Spatiotemporal Statistical Analysis Of Regional Development Of Poyang Lake Ecological Economic Zone

The establishment of the Poyang Lake Ecological Economic Zone is an important milestone for the rise of Jiangxi.The Poyang Lake Ecological Economic Zone has a strategic and developing layout.Compared with the regional developing strategy(especially the urban population,economy and industry)under the previous administrative unit management model,what characteristics the new developing strategy has are big concerns of the state and Jiangxi provincial government.Based on the situation of regional development of Poyang Lake Ecological Economic Zone,this paper uses non-spatial statistical methods and exploratory analysis methods to explore the regional development of Poyang Lake Ecological Economic Zone during 2004-2013 from two dimensions,space and time for social economic data.According to the analysis of geographical gravity model,from 2004 to 2013,the center of GDP of the Poyang Lake Ecological Economic Zone was always in Nanchang County,and the overall range of movement was small.From 2004 to 2008,the GDP of Fengcheng City,Gao'an City and Zhangshu City rose sharply,and the economic growth rate was greater than that of the northern region.As a result,the center of regional GDP moved southwards.From 2008 to 2012,the economic growth rate of Jiujiang City,which lies in the northern part,gradually increased,leading to the overall shift of the center of regional GDP to the north.The center of overall population of the Poyang Lake Ecological Economic Zone moved to the north as a whole.Overall,the population growth rate in the northern Poyang Lake Ecological Economic Zone is greater than that in the south.The non-agricultural population growth rate in the Poyang Lake Ecological Economic Zone in the northern region is greater than that in the southern region,and western region is smaller than eastern region.According to the analysis results of geographical gravitational model,the intensity of economic ties between counties in Poyang Lake Ecological Economic Zone has been increasing year by year,and the economic development of each county has continued to rise steadily,and the scale of the economy has continued to expand.Through the global and local spatial autocorrelation analysis of the GDP and the year-end total population in the Poyang Lake Ecological Economic Zone during 2003-2014,we can see that the economy and the population of the Poyang Lake Ecological Economic Zone are positively related in space and the closer the distance is,the bigger the correlation is.
