摘　要：

在借鉴传统显示性比较优势指数的基础上构建低碳国际竞争力指数，测算和比较二十国集团（G20）中16个国家1995-2009年的制造业低碳国际竞争力指数，在此基础上，用能源强度和碳强度作为环境规制的代理变量，研究环境规制及其他因素对样本国家制造业低碳国际竞争力的影响，并从环境规制替代变量和考虑内生性两个层面进行稳健性检验，实证结果表明，在短期内，严格的环境规制不利于制造业低碳国际竞争力的提升，技术创新效应还未超越成本遵循效应，波特效应还需要更长的时间才能显现。这种负向影响在发展中国家和贸易开放度较高的国家更为显著，影响更大。

Environmental Regulation and Low-carbon International Competitiveness of Manufacturing Industries:“Porter Hypothesis” Re-examination of G20 Countries

Qi Shaozhou & Xu Jia  (Wuhan University)

Abstract:Drawing on the Revealed Comparative Advantage(RCA) index,this paper has constructed low-carbon international competitiveness index,calculated and compared low-carbon international competitiveness index of manufacturing industry of sixteen G20 countries from 1995 to 2009.On this basis,this paper uses energy intensity and carbon intensity as proxies for environmental regulation,studies the impact of environmental regulation and other factors on low-carbon international competitiveness of G20 countries’ manufacturing industry and implements robustness test through two aspects,including alternative variable of environmental regulation and considering endogeneity.According to the empirical results,in the short term,strict environmental regulation is not conducive to the promotion of low-carbon international competitiveness of manufacturing industries.Technological innovation effect has not surpassed cost compliance effect and the Porter effect needs longer time to become salient.This negative impact is more pronounced and greater in developing countries and countries with higher trade openness.
