| Throughout the course of China’s reform and opening up,in the domestic relative lack of capital,technology,talent and other development factors,foreign direct investment has played a pivotal role in promoting China’s economic development.FDI has created jobs for our country,promoted economic growth and technological progress.China’s scale of attracting foreign investment has been on the rise.In recent years,it once reached the first place in the world,and the amount of foreign investment accounted for one tenth of the world.On the other hand,climate warming is becoming more and more serious.In 2010,the global atmospheric CO2concentration was 387.0ppm,but in 2017,the value rose to 402.8ppm.As a big economic and populous country,China’s carbon emission was always in the forefront of the world,and in 2013,it surpassed the United States for the first time.Based on this,this paper puts forward the impact of FDI on China’s carbon emissions.First of all,through literature research,this paper finds that FDI will produce two opposite theories of"pollution haven"and"pollution aura".Secondly,the differences of research objects will have a great impact on the conclusion.Therefore,on the basis of previous studies,this paper finds out the new transmission mechanism of environmental regulation and expands the traditional theoretical framework.After perfecting the theory,this paper analyzes the situation of attracting foreign investment in China,and makes a comparison from the perspective of distribution and structure of attracting foreign investment.Then,the appropriate coefficient factor is selected to calculate China’s carbon emission level,and the use of relative indicators among regions is analyzed.On this basis,this paper do fixed effect model regression analysis on carbon emission effect of FDI in China,and use panel threshold model to verify the existence of threshold effect in environmental regulation.The conclusion of this paper is:the direct effect of FDI will worsen China’s carbon emission situation,only in the eastern region,FDI can effectively reduce emissions.In addition,environmental regulation has threshold effect,which can promote the realization of FDI emission reduction.This study puts forward the following suggestions:balance the relationship between the introduction of foreign investment and the reduction of carbon dioxide emissions,introduce high-quality foreign investment,give full play to the favorable impact of foreign direct investment on the environment and economy,to help China achieve the goal of carbon peak and carbon neutral.The government should improve the way of environmental regulation,replace the original punishment system with economic incentives,and give full play to its emission reduction effect. |
