Research On The Impact Of Industrial Agglomeration On Regional Economic Growth Differences

In recent years,China's economic development has been changing with each passing day,and economic growth has achieved outstanding results.Gross domestic product GDP has been rising year after year,and the economic growth rate has gradually stabilized.However,the polarization of economic growth among various regions has been polarized,and the differences in regional economic growth have continued to widen.Traditional economic theories exclude spatial factors and cannot explain China's unbalanced economic growth.Based on this background,this paper focuses on the study of the differences in regional economic growth from the perspective of industrial space agglomeration.Based on the results of theoretical analysis and empirical analysis,it proposes targeted policies to narrow the regional economic growth gap.This article first defines the connotation of industrial agglomeration,analyzes the formation factors of industrial agglomeration,and analyzes the economic effects of industrial agglomeration from four aspects: scale economy effect,regional network effect,product technology innovation and learning effect,and talent sharing effect.Industrial agglomeration affects the regional economic growth by increasing the employment rate,lowering production costs,attracting capital inflows,and promoting the optimization and upgrading of industrial structure.Subsequently,the measurement methods of industrial agglomeration were described in detail,including location entropy index,industry concentration index,Findar-Hirschman index,and space Gini coefficient.Based on the above methods,according to the advantages and disadvantages of each method and the availability of data,the location entropy index was chosen to measure the degree of manufacturing industry concentration from 2005 to 2015.Analyzed the changes of industrial agglomeration in seven regions in China.The differences in regional economic growth include absolute differences and relative differences.The choices are extremely poor,the standard deviation is poor,and the Theil index is used to measure regional economic growth differences in China.It is concluded that the absolute differences in regional economic growth in China are continuously expanding,and the relative differences are continuously decreasing.On this basis,based on the panel data of 2005-2015,this paper empirically analyzes the influence of industrial agglomeration on the regional economic growth difference based on spatial autocorrelation test,LM test and Hossman test.According to the empirical results,relevant countermeasures are proposed and efforts are made to reduce the regional economic growth differences and promote economic growth.The analysis shows that China's manufacturing industry agglomeration phenomenon mainly focuses on the relevant provinces and cities in South China and East China.In recent years,the manufacturing industry agglomeration effect has been remarkable and has increased year by year.There is no significant change in the concentration degree of Northeast and North China.The concentration of manufacturing industries in the southwest and northwest regions has been declining year by year.By measuring the regional economic growth difference,it can be concluded that the absolute difference in regional economic growth between 2005 and2015 in China has continued to expand,and the relative differences have continued to shrink.Through the measurement of the contribution of the Theil Index to the regional disparities and the interregional disparities,it can be clearly seen that the disparity between regions is the main cause of the differences in economic growth in the seven regions of China.Therefore,narrowing the differences in economic growth among the seven regions is an important task for China to reduce regional economic growth differences.The empirical analysis results show that five factors such as industrial concentration,government support,innovation level,material capital,and human capital all passed the test of significance,which has a significant impact on economic growth.This provides the basis for policy formulation.Therefore,in the formulation of policies,appropriate development paths should be adopted in line with local conditions;at the same time,guidance should be strengthened to formulate active industrial policies;and innovation should be promoted to promote industrial upgrading;and education should be promoted to raise the level of human capital.
