【摘要】 本文基于WIOD数据库刻画了2001—2009年间我国14个工业行业与全球38个主要国家间的价值链嵌入度和贸易隐含碳排放程度,并实证研究了我国全球价值链嵌入对碳排放的影响。研究发现:首先,全球价值链嵌入会显著减少工业行业的贸易隐含碳排放,但是参与价值链会加剧污染密集型行业的贸易隐含碳排放量。同时,外商直接投资并没有通过参与国际分工给中国的环境造成恶化效应,反而促进了环境的改善。此外,全球价值链嵌入对技术密集型行业的环境改善效应更强。其次,分位数回归发现随着价值链嵌入程度提高,全球价值链嵌入对环境污染的改善效应表现得更为突出。最后,全球价值链嵌入对环境的改善效应主要来源于全球价值链前向嵌入的积极作用,全球价值链后向嵌入则会提高行业的贸易隐含碳排放。也就是说,提高中国中间品间接出口的比重将有利于环境质量的改善,但国内增加值率的下降将恶化我国的环境状况。更多还原

【Abstract】 This paper measures the degree of global value chain embedment and embodied carbon in trade between China and 38 trading partners,and then does empirical research on the environmental effect of GVC’s embedment. First,we find that embedment in global value chains significantly reduces the industry’s embodied carbon in trade and the effect is larger in non-polluting intensive,high degree of foreign investment and technology intensive industries. Second,quantile regression shows that as the value chain embedded increase,the improvement effect is more prominent. Finally,the improvement effect is mainly derived from the forward linkages,while backward linkages play a negative role. In other words,improving the indirect value-added exports will be helpful for the improvement of environment,but the decrease of domestic value added in gross exports worsens the environment.更多还原
