Research On The Relationship Between My Country's Infrastructure Investment And Economic Growth

Since the reform and opening up,after many years high speed growth,China's economic development has entered a "new normal" era.In the new development context,the importance of infrastructure investment still needs to be emphasized.So from the perspective of the new era,it has new meaning and connotation to explore the relationship between China's infrastructure investment and its economic growth.Firstly,the paper theoretically explores the relationship between infrastructure investment and economic growth using the existed research results,to check out whether there is a relationship that is known as inverted U-curve.The paper then,in the aspect of empirical analysis,analyses the relationship between capital stock of infrastructure and economic growth through an empirical analysis using econometric model.Empirical analysis is used in this paper,based on the idea of constructing a quantitative regression model,to furtherly explore the relationship between China's infrastructure stock and economic growth.In the empirical analysis part,this paper believes that China's infrastructure stock has not yet reached to the perfect point.In terms of inflection points,there are large differences in the stock of infrastructure and the inflection point of the stock of infrastructure in the eastern,central and western regions of China.On this basis,the scope of the research results of this article is slightly broader,after that,the paper carries out an international comparison study,and sub-sectors of China's infrastructure development has been discussed.Finally,based on three approaches: theoretical analysis,empirical analysis,and international comparison,the paper concludes that the inverted U-shaped relationship that promotes first and then suppresses is the relationship between infrastructure investment and economic growth.China 's infrastructure investment stock has not yet reached the inflection point.In China,the infrastructure of different industries still needs structural adjustment according to the corresponding conclusions,corresponding policy recommendations are given from the aspects of improving the legal system,price formation mechanism,and investment and financing channels.
