转型期知识产权保护制度的增长效应研究

知识产权保护制度是发展中国家能否克服短期技术困境、促进经济长期增长的关键因素。本文从宏观层面研究我国知识产权保护制度对经济增长的影响机制,主要贡献在于:首先通过构建知识产权保护指数,实际测算1985—2010年中国的知识产权保护程度。其次通过构建"知识—生产"两部门理论模型,分析知识产权对经济增长的影响机制。最后基于中国转型期经验数据,运用动态建模方法实证研究我国知识产权制度对经济增长的影响。研究表明,对于处于转型期的中国而言,短期内较弱的知识产权保护程度有利于经济增长,而较强的知识产权保护程度则有碍于经济增长;在长期均衡的状态下,较强的知识产权保护程度确实可以促进经济增长。

The Effect of Intellectual Property Rights Protection System on Chinese Economic Growth during Transition Period

Intellectual property rights (IPR) protection has become a key factor that can overcome short-term technical difficulties and promote long-term economic growth in the developing countries. This paper studies the mechanism of China's IPR protection on economic growth from the macro level. First, we create a new IPR protection index and calculate the level of IPR protection in 1985—2010. Second, we analyze the mechanism of IPR protection on economic growth by building a two-sector model of knowledge production. Finally, we estimate the effect of IPR protection on economic growth by using a dynamic model and empirical data in transition. The results show that, for the current China, in the short-run, a weak level of IPR protection promotes economic growth while a strong level of IPR protection hinders economic growth; in the long-run, a strong level of IPR protection stimulates economic growth.
