大气与水环境保护约束下中国工业品出口贸易结构优化研究

Optimization of Chinese Export Structure of Industrial Products under the Constraints of Atmosphere and Water Environmental Protection

文章利用2015年的投入产出表与行业数据,计算我国工业品出口贸易的工业废气与废水的排放强度与排放量,并利用线性规划分析模型,模拟分析优化工业品出口贸易结构减少我国工业废气与废水排放量的方法与环保效益。研究结果表明:(1)废气与废水排放密集型行业产品出口在我国工业品出口贸易中的总体占比较小,这有利于保护国内大气与水环境,但部分废气与废水排放密集型行业产品的出口比重仍然较高,这不利于保护国内大气与水环境。(2)2015年,我国工业品出口行业的废气与废水排放量均很大,分别占国内工业废气与废水排放总量的22%与32%。(3)通过有针对性地调整工业品出口贸易结构,能够大量减少我国工业废气与废水排放量。

In this paper,the industrial waste gas and waste water emissions intensity produced by China's industrial exports are calculated by using the input-output table of 2015 and industry datas,and then the methods and environmental benefits of reducing the emissions of industrial waste gas and water by optimizing the exports structure of industrial products are simulated based on linear programming model.The research results are as follows:(1)The proportion of exports from the waste gas and water emissions intensive industry in China is small which is in favor of protecting China's atmosphere and water environment,but proportion of some emissions intensive industrial exports are still high which is not conducive to protect the China's atmosphere and water environment.(2)In 2015 The emissions of waste gas and waste water in China's industrial export industry are very large which account for 22%and 32%respectively of the total amount of domestic industrial waste gas and waste water.(3)By selectivity adjusting industrial exports structure,emissions of industrial waste gas and waste water can be reduced largely.
