The Study On The Impact Of Fixed Asset Investment On Industrial Solid Waste Discharge

China has a long history of investing in economic development.In the many years since the new century,China’s economic growth rate has been relatively high,and the investment in fixed assets has continued to rise.In 2006,China’s total fixed asset investment exceeded 10 trillion yuan for the first time.In 2017,it has grown to64.12 trillion yuan.The average annual growth rate in the past 12 years is as high as17.64%,of which the highest growth rate in 2009 is close to 30%.2006-2017 has become a period of rapid growth of China’s fixed asset investment.Although the growth rate has slowed down in recent years,the growth rate in 2015 has fallen below10%,but it still stands at a high level in the world.Investment growth not only brought about economic development,but also brought about various environmental problems,and pollutant emissions remained high.Industrial solid waste emissions and fixed assets investment are the closest,from 1.5 billion tons in 2006 to 3.316 billion tons in 2017.The accumulation of pollutants has brought enormous pressure on the ecological environment.The empirical results of this paper shows that the fixed asset investment of the whole society has a positive positive effect on the discharge of industrial solid waste.The 1% increase in investment can cause the solid waste discharge to increase by 0.344%.Most of the existing literature study the impact of fixed asset investment or investment structure on pollutant emissions from the environmental Kuznets curve,and tend to choose carbon emissions as a proxy variable for environmental quality.There is a little literature on industrial solid waste discharge which as a proxy variable of the environment,and the existing literature does not involve subdividing fixed asset investment into three major industries,and conducting regional differences analysis based on different characteristics of the eastern,central and western regions.Based on the panel data of 69 large and medium-sized cities in China from 2005 to 2016,this paper establishes a relationship model between the two and introduces appropriate control variables to study the impact of fixed asset investment and investment structure on industrial solid waste emissions.This article verifies that the increase in total fixed asset investment causes the direction and extent of changes in industrial solid waste emissions,and this effect is differentiated in different regions.On this basis,it is trying to find out how to maximize the effect of fixed asset investment structure optimization on pollutant emission reduction through theallocation of fixed assets investment in different regions and different industries.Before conducting empirical analysis,this paper first studies the regional correlation of solid waste discharge by means of spatial measurement,in order to better carry out regional differentiation analysis and enrich the means of improving environmental quality.Correlation research found that: from the overall perspective,industrial solid waste discharge has positive auto-correlation,and the spatial agglomeration is more significant.From the perspective of sub-city research,the cities where solid waste exhibits high-high aggregation phenomenon are mainly located in Hebei、Shanxi、Henan and Shandong;the cities with low-low accumulation phenomena are mainly located in Zhejiang、Guangdong、Hunan、Fujian、Guangxi and Jiangsu.The results of the research on the correlation of solid waste are consistent with the overall environmental pollution situation in China.When conducting pollution control,regional policy linkage can maximize the role of relevant policies.On this basis,this paper establishes a quantitative analysis of the relationship between fixed asset investment and solid waste discharge.The empirical results show that the whole society’s fixed asset investment can promote the discharge of industrial solid waste,and the two show a linear relationship of simultaneous growth.Fixed asset investment in the entire society will bring environmental pressure.According to the research on the investment of the three major industries,the investment in the tertiary industry has obvious emission reduction effects;the increase in investment in the primary industry will lead to an increase in solid waste emissions;the role of investment in the secondary industry is regionally different,it can reduce pollutant emissions in the eastern region,and increase emission in the Central and western.
