改革开放20多年以来,我国出口商品的比较优势发生了哪些变化?我国出口商品的比较优势是否符合生产要素禀赋理论?我国比较优势的变化是否遵循了巴拉萨的阶段比较优势理论?在对以上问题做实证分析时,本文把出口产品分成资源密集型产品、资本密集型产品和劳动密集型产品,并计算这三大类产品在1980年至2000年期间巴拉萨显示比较优势指数(RevealedComparativeAd鄄vantage)和净出口比率指数(NetTradeRatio)。在此基础上得出结论:我国出口商品比较优势基本上符合生产要素禀赋理论,并遵循了阶段比较优势原则。
More than 20 years since the reform and opening up, what changes have occurred in the comparative advantages of China’s export commodities? Has the comparative advantage of China’s exports complied with the factor of production endowment? Has China’s comparative advantage changed according to Balassa’s comparative advantage theory? In the empirical analysis, the paper classifies the export products into resource-intensive products, capital-intensive products and labor-intensive products, and calculates the comparative advantage index (RevealedComparativeAdventure) between the three major categories of products from 1980 to 2000, And Net Export Rate Index (NetTradeRatio). On this basis, the conclusion is drawn that the comparative advantage of our country’s export commodities basically conforms to the theory of factor endowments and follows the principle of comparative advantage in stages.
