文章在一个内生市场结构的增长模型中研究了处于不同技术差距水平的发展中国家中市场结构与技术进步之间的关系。在对发展中国家企业可利用的外溢知识的形成机制进行设定后,文章的分析表明,恰当的市场结构与发展中国家所处的不同发展阶段有关;当国内外技术差距较大时,垄断性的市场结构有利于促进发展中国家的技术进步;当技术差距较小时,垄断性的市场结构则会阻碍技术的进步;从一个较大的技术差距开始,发展中国家可以首先采取垄断性的市场结构提高其收敛的稳态知识水平;当技术差距小于临界值以后,应该采取竞争性的市场结构以提高其技术进步的速度。
In a model of the growth of endogenous market structure, the article studies the relationship between market structure and technological progress in developing countries at different levels of technological difference. After setting up the formation mechanism of spillover knowledge available to enterprises in developing countries, the analysis of the article shows that the proper market structure is related to different stages of development in developing countries. When there is a big gap between domestic and foreign technologies, the monopoly When the technology gap is small, the monopolistic market structure will hinder the progress of technology. Starting from a large technological gap, the developing countries may first take the monopoly The market structure enhances the steady-state knowledge of its convergence. When the technological gap is smaller than the critical value, a competitive market structure should be adopted to speed up its technological progress.
