Abstract: To analyse the characteristics and tendency of China's enterprise innovation, we carried on a questionnaire survey of the whole samples of national innovative enterprises. Then we wrote three reports based on the survey. This paper is one the reports. We found that the market demand has become the main motivation of enterprise innovation. The second motivation is the promotion of technology. The motivation from policy orientation and policy support is lower than technology promotion, but it is the important reason for enterprise innovation and has big influence on industries such as chemical industry, equipment manufacturing, etc. This paper proposes some suggestions on policy development meeting the market demand.
