In this paper, my purpose is to test whether the government education policy and R&D expenditure policy can lead to development of patents or not. I use an idea-based growth model as the framework while treating patents as outputs to analyze patent development. I use the data of R&D intensity, patent and human capital of 30 countries in OECD from 1997 to 2006 based on panel data model to analyze their relationships. Research shows that R&D intensity and human capital produce some effects on patent development. Finally, I give some advice for government policy about improving patents.
