Analysis of Influence of Expressway on Efficiency of Green Economy from the Perspective of Industrial Structure Optimization
At present,China's expressway construction layout is becoming more and more perfect,so it is of great significance to explore how to give full play to its strong support for regional industrial structure optimization,and then help the development and transformation of green economy.Based on the panel data of 27 cities in the Zhongyuan urban agglomeration from 2006 to 2019,this paper uses the super-efficiency SBM model to measure their green economy efficiency.It empirically analyzes the impact of expressways on green economy efficiency from the perspective of industrial structure optimization and considers industrial structure optimization as both an intermediary and threshold variable in this context.The threshold effect of industrial structure optimization on the efficiency of green economy of expressway is further discussed.The results show that:there is a"U"shaped relationship between expressway and green economy efficiency in Zhongyuan urban agglomeration.The optimization of industrial structure plays a partial mediating role between expressway and green economy efficiency.There is a single threshold effect in the optimization of industrial structure.With the improvement of the optimization level of industrial structure,the effect of expressway on the efficiency of green economy changes from inhibition to promotion.
