| The relationship between population distribution and its influencing factors and population distribution and economic development is an important topic of common concern in development economics,population economics and economic geography,and is also the main content of the research on the sustainable development of population,resources and environment in the region.The spatial distribution pattern of population is not only shaped by economic development,but also directly affects the performance of regional economic and social development.Based on the county units in Yunnan Province,This paper explores the population distribution and the spatial and temporal change pattern of the county level in Yunnan Province in the period from 2005 to 2015,and uses SPSS software to use the PCA to discuss the effect of natural,economic,social and historical population on the population distribution of Yunnan county area.Based on the cross-sectional data of 2010 and 2015,the coupling between population distribution and economic development in Yunnan county area is analyzed by the coupling model of population distribution and economic development,and the inherent correlation between population distribution and economic development is revealed,and the results show that the coupling between population distribution and economic development in 2010 and 2015 is at a high level.On this basis,the population and economic development level are referenced to the model,the coordination of population distribution and economic development model is constructed,the coupling and coordination of population distribution and economic development in Yunnan counties are compared,the results show that only 6 counties in the province are the coupling degree and coordination degree of consistency,the rest of the county are coupling values lower than the coordination value,indicating that the overall high level of coupling of Yunnan county area is caused by the level of population development and economic development level".To this end,Yunnan needs to do more to improve the distribution of the county population,to promote economic development. |
