Analysis Of The Correlation Effect Of Automobile Industry In Chongqing

As an industry with capital-intensive technology,high industrial concentration and strong correlation,the automobile industry is an important indicator of the comprehensive economic strength of a country or region.Its development has become a powerful driving force for the overall economic development of the region and the country as a whole.At present,Chongqing has become an important automobile industrial production base in Southwest China,and is in a leading position in automobile production.It has an annual production capacity of 4 million vehicles.The purpose of this paper is to quantify the forward-related effects and backward-related effects of Chongqing's automobile industry based on the theory of industrial correlation.According to the size and characteristics of its correlation coefficient,this paper analyzes the influence of Chongqing's automobile industry in the economic system.This paper first gives an overview of the automotive industry and industry relevance theory,as well as an introduction to the industry correlation measurement method.Descriptive analysis of the dynamic characteristics of Chongqing's automobile industry development from the scale characteristics,enterprise structure and scientific and technological activities.Then,the data processing of the input and output tables in 2007,2012 and 2015 will be carried out to establish the input and output table of the 43 departments of Chongqing in 2015(including the automobile industry sector),and analyze the output structure and input structure of the automobile industry in Chongqing.Then based on the measurement method of input-output model,the correlation effect of automobile industry in Chongqing is analyzed.The unweighted and weighted measurement methods are mainly used to compare and analyze the size and characteristics of the correlation coefficient of automobile industry in Chongqing.Due to the import and export in the input-output table and the inflow of domestic and foreign provinces,the industrial correlation coefficient of some sectors in Chongqing's economic system is not realistic,thus affecting the measurement effect of the automobile industry in Chongqing,so the establishment of the non-competition of the 43 departments in Chongqing in 2015 The input-output table eliminates the impact of imports and domestic inflows.Finally,the method of virtual elimination(HEM)is used to analyze the correlation effect of the automobile industry from the change of output scale.The research shows that the automobile industry in Chongqing mainly focuses on providing living materials,and its development is more dependent on the final demand.It has the characteristics of low added value and high driving ability,and the effect on product demand of other industrial sectors is higher than the value increase.Capacity;and the automobile industry in Chongqing promotes the upstream industry,and provides industries for the manufacture and production of raw materials and parts for metal smelting and rolling products,general equipment,chemical products,metal products machinery and equipment repair services.The department has a very obvious demand for pulling;it also promotes the downstream industries,such as transportation,warehousing and postal services,which have greater demand for the output of the automobile industry.
