A Study On The Spatial And Temporal Evolution Of Economic Center Of Gravity And Population In Liaoning Province

The balanced development of the region has always been the focus of research on regional economic development.The research results have been mainly aimed at the causes of regional economic disparity,the current situation of regional economic differences,the evolution laws and the means of control.The center of gravity model to analyze the characteristics of regional economic differences,the evolution of the causes and evolution process,and then by analyzing the previous economic policy to give appropriate regional development proposals.This paper mainly uses the theoretical knowledge of related disciplines such as human geography,economic geography,regional development and planning,geographic information system,and so on.By using comparative analysis,qualitative and quantitative research methods,this paper analyzes the GDP of Liaoning Province in 2000-2000,The amount of output,the total amount of fiscal revenue and expenditure,the amount of foreign investment,the amount of fixed assets investment,the number of population and the number of employed population and other data to calculate the geographical coordinates of the center of gravity,the use of Arcgis software will focus on each year in the Liaoning Province The author analyzes the causes of the economic center of gravity and the evolution of the population center of gravity and the reasons for the change,and explores the change process of the regional economic development differences in Liaoning Province,so as to develop for the Liaoning province.Future regional development policy to provide reference.This paper is divided into six chapters: The first chapter introduces the research background and significance of this paper,summarizes the reasons and focus of economic differences at home and abroad,and finally introduces the innovation and shortcomings of the article.Chapter 3 uses the center of gravity model to calculate the economic center of gravity evolution in Liaoning Province from 2000 to 2015,and the three industrial centers of gravity and the economic center of gravity were carried out.This paper analyzes the impact of the five centers of gravity,such as finance,foreign investment,fixed assets investment and consumption,on the economic center of gravity.The fourth chapter calculates the population center of Liaoning Province from 2000 to 2015,depicts its moving trajectory and its causes The fifth chapter compares the economic trajectory of economic and population focus in 16 years in Liaoning Province and measures its coupling.The sixth chapter concludes the conclusion.
