The Research On The Spatial And Temporal Evolution Of The Aging Population In Jiangxi Province

The 20 th century was the most rapidly developing century in the history of human society.Under the background of reform and opening up,China has also made great progress in economic aggregate,continuously improved its science and technology,and developed its medical and health undertakings rapidly.On the one hand,it has enabled society to move forward.On the other hand,it has greatly increased human life expectancy.At the same time,the number of elderly people has continued increasing.China has officially entered the aging society since 2000,and Jiangxi Province has entered the aging society since 2005.With the continuous development of the economy,the aging situation has become increasingly severe.It shows the characteristics of large number of elderly people,rapid aging,large number of elderly people in the elderly population,uneven development of urban and rural aging,and mismatch between the economic and population age structure.In view of the regional imbalance and regional differences in the development of the elderly population in Jiangxi province,this paper applies the methods of spatial statistical analysis to the population development research from the perspectives of global spatial autocorrelation and local spatial autocorrelation.GeoDa software is used to explore the spatial distribution of population development in Jiangxi Province.Firstly,this paper analyze the current situation and characteristics of the aging population in Jiangxi Province from the perspective of province,city and country.Next,the spatial statistical analysis method is adopted,Because the elderly have their own characteristics and unique needs,they need to be analyzed with the help of professional disciplines..In addition,the professional subject research is used to obtain the spatial and temporal evolution characteristics of the aging population in Jiangxi Province.Then it analyzes the influencing factors of the distribution of the elderly population in Jiangxi Province,in the help of SPSS software.Finally,comparing and analyzing the spatial distribution of the aging population between Jiangxi Province and Anhui Province,and the same and the different points are obtained.The results showed that:(1)From 1990 to 2010,the population aging coefficient in Jiangxi Province had increased significantly,from 5.09% to 7.60%,and it hadchanged from an adult society to an elderly society.(2)From 1990 to 2010,the spatial differences in the aging counties of Jiangxi Province had gradually expanded and maintained a strong positive correlation.The global indices were 0.313,0.179,and0.148,indicating that the spatial distribution of population ageing in counties and cities was gradually changed into a balanced distribution model development.(3)The decrease in the number of high-value and low-value agglomeration areas in Jiangxi Province indicates that the aging agglomeration effect is weakened.(4)The spatial distribution of the aging population in the counties of Jiangxi Province is affected by the development of population,the level of economic development,cultural education,and medical and health conditions.(5)There are certain similarities and differences in the space-time characteristics between Jiangxi Province and Anhui Province.The degree ofaging of the population is constantly deepening.The degree of aging in Jiangxi Province from west to East is gradually reduced,and the degree of Anhui Province shows that it is decreased from Southeast to Northwest.
