内生技术进步、南北贸易与干预政策

Endogenous Technology Progress,North-South Trade and Interference Policy

文章首先回顾了内生技术进步理论,然后试图在Li(2001)、Dinopoulos和Segerstrom(2003)模型的基础上扩展Grossman和Helpman的南北贸易与产品周期模型,将北方的激进式创新行为和南方的非激进式创新行为同时纳入Dinopoulos和Segerstrom的南北贸易模型,并在内生技术进步与南北贸易框架下分析北方创新和南方模仿之间的相互作用机理,阐述政府R&D补贴、国际知识产权保护等干预政策对北方创新和南方模仿行为的经济效应。

This paper reviews the theory of endogenous technology progress and further develops the theory of north-south trade and product cycle proposed by Grossman and Helpman based on the model of Li（2001）,Dinopoulos and Segerstrom（2003）. We incorporate the radical innovation in the north and the non-radical innovation in the south together into the north -south theory of Dinopoulos and Segerstrom and analyze the inter-action between them. The paper also illustrates the economic impact of policy interference, such as government R＆D subsidies and intellectual property rights, on innovation and imitation.
