Study On The Relationship Between Population Migration And Economic Development In The Three Provinces Of Northeast China

The three Northeast provinces have made great contributions to China’s economic development as the most important heavy industry bases in China.However,the population loss in Northeast China has been the focus of attention of the society since the reform and opening.In the context of the obvious decline in economic development,it is of great theoretical value and practical significance to study the relationship between economic development and population migration.In recent years,according to the GDP growth rate of various regions of the country,China’s economic development has been characterized by the fastest in the west,the second in the middle,the slowdown in the east,and the weakest in the northeast.Along with the gradual decline of the economic development of the Northeast region,it has forced a large number of people to move out of the area.The population in the Northeast has changed from a net inflow to a net out.The mass migration has seriously affected the economic development of the region.Based on the data from the fourth,fifth,and sixth national censuses,this thesis summarizes the characteristics of population migration in the three provinces of Northeast China,and analyzes the spatial characteristics of migration based on the data of population migration in prefecture-level cities.Finally,the grey correlation method is used to measure the correlation between the indicators of migration system and the economic development system.Then,regression models of indicators of two systems as explanatory variables are respectively established to further explore the relationship between population migration and economic development.Through research,this thesis draws the following conclusions:(1)The population in Northeast China has shifted from the net inflow of population in the fourth national census to the net outflow in the sixth national census,and the number of the population migration has shown an expanding trend.Affected by the geographical location and economic development,the size of Heilongjiang’s migrant population is the largest among the three provinces.The migration population in the three provinces is dominated by intra-provincial migration,and their proportion is gradually increasing.(2)The inter-provincial immigration population mainly comes from neighboring provinces.With the development of the economy,the inter-provincial immigration population to the more economically developed eastern regions has gradually increased.Employment and business have become the main reasons of population migration.Economic momentum has become one of the main driving forces for populationmigration in the Northeast.(3)The population distribution in Northeast China is mainly based on the four sub-provincial cities,such as Shenyang and Dalian.And the population migration flow of prefecture-level cities is from the remote and economically backward areas to the more concentrated population distribution and more developed cities.Moreover,the population migration rate in Northeast China does not have spatial autocorrelation.(4)The increase in rural per capita net income is conducive to attracting people to move in and inhibiting them from moving out.In addition,the output value of industrial enterprises above designated size has different impacts on population migration due to the changes of population migration and socio-economic development.Moreover,it has been found that the economic development indicators and the degree of impact on population migration were different during the two periods.Population migration has a significant impact on economic development.The development of the secondary and tertiary industries and the degree of market openness have a positive impact on regional economic development.
