对外贸易技术效应与中国工业CO2排放绩效
Technical Effects of International Trade and Industrial CO2 Emission Performance in China
摘要
Abstract
With the expansion of international trade scale, what are the technical effects of international trade on CO2 emissions? As to the technical spillovers of international trade, which are the main channels that benefit the industrial carbon abatement? Is there a difference between the technical effects of international trade in different industries? Based on the DEA non-parameter method, this paper uses the Malmquist-Luenberger index to estimate CO2 emission performance and its decomposition indexes between 2001 and 2010 across 34 Chinese industrial sectors, and it constructs the indexes of horizontal technology spillovers from import trade and export trade, backward technology spillovers from export trade and forward technology spillovers from import trade based on the input-output tables, and then examines the technical effects of international trade on CO2 emission performance and its decomposition indexes. Results from the whole 34 industries show that, horizontal technology spillovers from export trade have obvious negative effects on the technology advancement, but horizontal technology spillovers and backward technology spillovers from export trade have significant promotion effects on the technology efficiency. Horizontal technology spillovers from import trade have obvious negative effects on the technology efficiency, while forward technology spillovers from import trade improve the technology efficiency. This paper also shows that for industrial sectors, the technical effects of export trade on the technology advancement and the technology efficiency are similar comparing the heavy industries and the light industries, however, the technical effects of export trade are different. In conclusions, it brings forward solutions as follows; Chinese government should continuously optimize the technology structure of export trade, encourage and improve localization purchase of export companies, and enlarge the proportion of the high-tech products in the import trade, in order to take full advantage of technical effects of international trade on industrial CO2 emission performance.关键词
