| The promotion of the coordinated development level of regional economic-social-envi-ronmental system is an important reflection of the quality of regional development and the ability of sustainable development,which is related to the improvement of the quality of life and happiness of the broad masses of the people.Northeast is an important heavy industry base and ecological barrier area in China.Its development quality and characteristics are related to the process of national industrialization and national ecological security.In modern times,with the rapid development of social economy and abundant natural resources and location conditions,Northeast has rapidly become an industrial town from the barren land outside the Shan-Hai-Guan and has been in the forefront of Asia.However,with the global spread of marketization and modernization,the mechanism of acceptance system and natural resources in Northeast China are facing exhaustion and other factors,the speed of economic development is declining,and the transformation and upgrading of industrial structure is very difficult.Since 2003,the state has implemented the strategy of "Revitalizing Northeast China".With more than ten years of efforts,the industrial transformation and upgrading in Northeast China have made progress,the infrastructure has been gradually improved,the pace of reform of state-owned enterprises has been accelerated,and the economic development benefits have been continuously improved;However,with the gradual improvement of social economy,new changes have taken place in the ecological environment,and the problems of water environmental pollution,air quality decline and land loss are becoming more and more serious.Therefore,since the revitalization of the Northeast China,the study of the evolution characteristics of the economic-social-environm--ental system and their interrelationship has certain value for us to fully understand the achievements and problems of the revitalization strategy.Based on this,this paper analyses the spatial and temporal characteristics of the evolution of the economic-social-environmen--tal system in Northeast China since its revitalization,and the horizontal process and spatial pattern of its coordinated development by means of the entropy method and the coupling coordination degree model;By means of multi-distance stepwise regression model and geographically weighted regression model,this paper explores the influencing factors of regional coordinated development level and the differences of their forces.The results show that:(1)The overall level of coordinated development of the economic-social-environmental system in Northeast China is on the rise year by year,that is,the level of coordinated development of the economic-social-environmental system is constantly improving,but the spatial differences are large,and the high-value areas are concentrated along the Ha-da Line and in the eastern part of Northeast China.(2)From the perspective of influencing factors,the response intensity of the southern region to urbanization level,industrial level,service level,resource consumption and other factors is greater than that of other regions.The level of scientific and technological input shows obvious time characteristics.it played a strong role in the eastern region in 2008,and it turned to the southern coastal region in 2013.(3)For the future development of Northeast China,efforts should be made to speed up the adjustment of industrial structure,promote the all-round development of human beings,strengthen environmental governance,and realize the coordinated development of the economic-social-environmental systems in Northeast China.The full text is divided into six chapters:Chapter I,introduction.Discusses the research background,significance and objectives,as well as the research contents.Chapter ?,literature review and theoretical support.According to the research content of this paper,the related progress of the coordinated development of economy,society and environment at home and abroad is discussed.The regional growth pole theory,sustainable development theory and regional coordinated development theory are emphatically defined.Chapter ?,the construction of index system and evaluation method.This paper introduces the sources and processing methods of the data used,constructs the evaluation index system from the aspects of economic basis,economic benefit,social basis,social service,environmental basis and environmental response,and finally introduces the research model method used in this paper.Chapter ?,analysis of the coordinated development pattern of economy,society and environment.Based on the comprehensive level of economy,society and environment in 2003,2008,2013 and 2016,the spatial pattern of regional economic,social and environmental development level since the revitalization of Northeast China is analyzed.The temporal and spatial characteristics of the coordinated development level of the three areas are analyzed by using the coordinated development model.Chapter ?,influencing factors and suggestions of coordinated development level.This paper analyses the influencing factors from seven aspects: urbanization level,industry level,service industry level,science and technology input level,urban land output level,resource consumption level and urban intensive level,and then puts forward countermeasures and suggestions to promote the coordinated development of economy,society and environment in Northeast China from three dimensions: economic restructuring,comprehensive human development and ecological environment governance.Chapter ?,conclusion and prospect.This paper summarizes the main research conclusions of the full text,and prospects the existing problems and future research directions.. |
