| Since the reform and opening up,Jiangsu’s industrial economy has maintained a high-speed growth trend,but at the same time it is facing increasingly serious problems of resources and environment.As a typical example of China’s industrial economic growth,its industrial development path and source of economic growth are the focus of attention.As far as Jiangsu Province is concerned,in order to alleviate the pressure of resources and environment,smoothly realize industrial transformation and continuously enhance regional strength,it is necessary to clarify its own level of resources and environment utilization and promote regional cooperation and development.Therefore,it is of great significance to select a scientific and reasonable measurement model of industrial environmental efficiency to analyze the quality of industrial economic growth and its regional differences in Jiangsu Province.Taking the industrial environmental efficiency of Jiangsu Province as the research object,this paper selected relevant data from 2010 to 2016.Firstly,based on the SBM-Undesirable model,the paper analyzes the industrial environmental efficiency and its temporal and spatial differences in Jiangsu Province from a static point of view.The industrial environmental efficiency is decomposed into pure technical efficiency and scale efficiency to identify the influencing factors of the industrial environmental efficiency of Jiangsu Province,and the regional differences of the environmental efficiency are analyzed by using the Theil index method.Based on the meta-frontier theory,the industrial environmental efficiency of counties in Jiangsu Province considering technology heterogeneity is calculated,and the regional differences are analyzed.Next,this paper uses Malamquist-Luenberger productivity index to measure the dynamic evolution of industrial environmental efficiency in Jiangsu from a dynamic point of view,and decomposes it into technological progress index and technological efficiency change index,so as to explore the driving mechanism of the change of industrial environmental efficiency in Jiangsu.The empirical results show that:(1)The overall industrial environmental efficiency of Jiangsu Province is at a low level,the average efficiency is only 0.4412,which has great potential for improvement.Moreover,industrial environmental efficiency in Jiangsu Province is mainly driven by scale efficiency,and pure technical efficiency is the main reason that hinders the further improvement of industrial environmental efficiency.Jiangsu Province shows the characteristic of "South Jiangsu>Central Jiangsu>North Jiangsu" in terms of efficiency and technology level,with significant regional differences,but the technological gap between the central region and the southern region is decreasing,and the technological gap between the northern region and the southern region is also decreasing year by year;(2)The overall gap of industrial environmental efficiency in Jiangsu Province is gradually decreasing,and the main reason for the formation of the overall gap is the regional internal gap,and the internal gap in the central Jiangsu is the biggest cause of the internal gap in the whole area of Jiangsu Province.(3)The dynamic efficiency of industrial environment in Jiangsu Province has made progress,with an average annual growth rate of 9.92%,and the industrial environmental efficiency in northern Jiangsu has the fastest growth.The industrial environmental efficiency of Jiangsu Province is mainly driven by technology progress,and the stagnation of technology efficiency is the reason that restrains the further improvement of industrial environmental efficiency.Finally,according to the above empirical analysis and the current situation of industrial development in Jiangsu Province,the policies and suggestions for improving industrial environmental efficiency in Jiangsu Province are put forward:(1)change the mode of economic development,promoting the transformation and upgrading of industrial structure,speeding up the process of industrialization,and realizing sustainable development;(2)learn advanced management methods actively,promoting the common development of industrial technology and management,and realizing the dual wheel drive of environmental efficiency;(3)strengthen regional exchanges to narrow the gap within the region;(4)strengthen publicity efforts to enhance the environmental protection awareness of the government,enterprises and the masses.Figure 11 table 5 reference 80. |
