The Research On The Spatial Evolvement And Movement Of The Economic Gravity Center And Population Gravity Center Of Northeast China

Regional development is always the problem of the key problem in the study of theregion, Most of the academic research achievements analysis of the status quo, causes andevolution of the regional difference characteristics and future trends, etc.Some scholars ofeconomic gravity model is used to study differences in characteristics and evolutionmechanism of regional economic development.To reveal the evolution of spatial pattern ofregional economy, and gives a scientific and reasonable regional development Suggestions.This paper uses the basic knowledge and principle of economic geography, humangeography, geography information system, Study since1992, the northeast regional economiccenter of gravity, the industrial center of gravity, center of gravity and center of gravity of themovement, And analyzes the evolution and the reasons for change, So as to provide evidencefor future regional development policies in northeast China. This article USES the qualitativeanalysis and quantitative analysis, comparative analysis research method, using GIS mappingsoftware, Calculating GDP, population, total output value of tertiary industry, theconsumption data in order to get the center of gravity location coordinates, And differentyears of economic barycenter and population center of gravity, by adding to theadministrative zoning map to get the dynamic changes of the northeast region’s center ofgravity vector diagram, visually shows the northeast area economy development spacedifference of the change process.Based on the background and existing research results,this study focus on the evolutionpath of gravity center of economic,population,industry and consumption,and then provideeffective regional policies to promote regional development of Northeast China bycomparison analysis.This study includes six parts.The first part introduces the background,significance and methods of the research.The second part focuses on the economicmeaningand a brief description of measurement methods and focuses on space evolutionmechanismof the gravity center of economic and population.The third part describes themovement routeof economic gravity center of Northeast China in the view of industry gravitycenter.The fourth partdescribes the movement route of population gravity center of NortheastChina and analyzes theregional difference in Northeast China,then it describes the movementroute of consumptiongravity center of Northeast China and analyzes the regional difference inNortheast China.The fifth partmakes a comparison analysis about the gravity center ofeconomy,population,industry andthe consumption.The sixth part is not only emphasizes on the previous theoreticalsummary of the content,but also briefly summarizes some significantpolicyrecommendations.
