本文充分考虑到贸易的内生性,利用外生的地理特征为中国工业各行业的对外贸易构建了一个合适的工具变量,并运用这一工具变量结合中国1996-2007年工业各行业的面板数据研究了既定经济条件下对外贸易对中国工业CO_2排放的影响。结果表明:贸易开放度显著地减少了中国工业各行业的CO_2排放量和排放强度,“贸易得益假说”在中国是成立的。因此,在气候变化的背景下,中国不必为了减少CO_2排放而盲目去限制对外贸易。
This paper gives full consideration to the endogeneity of trade and uses exogenous geographical features to construct a suitable instrumental variable for the foreign trade of various industries in China. By using this instrumental variable and combining with the panel data of various industries in China from 1996 to 2007 The Impact of Foreign Trade on China ’s Industrial CO_2 Emissions under a Set Economic Condition. The results show that the degree of trade openness significantly reduces the CO 2 emissions and emission intensity of various industries in China, and the “trade benefit hypothesis” is established in China. Therefore, in the context of climate change, China need not blindly limit its foreign trade in order to reduce CO 2 emissions.
