中国西部生态脆弱区产业结构调整的污染风险分析——以青海省为例
Industrial Restructuring and Its Pollution Risk Analysis for the Ecological Fragile Region of West China: A Case Study in Qinghai Province
摘要
Abstract
Industrial restructuring has become widely recognized for economic growth, and it is also an effective way to promote economic growth. As one of the significant provinces in West China, Qinghai has not only a relatively backward economy, but also a fragile ecological environment. Therefore, it is of a strategic significance to study the challenges of industrial restructuring and upgrade for ecological environment management. As China' s Western Development Program continues to proceed, and Qinghai's economy develops quickly, pollutions are unceasingly on the rise. This study firstly explores the relationship between industrial structure upgrade and pollutant emissions based on the economic development-environment quality regression model. The research results indicate that there is an inverse U-shape relationship between economic growth and pollutants emissions, Qinghai province is still in the initial stage of an increasing emission of pollutants with economic growth, and there is still a long distance away from the turning point. In addition, this study analyzes the changing trend of industries with time going. Although there is on increasing trend in all of the three industries, the changes of their proportion in GDP in Qinghai are differents, among which, the proportion of the primary sector goes down all the time, while the secondary sector has a rising proportion. That of the tertiary sector shows a rising trend first, and then it goes down a little. On the basis of the above, this study estimates the proportion of GDP in each sector of Qinghai in the same sector of the whole country, and analyzes the changing trend of industrial structure from 2002 to 2007, and then applies the input-output model to estimate the pollutant emissions caused by industrial structure upgrade and adjustment, finally assesses the pollutant risk caused by industrial structure upgrade. Although proportion showing an increasing trend in Qinghai's GDP, the proportion of the primary sector in the whole country does not change remarkably, which illustrates that the growth rate of the primary sector is similar to that of the nation. The proportion of the secondary sector in the whole country falls from 2002 to 2007, while that of the tertiary sector goes up, which indicates the developing trend of industries of Qinghai province, sped up in the tertiary sector, and reduced in the secondary sector with heavy pollution. Industrial structure upgrade has different impacts on the pollution in different sectors. The research results indicate that although the development of machinery and equipment, hotels and catering services and real estate, leasing and business services has increased emssion of pollutants, it is much lower than the reduced emissions caused by many other industries. Although economic development will increase environment pollution, more pollution will grow with further economic development. However, industrial restructuring has the function in controlling waste water and waste gas emission so as to reduce the pollution risk to some extent. All of the research conclusions provide significant references for industrial restructureing, environment pollution reduction and coordinated development of economic growth and environment protection in Qinghai province.关键词
