FDI、知识溢出与生产率增长——基于DEA方法和状态空间模型的经验研究

本文利用DEA方法对中国全要素生产率进行了测算,在此基础上建立国际知识溢出分析框架,检验了基于FDI渠道的国外知识资本对全要素生产率的溢出效应。结果表明:国内知识资本和基于FDI渠道的国外知识资本对TFP增长起到显著的促进作用;通过对TFP进行分解发现,两者对技术进步促进作用明显,对技术效率影响微弱;采用状态空间模型进一步分析发现,于FDI渠道的国外知识资本对TFP的贡献度在不断上升。

FDI, International Knowledge Spillovers and Productivity Development: An Empirical Study based on DEA Method and State Space Model

In This paper,we compute total factor productivity of China by using DEA method,then construct a framework to analyses the impact of international knowledge capital through FDI channel on TFP. Our results show that both domestic and international knowledge capital are significant sources of TFP growth. After decomposing TFP into technical efficiency and technical progress,we find that both of them promote the technical progress ,but hardly have effect on the technical efficiency. By using State Space Model,we find that international knowledge capital through FDI channel is playing an more and more important role in promoting TFP growth.
