Study On The Coupling Relation Between Population Structure And Economic Development Of Urban Agglomeration In The Middle Reaches Of The Yangtze River

The problem of population and economy is the most fundamental and important problem of human society,and it is an important factor restricting and influencing the social and economic development of the country.In 2015,the development plan of the middle reaches of the Yangtze river reaches the national development strategy;Based on the research theories and research methods of demography,Demographic?Population economics?Human geography?Regional economics?Population geography?Metrology and so on;It is a research unit of 31 prefecture-level cities in the middle reaches of the Yangtze river;the2000and 2010 census data of human,the data of 1% of the national population in 2015 and the statistical yearbooks of Jiangxi,Hubei and Hunan provinces in 2000 and 2015 were used;Measurement software platform based on ArcGIS space and SPSS?Excel and other statistical measurement analysis platform,urban agglomeration in the middle reach of Yangtze river in the population structure and economic development on the basis of the present study,build the index system of population structure and economic development,establish a grey correlation analysis model,to explore the coupling of space and time distribution of population structure and economic development and mutual influence mechanism analysis of population structure and economic development,in order to make urban agglomeration coordinated development of population structure and economic development in the middle reach of Yangtze river will provide a scientific basis for policy recommendations.The following conclusions are drawn from the study:(1)The structure of the urban agglomeration in the middle reach of Yangtze river population optimization,rapid economic development,population structure and economic development but area space differentiation,unbalanced regional development,Wuhan,Changsha,2015 location entropy higher status in regional economy.(2)The population structure and economic development of the middle reaches of the Yangtze river are medium and high,and the areas with high coupling degree are concentrated in the "Green heart" of the middle reaches of the Yangtze river.The coupling type in the region is dominated by the coupling zone and the antagonistic coupling,and the low level coupling is the auxiliary.The coupling and coupling types change over time in space.(3)The correlation between the population structure and economic development of the middle reaches of the Yangtze river is medium and high.Population structure,population age structure to economic development,workforce to provide power for economic development,the population of higher education is beneficial to promote the development of the economy.The improvement of the economic level has kept the population structure optimized,and the population structure has also promoted the economic development.According to the relevant research results,relevant policy Suggestions are put forward in order to promote the coordination of population structure and economic development of urban agglomeration in the middle reaches of the Yangtze river.
