英文摘要：

In this paper we identify the different models of regional governments＇ science and technology （S＆T） investment by using cluster analysis of a sample of 31 provinces of China from 2001 to 2006. And we compare regional innovative performance influenced by local governments＇ S＆T investment among different models. The findings suggest that in firm oriented model, governments＇ S＆T investment brings about more technological innovation, while in public institution oriented model, governments＇ S＆T investment creates more knowledge innovation. Finally, we make a summary of the research findings, theoretical contributions, and policy implications for the study.
