| Since the reform and opening up in 1978,China has entered a historical stage of comprehensive transformation and transformation.Great changes have taken place in China's economy and society,Especially the economy has entered a "fast lane" of sustained and rapid development.From 1979 to 2016,China's GDP growth rate averaged 9.6% annually,creating a "growth miracle" of the world economy.In terms of total GDP,China surpassed Japan for the first time in 2010 and became the second largest economy in the world.In 2017,China's total GDP reached 82.71 trillion yuan,far surpassing Japan and ranking second in the world,surpassing 60% of the total US economy,which is equivalent to the total GDP of Japan,Germany and Britain.In terms of per capita GDP,China's ranking in the world rose from 175 in 1978 to 100 th in 2014,close to the average level of middle-income countries.In 2016,China's per capita GDP reached 53,980 yuan,ranking 69 th in the world.The total economic output and per capita GDP of some developed provinces and cities such as Beijing and Shanghai exceeded the level of the world's medium-developed countries.However,for quite a long period of time,China's economy has been pursuing high-speed GDP growth unilaterally.Economic growth mainly depends on external demand and investment,ignoring the quality and efficiency of economic growth,and has formed an extensive economic growth mode characterized by "high input,high energy consumption,high pollution and low output".At the same time,the deep-seated contradictions associated with China's rapid economic growth are increasingly exposed,and more and more prominent,reflected in economic,social and ecological aspects,such as low per capital income,low overall economic quality,large gap between urban and rural areas,low level of industrial structure,weak ability of scientific and technological innovation,lagging urbanization development,underdeveloped financial system and capital.Source and environment constraints are tightening.These structural contradictions constitute unfavorable factors and potential threats to the long-term sustainable and healthy development of China's economy at the present stage and for a considerable period of time in the future.In order toaccelerate the "four modernization synchronization" construction of industrialization,information,urbanization and agricultural modernization in China,and comprehensively promote the "five in one" development of economy,politics,culture,Society and ecology,it is urgent to find solutions.On the basis of systematically combing the relevant theories of economic development,fully combining the contents of relevant disciplines such as development economics,institutional economics and relevant research trends at home and abroad,this paper attempts to construct a theoretical analysis framework of narrow-sense economic development quality and broad-sense economic development quality,including the connotation,influencing factors,mechanism of action,measurement and evaluation of economic development quality.Based on the theoretical basis and practical basis of China's economic development,combined with the green total factor productivity and the development concept of "innovation,coordination,green,openness and sharing",this paper makes an empirical analysis of the measurement,spatial and temporal evolution and influencing factors of the quality of economic development of China and its regions and provinces in 2003-2016,with a view to making a scientific,comprehensive and objective comprehensive evaluation,and puts forward some suggestions.Path Selection and Countermeasure Suggestions for High-quality Development of National Economy.Firstly,by discussing the related concepts of economic development in political economics,classical economic growth theory,neoclassical economic growth theory,new growth theory,development economics,institutional economics,sustainable development theory and inclusive development theory,this paper advances the concepts of economic growth,economic development,economic development efficiency,economic development quality and economic development efficiency.Definition and analysis should be made to clarify the connotation of narrow economic development quality and broad economic development quality.In the narrow sense,the quality of economic development is equal to the efficiency of economic development.The representative index is green total factor productivity,which notonly reflects the comprehensive level of productivity and its changes,but also takes into account the factors such as resource utilization and environmental pollution.In the broad sense,the quality of economic development includes not only the connotation of "quantity",that is,the growth of economic quantity and scale,but also the connotation of "quality".The advantages and disadvantages of economic,social and ecological development are the organic combination of quantity and quality.On this basis,the connotation,measurement and influencing factors of narrow economic development quality and broad economic development quality are reviewed respectively.Secondly,according to the narrow definition of the connotation of economic development quality,this paper uses the super-efficiency SBM directional distance function based on unexpected output and Malmquist-Luenberger index model to measure China's green total factor productivity from 2003 to 2016,compares and analyses the GML index of green total factor productivity and the regional and provincial disparities of its component changes,and compares the differences between China and other provinces.This paper makes an empirical analysis of the narrow-sense factors affecting the quality of economic development in the four regions of the east,central,West and northeast.According to the broad connotation of economic development quality and five development concepts,a comprehensive evaluation index system consisting of five dimensions,12 sub-indicators and 24 basic indicators is constructed.The weight of each indicator in the index system is calculated by using the method of entropy value,and the quality index of economic development of China and 30 provinces in 2003-2016 is calculated,as well as innovation development,coordinated development,green development and open development.Exhibition and sharing development dimension index,calculate the global index value of China's economic development level in 2003-2016 and the local index value of China's provinces in 2003 and 2016,and explore the spatial correlation and spatial agglomeration effect of economic development quality.Finally,the paper puts forward the path selection and Countermeasures forChina's high-quality economic development,including innovation-driven development path,structural optimization development path,ecological green development path,high-level open development path and achievement sharing path.The countermeasures and suggestions include building a coordinated economic pattern,cultivating "new momentum" of economic development,and creating a high-quality economic development ring.Context,the Leading Position of Global Value Chain and the Establishment of Institutional Mechanisms for High-quality Economic Development. |
