突破比较优势理论中的技术不变和资源要素的不可流动性的限制,通过建立模型,用动态跨期的方法,得出结论:发达国家在贸易分配中所获得的产品份额是与它在高技术产业的初始技术水平和技术进步呈正相关的,在循环累积因果的作用下,最终导致发达国家同不发达国家经济差距的加大。 By breaking the limitation of technology in comparative advantage theory and the non-liquidity of resource elements, this paper concludes that the share of products obtained by developed countries in the distribution of trade is the same as the high The initial technological level of technological industries is positively correlated with technological progress. Under the effect of cumulative circular causes, the economic disparity between developed and underdeveloped countries will eventually increase.
