Analysis On The Spatial Pattern And Dynamic Mechanism Of Population Migration In Jiangxi Province Based On ESDA

Population migration and flow is an increasing population phenomenon which isaccompanied by the development of social and economic, and has a very close causalrelationship with economic development. The development of the economy "activate"the migration and flow of population, and it greatly promote the development ofeconomy. Since China’s reform and opening up, the development has proved that thepopulation migration and flow has been and will continue to be strong "engine" topromote the development of regional economy. Studying area scale, structure, spatialpattern and its evolution characteristics of population migration and flows, discussingits intrinsic mechanism, analyzing the coupling between population migration andregional economic development, will help to better grasp the law of populationmigration and flow, set the corresponding policies of population development andregional economic policy for regional, and provide the scientific basis for guiding thereasonable and orderly population migration and flow on the space.This paper,analyze the scale of population migration, structure characteristics, cause of migration,migration flows, spatial pattern and dynamic mechanism, using the populationmigration in Jiangxi province as the research object and based on the methods oftraditional statistical analysis method and spatial autocorrelation method. Theconclusion of this article can be summarized as three aspects:(1) Jiangxi, whose scale of the population migration is large and the increasingspeed is fast since2000, belongs to a net emigration province; Population migrationhas become increasingly active in the province, which the main body migrates amongthe townships inside counties and cities; The age of the migration population ismainly concentrated in the15to44; Different groups of migration have differenceswithin the range of age; On the culture level, migration population is higher than theprovincial average, and the inter-provincial immigration is higher than theinter-provincial emigration; On the career, migration population mainly engages ingeneral technical operation and commerce、service industry; In terms of migrationreasons, the influence of economic factors on migration in the province is not strong;The inter-provincial migration reasons are mainly concentrated in doing business orseeking jobs and learning or training. Population migration flow to municipal districtor surrounding counties and cities in province, and the direction of flowing populationis relatively concentrated, the source of inter-provincial immigrants is mainly from thesix provinces (Hunan, Hubei, Anhui, Zhejiang, Fujian and Guangdong province), Theflow direction of Immigrants mainly concentrated in Nanchang, Jiujiang and Ganzhou;out-migrants mainly comes from Shangrao, Ganzhou, Jiujiang, and Immigrantsmainly flow to Guangdong, Zhejiang, Fujian, Shanghai, Jiangsu and Beijing.(2)The spatial pattern of Population migration. The global spatial autocorrelationcoefficient Moran’s I value is very high in the total migration, the number of immigration and the amount of emigration in the province. It shows that there isstrong spatial dependence on space layout.The global spatial autocorrelationcoefficient of the total migration in the province is the largest, spatial agglomeration isthe strongest. The spatial agglomeration of emmigration in the province is greater thanthe immigration in the province. And there also has the characteristics of obviousspatial agglomeration in the inter-provincial immigraion. The local regionaldifferences of quantity of population migration in Jiangxi province is increasing, thespace polarization effect of migration in the province is enhancing. High and highvalue concentrating area of the total population migration in the province center innanchang and its surrounding counties and cities, It exists positive space effect; YuGanxian of LH type belongs to "collapse" area;Guixi is the type of HL, and it playsradiating and driving, It belongs to the high amount of population emigration in theprovince;Linchuan of HL type district in inter-provincial immigraion has formed thelocal heterogeneous "hot spots". High value and high concentrating areas concentratedin the north-central of Jiangxi, southern region are low value and low concentratingareas.(3)The migration motivation mechanism:through comparing three regressionmodels, we found that space factor is not allow to ignore and its effect is positive,when considering factors about affecting population migration in Jiangxi province; Atthe same time, through analyzing regression models we found that the effect ofproportion of non-agricultural population, the proportion of2&3industry outputvalue, per capita GDP and the number of students is also positive on populationmigration.
