我国出口增长的碳排放效应研究——基于产品内国际分工的视角

The Study of Carbon Emission Effect of China’s Export Trade——From the Perspective of Intra-product International Specialization

文章对Copeland和Taylor(2003)建立的均衡污染排放模型进行拓展,使其能够充分体现我国在全球生产网络中的角色具有典型的"产品内分工"以及"外资驱动"特征,并建立开放经济条件下碳排放驱动因素的计量模型。基于我国1990-2010年的时间序列数据的实证研究显示:具有"外资嵌入"和"产品内分工"特征的我国外贸出口有利于碳排放强度的降低,同时研究还显示作为环境规制水平的替代变量人均收入水平与碳排放强度呈正相关关系。

The article expands CT model （2003）so that it can reflect China＇s role in the glohal production network with typical characteristics of ＂intra-produet specialization＂ as well as ＂foreign driven＂ , and builds econometric model of carbon emissions drivers from the perspective of intra-product international specialization under open economy. Empirical studies based one time series data from 1990 to 2010 show that the export trade of China featuring ＂foreign capital embedded＂ and ＂intra-product specialization＂ contributes to reducing the intensity of carbon emission. The study also shows that the alternative variable of per capita income, which acts as environmental regulation level, has positive relationship with carbon emission intensity.
