从要素收益的视角出发,同样可以对当前国际贸易分工做出较好的解释,在构建要素收益差异与贸易分工的理论分析框架的基础上,本文提出比较收益原理,即一个国家和地区倾向于更多出口要素相对收益率较高的产品。通过对贸易引力模型的改进,利用主要出口国家贸易数据进行实证检验,检验结果表明了大多数出口国家符合比较收益原理,而中国却存在“比较收益悖论”;中国存在“比较收益悖论”的主要原因在于中国大多数部门处于全球价值链下游,更多地以加工贸易的形式参与国际分工。 From the perspective of factor income, we can also make a good explanation of the current division of labor in international trade. Based on the theoretical analysis of the structural differences in income and trade division of labor, we propose to compare the principle of return, that is, a country and a region tend to More export-oriented products with higher relative returns. Through the improvement of the trade gravity model and the empirical test of the trade data of the major exporting countries, the test results show that most of the exporting countries are in line with the comparative revenue principle, while China has the “comparative revenue paradox”; and China has the comparative income Paradox "is that most of China’s departments are located in the lower reaches of the global value chain, and are more involved in the international division of labor in the form of processing trade.
