本文采用1998-2005年①我国工业行业数据,就贸易自由化对我国环境污染的影响进行了研究,结果表明:首先,贸易促使我国工业向更清洁的行业结构转变,这种结构的转变降低了工业污染排放水平;其次,贸易促进了我国环保技术的进步,由此产生的技术效应减少了工业各行业单位产出的污染排放,改善了环境;最后,由于出口规模扩大对环境产生的负效应远远超过正的结构和技术效应,因而贸易对环境的总效应为负。另外,研究结果也表明,“污染避难所”假说在我国不成立。
This paper uses the data of China’s industrial sector from 1998 to 2005 to study the impact of trade liberalization on China’s environmental pollution. The results show that: firstly, trade has led to the transformation of China’s industry to a cleaner industry structure, and the change of this structure has been reduced Second, the trade has promoted the progress of environmental protection technologies in our country. The resulting technical effects have reduced the pollution output per unit output of industries and improved the environment. Finally, due to the negative effect on the environment caused by the expansion of the scale of exports, Far outweighs the positive structural and technological effects and thus the total effect of trade on the environment is negative. In addition, the results also show that the “pollution sanctuary” hypothesis is not established in our country.
