A Study on Spatial Consistency of Population Economy in Yunnan Province
The spatial consistency of population economy represents the coordination degree of population economic development,and the higher the coordination,the better the social development.In this paper,the population and economy of Yunnan Province in 2005,2012 and 2019 were selected as measurement indicators,and the consistency and deviation index models were introduced.The following conclusions were obtained:(1)From 2005 to 2019,the spatial consistent development of population and economy in Yunnan Province showed obvious weak coordination,and the population agglomeration was higher than economic agglomeration,forming the guiding characteristic of population agglomeration leading economic development.(2)The spatial consistency distribution of population and economy in central Yunnan shows the spatial structure of"core layer-outer layer-edge layer"with concentric circles outward,forming the economic agglomeration oriented development from the inside to outside and gradually changing into the population agglomeration oriented development.(3)The range of spatial consistency of population economy keeps decreasing,and the extreme value tends to 1,and the degree of consistency and coordination between population and economy keeps improving.(4)In the change of the proportion of counties in the spatial consistency classification of population economy,fewer counties are in the consistency,and the number of counties tending to the consistency in the fluctuation changes is increasing,forming the characteristics of weak coordination of population economy with population development leading economic and economic development.(5)The range value and mean value of population economic deviation index in Yunnan Province are decreasing,while the number of counties and districts tending to be in the low range of deviation degree is increasing,which reflects the steady and consistent development of population and economy in Yunnan Province.
