Abstract

Industrial sectors have resulted in a large amount of pollution. Environmental degradation problem requires more indepth research on relationships between different sectors' economic output and pollutant emissions. This paper analyzes the relationship between industrial economy and ecology. On the basis of it, the driving factors of industrial sectors' pollution emissions are analyzed. Firstly, decoupling elasticity of industrial sectors in Jiangsu province during 2004-2013 is analyzed by Tapio decoupling model. And then, the industrial sectors are classified into three types according to the different decoupling elasticity. Finally, the three types of industrial sectors' driving factors of industrial solid waste output are decomposed by LMDI method. The results show that: industrial sectors in Jiangsu province are divided into strong decoupling sectors, weak decoupling sectors and expansive negative decoupling sectors; economic development significantly promotes the increase of industrial solid waste output of all sectors; technology improvement and industrial structure largely decrease industrial solid waste output of strong decoupling sectors and weak decoupling sectors; however, technology improvement accelerates industrial solid waste output of expansive negative decoupling sectors; the role of industrial structure factor changes from restraint to promotion of expansive negative decoupling sectors.

江苏省工业生态系统的脱钩与驱动因素研究

工业部门造成了大量的污染。环境恶化问题需要更深入地研究不同部门的经济产出与污染物排放之间的关系。本文分析了工业经济与生态的关系。在此基础上，分析了工业部门污染排放的驱动因素。首先，采用Tapio解耦模型分析了2004-2013年江苏省工业部门的解耦弹性。然后，根据不同的脱钩弹性，将工业部门划分为三类。最后，利用LMDI方法对三类工业部门的工业固体废物产出驱动因素进行了分解。结果表明:江苏省工业部门分为强脱钩部门、弱脱钩部门和扩张性负脱钩部门;经济发展显著促进了各行业工业固体废物产生量的增加;技术进步和产业结构对强脱钩部门和弱脱钩部门的工业固体废物产生量有较大的降低作用;而技术进步加速了扩张性负脱钩行业的工业固废产出;产业结构因素的作用由抑制向促进扩张性负脱钩部门转变。
