The Study On The Green Innovation Efficiency Of Industrial Enterprises In The Yangtze River Economic Belt

As the leading industry of the Yangtze River Economic Belt,industrial enterprises play an important role in regional development.In the process of development,the Yangtze River Economic Belt industrial enterprises are faced with problems such as environmental pollution,energy exhaustion and lack of innovation ability,and these factors have hindered the healthy development of the economy of the Yangtze River Economic Belt to some extent.In the face of these problems,the Yangtze River Economic Belt can only achie-ve the harmonious development of the economy,energy,and the environment only by sticking to the road of industrial green development.Changing the mode of economic development,adhering to green development,and improving the green innovation efficiency of industrial enterprises as the basic principle are the best choices for both to go hand in hand,so the topic of this thesis has certain theoretical and practical significance.Based on this,this paper first sorts out the related research on green innovation efficiency,and combines related theories with the development situation of the Yangtze River Economic Belt to construct an appropriate evaluation index system for green innovation efficiency of industrial enterprises.Exploring the green innovation pattern and explore the green innovation pattern of the Yangtze River Economic Zone;Then,using the SBM-DEA model and the Malmquist-Luenberger index method,a static and dynamic analysis of the green innovation efficiency of industrial enterprises in the Yangtze River Economic Belt was conducted;Then,using the Tobit model to analyze the influencing factors of the green innovation efficiency of industrial enterprises,and according to the analysis results,Several suggestions were made to improve the green innovation efficiency of industrial enterprises in the Yangtze River Economic Belt.The main conclusions of this paper are:1.The Yangtze River Economic Belt has great imbalances both in the input and output of green innovation,showing obvious regional differences.The lower reaches of the Yangtze River have absolute advantages;in the energy consumption and environmental pollution,the Yangtze River Economic Belt The provinces and cities have achieved certain results in energy conservation and emission reduction,energy consumption problems have been eased,and environmental quality has gradually improved.2.In terms of the static efficiency of green innovation,from 2008 to 2015,the green innovation efficiency of industrial companies in the Yangtze River Economic Belt has shown an overall upward trend,with an average efficiency of 0.615,which has a certain amount of room for growth,and the efficiency of green innovation in downstream,upstream,and midstream industrial enterprises has been decreasing.Compared with traditional innovation efficiency,green innovation efficiency has a certain degree of decline every year compared with traditional innovation efficiency.This shows that the constraints of the environment and energy have caused a certain loss to the efficiency of green innovation.3.In terms of total factor productivity of green innovation,total factor productivity of green innovation of industrial enterprises in the Yangtze River Economic Belt has maintained an upward trend.From 2008 to 2015,total factor productivity has increased by an average of 10.0%annually.The growth of total factor productivity in the upper reaches of the region mainly depends on the improvement of technological level.The growth of total factor productivity in the middle reaches is mainly due to the improvement of technical efficiency.The growth of total factor productivity in the downstream areas is driven by the improvement of technical efficiency and the progress of technological level.4.In terms of the factors affecting innovation efficiency,the level of economic development,the intensity of environmental regulation,and the industrial structure all have a positive and positive effect on the green innovation efficiency of industrial enterprises in the Yangtze River Economic Belt;the degree of openness to the outside world is significantly negatively correlated with the efficiency of green innovation.
