Study On The Economic Growth Effect And Agglomeration Cause Of The Third Industry Agglomeration In Sichuan Province

The concentration of industries in specific geographic locations is an important feature of economic activities.In recent years,industrial agglomeration has become a hot topic in domestic academic circles.Research focuses on secondary industries,especially manufacturing.The development status of the tertiary industry is an important criterion for measuring the development level of a country or an economy.Compared with the secondary industry,the tertiary industry has the advantages of low investment,low pollution,high added value,and strong employment,and promotes the development of the tertiary industry.It is an inevitable requirement to increase productivity and improve the people's lives.Sichuan Province,as a major province of the western economy,has a tertiary industry development level that is crucial for improving regional economic growth and people's living standards.This paper uses the data of the third industry of 21 cities and counties in Sichuan Province from 2007 to 2016 as a sample to build the surface data,select the GDP growth rate as the explanatory variable,the city's tertiary industry concentration degree as the explanatory variable,the degree of government intervention,the investment quota,The employment of labor and the population growth rate are the control variables.The relationship between the concentration degree of tertiary industry and regional economic growth is studied.The degree of tertiary industry concentration is calculated by location entropy.At the same time,taking Sichuan Province's 1998-2016 data as a sample,the number of employees in the tertiary industry in Sichuan Province was selected as the explanatory variable.The economic development level,infrastructure construction,urbanization level,human capital,financial development level,and fiscal expenditure were the explanatory variables.To explore the cause of the agglomeration of tertiary industries in Sichuan Province.The following results were obtained: From 2007 to 2016,the overall growth rate of the tertiary industry output in cities and counties in Sichuan Province was relatively fast,but there was a large gap between cities and counties.On the whole,the average growth rate during the 10-year period basically exceeded 10%,and from 2014,the growth rate of the tertiary industry in most prefectures and cities was faster than that of the regional GDP;the ratio of the tertiary industry's output value to the GDP was low as of 2016.20 cities and states did not reach 40%,far below the national average of 51.6%.The concentration degree of the tertiary industry shows a downward trend,and the degree of aggregation is not high.Therefore,the development of the tertiary industry in Sichuan Province is relatively backward,lagging behind the country.The concentration degree of tertiary industry in cities and counties in Sichuan province has a significant positive effect on regional economic growth,and there is an inverted "U" type relationship.The coefficient of concentration of the tertiary industry is 19.66,which indicates that industrial agglomeration has a significant impact on Sichuan's economic growth,and the coefficient of squareness of the degree of aggregation is-5.85,indicating that the tertiary industry clustering in Sichuan Province has a significant positive effect on economic growth in the early period,but From the late development stage,the degree of concentration of the tertiary industry has an adverse effect on economic growth.From the perspective of control variables,government intervention has a significant negative impact on economic growth and has an adverse effect on the economy;investment quotas have a significant positive effect on economic growth;labor employment and population growth have no significant effect on economic growth.The six variables of economic development level,infrastructure construction,urbanization level,human capital,financial development level,and fiscal expenditure all have a positive impact on Sichuan's tertiary industry agglomeration.Among them,the urbanization level has the most significant impact.Under the other factors unchanged,a 1% increase in urbanization level will result in an increase of 0.1478% in the concentration of the tertiary industry,and a 1% increase in the human capital will increase the tertiary industry accumulation by 0.0706%.The level of economic development,fiscal expenditure,infrastructure construction,and financial development each increased by 1%,and tertiary industry agglomeration increased by 0.0171%,0.0166%,0.0124%,and 0.01029%,respectively.
