A Study On The Effect Of R&D To The Automobile Manufacturing Industry TFP Growth Of Guangxi Province

After about fifty years of development,the automobile industry in Guangxi has made remarkable achievements in production and marketing.Guangxi has become an important base of producing automobiles in China,and the automobile industry has also become one of the pillar industries in Guangxi.However,there still existed some problems in the process of development,especially in the following two aspects.For one thing,the past developing mode mainly relied on the high capital and low-end labor investment followed by the severe energy consumption and the environmental pollution issues.Therefore,it's hard to continue to adopt this mode with the increase of the price of raw material and labor resource as well as the increasing public concentration to the ecological environment.For another,owing to the weak independent innovative capabilities,lack of key technologies and R&D personnel,products mainly dominated in the low-end markets,which have become the obstacles of making Guangxi automobile industry stronger and larger.Therefore,in order to make further progress,it is necessary for the automobile industry in Guangxi to reexamine the development model and promote the transformation and upgrading of technological progress.The progress of technology is the promotion of total factor productivity,that is,to get higher output with lower investment.Theoretical research shows that R&D input can promote knowledge accumulation and contribute to the promotion of total factor productivity.This paper aims to study the impact of R&D investment on total factor productivity in Guangxi automobile industry,hoping to get some inspiration from it,and provide suggestions for Guangxi automotive transformation and upgrading,and also provide reference for other provinces and cities in China.This paper firstly analyzes the present situation of domestic and foreign scholars,and then sort out the theory of technological innovation,human capital theory and economic growth theory.Based on these theories,it is to explore the development of R&D investment and total factor productivity in Guangxi automobile industry.In the empirical analysis,it firstly constructs the Solow model,estimates Guangxi automotive industry TFP,and then constructs Douglas production function model,estimates the output elasticity of R&D investment of total factor productivity,then construct the vector auto regression model,dynamically analyzes how R&D investment in Guangxi automobile industry influences the total factor productivity.The results show that Guangxi automobile industry TFP tended to grow from the year 2000 to 2016,the average growth rate is 4.11%;the investment of research and R&D personnel can promote the total factor productivity;the output elasticity of capital stock is 0.211 while the output elasticity of R&D personnel is 0.166;dynamic analysis of vector auto-regression shows that R&D investments effect on total factor productivity is a continuous process in which R&D expenditures on TFP promote stable and longer duration,R&D personnel on TFP push in the first four periods is more obvious;in addition,TFP has an obvious self-reinforcing effect and the total factor productivity will promote high productivity and sustainable development in Guangxi automobile industry.Finally,according to the research findings,specific countermeasures and suggestions for the development of Guangxi automobile industry are put forward: first,to increase R&D investment;second,to build R&D team;third,to create a good R&D environment.
