Analysis On The Measure And Spatial-temporal Evolution Characteristics Of Regional Green Development Level Differences In China

As China’s social development has entered a new era,regional development has also entered a new stage of development,that is,it has changed from the stage of high-speed growth to the stage of high-quality development.The report of the 19 th National Congress of the Communist Party of China made a new statement on the current main social contradictions in China,emphasizing that "as socialism with Chinese characteristics enters a new era,the main social contradictions in China have been transformed into the contradiction between the people’s growing needs for a better life and unbalanced and insufficient development",and pointed out that in order to solve the problem of unbalanced and insufficient regional development at the emerging stage,we must adhere to the five development concepts,especially the concept of green and shared development.From a quantitative perspective,this thesis scientifically measures the differences of regional green development level in China and analyzes the characteristics of temporal and spatial evolution,so as to scientifically identify the differences and evolution laws of regional green development level,reveal the current situation and problems of regional green development in China,and put forward practical and effective suggestions and countermeasures,which can provide a certain policy basis for the coordinated development of regional green in China in the future.Under the guidance of ecological civilization theory,ecological economics theory,regional coordinated development theory and niche theory,taking 30 provinces and autonomous regions of China as the research object and based on the panel data from 2010 to 2019,this thesis studies the differential characteristics of regional green development in China.Firstly,referring to the research on green development and regional differences,this thesis constructs an evaluation index system of China’s green development level with 51 specific indicators in four subsystem levels: economic development,green ecology,infrastructure and green life;Secondly,based on the niche theory,this thesis constructs the niche situation model of green development,comprehensively evaluates the green development and the development level of four subsystem levels in 30 provinces and autonomous regions of China,and analyzes the development status and trend of green development comprehensive index and four subsystem level index;Thirdly,by improving the Theil index and its decomposition formula,combined with the calculated niche construction and calculating the green development niche Theil index,this thesis further reveals the differences and sources of regional green development in China from the perspective of the whole country,the East,the middle and the West;Then,with the help of Moran index and Moran scatter diagram,this thesis analyzes the regional agglomeration degree of China’s green development level from the perspective of spatial correlation,and investigates the spatial differences of green development level in 30 provinces and autonomous regions;Finally,the convergence analysis of China’s regional green development level reveals the evolution trend of regional differences in China’s green development level.
