传统贸易理论并未把碳要素作为生产要素加以考虑,而随着碳排放所带来的环境污染问题日益严峻,碳要素成为一项不可忽视的成本影响着一国在国际贸易中的比较优势。基于传统贸易模型引入碳要素变量的推论结果显示:若一国单方面实行碳要素成本内部化,将降低其碳密集型产品的比较优势,提高非碳密集型产品的比较优势。显性比较优势指数与碳要素密集度数据显示出同样的变化趋势。进一步的实证检验验证了我国实行碳要素成本内部化后将会降低食品、燃料、钢铁、化学品、纺织品和服装等碳密集型产品的比较优势,而提高机械和运输设备、办公和电信设备及汽车产品等非碳密集型产品的比较优势。总体判断,碳要素成本内部化将提高我国出口产品比较优势。
The traditional trade theory does not take the carbon factor as the factor of production, and as the environmental pollution brought by the carbon emission becomes more and more serious, the carbon cost becomes an unneglectable cost that affects the comparative advantage of a country in international trade. Corollary results based on the introduction of the carbon elemental variables based on the traditional trade model show that if a country unilaterally implements internal carbon cost, it will reduce the comparative advantages of its carbon-intensive products and increase the comparative advantages of non-carbon-intensive products. Dominant index of comparative advantage and carbon concentration data showed the same trend. Further empirical tests verify that the internalization of carbon cost in China will reduce the comparative advantage of carbon-intensive products such as food, fuel, steel, chemicals, textiles and apparel while improving the mechanical and transportation equipment, office and telecommunication equipment and Automobile products and other non-carbon-intensive products, the comparative advantage. In general, the internalization of carbon factor costs will increase the comparative advantage of China’s export products.
