The Analysis Of Regional Economic Growth Astringency,Parametric Heterogeneity And Growth Source Based In Multilevel Model

This paper analyzes the characteristics and influencing factors of regional economic growth in China from two parts.The first part of the article analyzes the economic growth of China's regional economic convergence and heterogeneity parameters,used data are based on our country more than 280 local and city economic data of 2000-2015,the city as a level1,provinces and autonomous regions as a 2 level,resulting from a two level model,the data first empty model,in order to verify the necessity of multi level model of data modeling,data exists between groups heterogeneous conclusion,so should use the multiple level model is analyzed.Then the effect of random regression model analysis,on the basis of an empty model to join the 1 level variables,this part proves the importance and necessity of using multiple level model,and through the interaction effect between provinces and regions was proved by significant heterogeneity parameters.The increase of material and human capital will promote regional economic growth,while in the case of technological progress rate and capital depreciation rate,population growth will hinder the growth of regional economy.The second part is to use multiple levels model analyses the influence factors of economic growth in China,is used data from 1996 to 2015,the national economic development data of 30 provinces and autonomous regions to use multivariate linear model to fit the data,in order to achieve more accurate results,the data set up two level model and single variable condition and unconditional level model of economic growth and labor,and capital investment,and the quantitative relationship between the degree of opening to the outside world,and through the equation of calculating total factor productivity growth,in order to analyze the main source of economicgrowth in China,between the provinces of economic growth is mainly driven by capital,which includes technical progress and the improvement of technical efficiency,scale effect,and the other is not yet clear is also very obvious impact on economic growth,and growth of the labor force for the conclusion of the role of smaller economic growth.At the end of the article,the author puts forward some Suggestions to promote China's economic development from three aspects: opening up,technological progress and strengthening labor quality.The innovation of this paper lies in the successful application of multi-level models to the economic field,which provides a new way of thinking for the study of economic growth,and provides a more accurate result.
