Abstract: Under the background of the current reform on science and technology management, science and technology innovation policy evaluation has gradually become a research hot spot, receiving widespread attention from the government, innovation subjects in fields of science and technology, as well as Scientific Academia and etc. Through literature review, practice survey and case study, we found that the research achievements on science and technology innovation policy evaluation in foreign countries were pretty fruitful, and that they had certain enlightenment on our country in the perspectives of theoretical research and practical exploration of the policy evaluation framework, method and index. This paper suggested that in China, theoretical research on science and technology innovation policy evaluation lagged behind its practice, and that the faultiness on theoretical method and lack of evaluation paradigm had restrained the development of evaluation practice. Therefore, the next step of the development of science and technology innovation policy evaluation in our country should focus on strengthening the construction of evaluation theory and method system.
