Empirical Research On The Impact Of China’s Manufacturing Industry Agglomeration On Environmental Pollution

Industrial agglomeration has became the main driving force of China’s economicdevelopment through economies of scale, correlation effects and spillover effects. Butsome special industrials in this agglomeration region may impact the sustainableeconomic development; especially the negative externalities of industrialagglomeration may lead to environmental pollution. Therefore, this paper studied therelations between industrial agglomeration and environmental pollution, which wasboth for the development of industrial agglomeration, but also provided a moreobjective basis for decision making for environmental optimization.This paper attempted to analyze samples of China’s manufacturing industry, andin particular the selection of the six types of representati ve environmental indicatorsof wastewater emissions, dust emissions, smoke emissions etc. And this article builtstatic and dynamic panel data to analyze the impact of industrial agglomeration to theenvironmental from industry level. First, with the life cycle theory of industrialclustering framework for economic analysis and research, combined with theindustrial agglomeration externalities in technology, capital, and information, thisarticle explained the impact mechanism of environmental pollution and found thatindustrial agglomeration had different impact on environment pollution in differentstages. Secondly, by the description of the level of China’s manufacturing industryagglomeration, this paper discovered that concentration level of China’smanufacturing industry was in a low degree of agglomeration, but the overall trendwas upward. Followed by the description of the environmental pollution in China’smanufacturing, this paper discovered the total increasing discharge of pollutants, suchas capital-intensive industries, followed by labor-intensive industries,technology-intensive industries emissions was relatively small. But the trend showedthat the emission intensity had weakened in the next few years and China’smanufacturing environment problems eased. Finally, this paper built a econometricmodel including industrial agglomeration, technology, economy scale and otherfactors to study the effects of industrial agglomeration and other control variables onenvironmental pollution from the industry level. Then the results showed that therelationship between sulfur dioxide emissions, solid waste emissions and industrialagglomeration has crossed a turning point and did not reach the second turning pointin the N-shaped curve; there was a positive linear relationship betweenwastewater,carbon dioxide and industrial agglomeration; the relationship between dust and industrial agglomeration was N type curve; the relationship between smokeemissions and industrial agglomeration was in the anti-U-shaped region which was inthe left of the second turning point of the N-shaped curve. And currently the majorityof our manufacturing industry in China has crossed a turning point and did not reachthe second turning point in the N-shaped curve. Accordingly, the article proposeddecision-making recommendations to optimize the industrial agglomeration andreduce the level of environmental pollution.
