制度质量与国际R&D溢出

Institutional Quality and R&D Spillovers:Evidence from Cross-country Data

以往关于国际R&D溢出的研究大都忽略了制度因素的影响,为弥补这一不足,本文根据Coe和Helpman的国际R&D溢出模型,推导了包含制度变量的扩展模型,采用全球60个国家1981-2006年的面板数据,就知识产权保护、营商环境、市场化经济等五类制度对国际R&D溢出的影响进行了研究。结果显示,制度对于东道国的R&D溢出有重要影响,相对于制度质量较低的国家而言,制度质量较高的国家能从国际贸易中获得更多的R&D溢出。因此,对于技术相对落后的国家而言,完善自身的制度体系或许是促进技术进步的一条有效途径。

Most previous studies have ignored the impacts of institutions on international R＆D spillovers. To compensate this defect, this paper, according to an expanded R＆D spillover model based on Coe and Helpman and using panel data of 60 countries from worldwide, examines the in- fluences of institutions on R＆D diffusion and productivity growth. The empirical results show that institutions have significant impact on R＆D spillovers. Compared with countries with low-quality in- stitutions, those with higher quality get more R＆D spillovers from G-7 countries and hence have higher productivity growth. This suggests that to achieve technological catching-up and economic growth for those countries with relative low technology, improving their own institutions system may be an effective way.
