Analysis Of Economic Disparity And Influencing Factors Based On A Provincial Perspective In The Yangtze River Economic Belt

Since 1978,China's economy has taken off and gotten good grades.However,regional economic differences have become increasingly prominent,and it has become a core issue in geography research and regional development research.The Yangtze River Economic Belt spans the eastern,central and western regions of China,and its economic development is in the forefront of China.In 2018,its GDP reached402,924.24 billion yuan,accounting for 44.76% of the national GDP,and the economic growth rate of 11 provinces and cities is higher than Or it is equal to the national economic growth rate,but there are also problems such as imbalanced economic development within the region and the imperfect regional cooperation mechanism.In this context,the analysis of the provincial economic differences in the Yangtze River Economic Belt has certain research significance.This study is mainly discussed in the following three aspects:First,study the dynamic changes of the economic development of the provinces(nine provinces)of the Yangtze River Economic Belt: depicting the dynamic process of economic development at the provincial level in the Yangtze River Economic Belt from three aspects: GDP and per capita GDP,industrial structure change,industrialization process and urbanization construction..The results show that:(1)Since the 21 st century,the economic differences between the downstream(Jiangsu,Zhejiang,Anhui),the middle reaches(Hubei,Hunan,Jiangxi),and the upstream(Sichuan,Guizhou,Yunnan)have gradually expanded since 2000.The characteristics of 2007-2017 show a trend of gradual shrinking.(2)The production input factors of the nine provinces in the Yangtze River Economic Belt gradually moved from the low-productivity sector to the high-productivity sector,and the industrial structure gradually became rationalized.(3)The urbanization level of the upper,middle and lower reaches is obviously lower than the level of industrialization.Although they are all in the stage of accelerated development,the development is extremely unbalanced,and the midstream and upstream are lower than the national level.Second,measure the comprehensive level and difference analysis of the economic development of the nine provinces in the Yangtze River Economic Belt: Under the background of China's economic development shifting to high-quality development,this paper is from direct economic indicators,innovation-driven,coordinated balance,green low-carbon,open and win-win,Co-construction and sharing of six levels to establish a comprehensive evaluation index system for economic development,using entropy method and AHP weighting method to calculate the score.It is concluded that:(1)In2011-2017,the economic development pattern of the nine provinces is relatively solid,and the development of the upper,middle and lower reaches is quite different.The provinces of Zhejiang and Jiangsu are in the first gradient,and the four provinces of Hubei,Hunan,Jiangxi and Guizhou are in the second gradient.The remaining provinces are in the third gradient.(2)The economic growth level of the three major regions of the upper,middle and lower reaches is different(middle-stream>upstream>downstream),and the regional economic gap is gradually narrowing.(3)While the three provinces of the middle reaches are achieving economic growth,the differences in the level of comprehensive economic development of the three provinces are gradually expanding.(4)Focus on the analysis of the economic development status of the nine provinces in2017 and analyze the economic differences between the nine provinces in terms of six dimensions combining provincial policy guidelines,location advantages,industrial layout,and economic environment.Thirdly,it analyzes the factors affecting the economic differences of the nine provinces in the Yangtze River Economic Belt: using the Moran'I index to measure the spatial correlation of per capita GDP in the nine provinces,on the basis of which thespatial panel model is established.Through comparative screening and statistical testing,the spatial effect is fixed.Spatial error model.The results show that there is a positive correlation between the nine provinces in the Yangtze River Economic Belt,and the two provinces of Zhejiang and Jiangsu can achieve synchronous growth.The three provinces of Yunnan,Guizhou and Sichuan have low-speed loopback effects,and Hubei itself develops better,but there is no strong radiation action.Among the factors affecting economic differences,consumer demand,industrialization level,education level,consumer price index and labor level are the main influencing factors of economic development differences in the nine provinces of the Yangtze River Economic Belt,and the consumption demand,industrialization level and education level among them The influence of various factors is relatively large.
