Comparative Research On Regional Eco-economic Efficiency Based On Network DEA

Cities are the main carriers of human's production and life.Urban agglomerations are the highest form of spatial organization in the development of the city,and are the main form of the new urbanization.With the rapid development of China's economy,China is facing ecological and environmental problems.Therefore,promoting the transformation of the economic structure and the production mode,promoting the healthy development of urban agglomerations are the keys to reform.Regional Eco-economic System is a composite network system that integrates economic,environmental and social ecologicalization.Constructing a regional Eco-economic system evaluation index system coupling economic-social-ecological,the Eco-economic efficiency of urban agglomerations can be measured,and thereby the coordination level of regional Eco-economic systems can be quantitatively characterized.According to the above,the article takes the Beijing-Tianjin-Hebei,Yangtze River Delta,and Pearl River Delta urban agglomerations with the most mature urbanization development in China as the research sample,takes a matrix network DEA and a global spatial auto-correlation test as the methods to dynamically calculate the regional Eco-economic efficiency of the three major urban agglomerations from 2012 to 2017,with a view to providing suggestions for improving the Eco-efficiency,providing a demonstration for the development of other urban agglomerations as well.Firstly,according to the particularity of the research object's development,the article constructs an evaluation index system applicable to the measurement of the Eco-economic efficiency of the three major urban agglomerations.Next,the matrix-type network DEA method and a global spatial auto-correlation test are used to measure the Eco-economic efficiency of the three major urban agglomerations.Then,based on the actual situation in the Yangtze River Delta,the Pearl River Delta,and the Beijing-Tianjin-Hebei Region,an empirical analysis of the Eco-economic efficiency of the three major urban agglomerations is made.The results of the study found that: First,there are significant differences in the development of Eco-economic efficiency among the three major urban agglomerations.ThePearl River Delta urban agglomeration has the highest Eco-economic efficiency;the Beijing-Tianjin-Hebei urban agglomeration is the second,but its Eco-economic efficiency has been increasing at a rapid rate;the Yangtze River Delta urban agglomeration has the lowest.Second,Compared with the economic subsystem,the social subsystem and the ecological subsystem are more important factors affecting the Eco-economic System.Third,from the analysis of spatial evolution and agglomeration characteristics,it is found that the overall performance of the cities in the Pearl River Delta are good,but it is necessary to pay attention to social efficiency;the Eco-economic efficiency of the cities in the Yangtze River Delta is clearly divided into two levels;the spatial agglomerations in Beijing-Tianjin-Hebei need to be strengthened.Finally,based on the results of empirical research,practical policy suggestions are put forward from the actual point of each urban agglomeration,for example,increasing investment in ecological environment,strengthen the effect of environmental regulations;breaking through administrative barriers to strengthen the normalized regional dialogue mechanism;upgrading the industrial structure and increasing the added value of science and technology;Increasing investment in science,education,culture and health,so as to give play to human capital spillover effect.
