跨国收入差距是经济增长理论关注的一个重要命题。最新的研究将跨国收入差距归因于技术变迁的内生偏向性。现有文献只研究了偏向性技术存量的跨国差异性,本文将这一命题扩展至研究偏向性技术的增长快慢所具有的跨国差异性,分析了偏向性技术变迁的两层含义:偏向性技术和偏向性技术进步之间的区别,并研究了由此所导致的经济绝对收敛和条件收敛问题。在此基础上,结合当今发达国家和发展中国家的经济现实将跨国收入差距的收敛性分为四种情况,并从偏向性技术变迁的角度对绝对收敛和条件收敛的形成原因以及工资波动的原因给出了解释,最后总结出,持续的偏向性技术进步和高效率的人力资本投入是发展中国家赶超发达国家的重要条件。 Cross-border income disparity is an important topic of economic growth theory. Recent research attributed the transnational income gap to the endogenous bias of technological change. The existing literature only studies the cross-country differences in the stock of biased technologies. This article extends this proposition to the study of transnational differences in the growth of biased technologies, and analyzes the two meanings of biased technological changes: biased technology And the biased technological progress, and studied the resulting absolute economic convergence and conditional convergence. On this basis, combining the economic reality of developed and developing countries today, the convergence of transnational income disparity is divided into four situations. From the perspective of biased technological change, the causes of absolute convergence and conditional convergence as well as wage fluctuations The reasons are given for explanation. Finally, it is concluded that continuous biased technological progress and efficient human capital input are important conditions for developing countries to catch up with developed countries.
