Abstract: At present, the theoretical research on innovation ecosystem (innovation 3.0) has made some achievements. It is urgent for empirical research to further explore and test the ideas put forward in the theoretical research. It is also an effective measure to guide the construction of innovation ecosystem and optimize the third generation innovation policy. Starting from the innovation policy, this paper studies the ideas, methods and indicators of innovation ecosystem evaluation, and constructs an innovation ecosystem evaluation index system including three dimensions: dynamic evolution, sustainable innovation and openness, by selecting the data of high-tech industry in China from 2007 to 2016 for empirical evaluation.
The findings are as follows: first, the innovation ecosystem of China′s high-tech industry has a large growth space, which also proves that the current innovation policy needs to be transformed. Second, in recent years, China′s innovation policies have achieved good results in promoting the population structure of high-tech industries, but at present, the collaborative innovation among populations is still lack of power. Third, we have made some achievements in promoting the transformation of scientific and technological achievements, but we still need to adjust policies to improve the proportion of innovation input and output, and we should pursue more extensive system openness in the future. Fourth, innovation policy should focus on promoting the coordinated development of innovation ecosystem in dynamic evolution, sustainable innovation and openness, so as to avoid the abnormal development of innovation ecosystem caused by excessive guidance.
According to the results of empirical analysis, this paper puts forward the following policy recommendations for the development of innovation ecosystem of high-tech industry. First, continue to give play to the guiding role of the government and accelerate the transformation to the third generation innovation policy. Pay attention to the coordinated development of the dynamic evolution, sustainable innovation and system openness of the innovation ecosystem of high-tech industry, gradually form the innovation policy system conducive to the development of the ecosystem of high-tech industry, and guide the reasonable development of the industry.
Second, in the environmental policy, we should focus on promoting the cooperation policy of industry, university and research, increase the power for the cooperation of innovation population, build a policy system conducive to the overall competitiveness of innovation ecosystem, distinguish the functions and tasks of basic research, applied research, development research and other links, so that the contributions of each link are mutually supported and the division of labor is relatively clear, which cannot simply require all of the scientific research is application-oriented. 
Third, in the supply side policy, we should integrate scientific and technological resources, continue to promote the transformation of innovative achievements, enhance the protection of innovative achievements, continue to support the development of scientific and technological intermediaries, and create a good environment for the operation of innovation ecosystem.
Fourth, in the demand side policy, we should focus on adjusting the investment structure and building a multi-channel and multi-level investment mechanism for high-tech industry. Financial support should reflect the dominant position of enterprises in technological innovation. In addition to the advantages of large-scale high-tech enterprises, it should also pay attention to small and medium-sized enterprises with development potential, and provide them with certain financing platform and policy welfare.
