for breaking the lock in the industrial evolution path.Based on the panel data of 115 prefecture-level resource-based cities in China from 2006 to 2020,this article depicted and examined the spatio-temporal evolution characteristics of industrial structure upgrading,government eco-environmental attention and the efficiency of green innovation,using the industrial structure level index,text analysis and the Super SBM-undesirable model.By using multiple linear regression,this study further assessed the influence and function channel of industrial structure upgrading and the increase of government eco-environmental attention on the efficiency of green innovation in resource-based cities.The results showed that:(1)The industrial structure upgrading and the government's increasing attention to ecological environment significantly improved the efficiency of urban green innovation in resource-based cities,and this conclusion remained valid after multiple robustness tests.(2)In terms of the effects of industrial structure upgrading and the government's attention to ecological environment on the green innovation efficiency,the cities of central and western regions were better than the eastern cities,regenerating and mature cities were better than declining and growing cities,and forest-based cities were better than oil-gas type,iron and steel type,ferrous metal-based cities and coal-based cities.(3)The upgrading of industrial structure and the enhancement of the government's attention to ecological environment affect the dynamic change of urban green innovation efficiency through three channels:economic benefit,social benefit and environmental benefit.
