国际技术外溢与中国技术进步

International Technology Spillovers and China's Technology Progress

在对CH模型进行扩展和改进的基础上,引入进口渗透率和投资开放度等变量,测度了中国进口贸易和FDI的国际技术外溢效应。实证分析表明,中国的技术进步主要来源于国内R&D投入和通过FDI渠道发生的国际技术外溢,进口贸易对我国技术进步没有明显的促进作用。

On the basis of CH model, this paper introduces two factors of import penetration rate and investment openness rate in the mea- suring model of technology spillovers and explores the extent to technology diffusion through imports and FDI in China. The empirical study of China shows that domestic R＆D investment and technology spillovers of foreign country significantly promote China＇s technology progress through FDI. The import does not promote China＇s technology progress.
