Abstract:According to Cornell university, the European institute of business administration, the world intellectual property organization (WIPO), and other agencies issued the annual national innovation capability index (GII) score and ranking, the country's absolute innovation ability and relative ranking is not fixed, but generally the innovation ability fluctuation phenomenon, the emergence of "innovation" is not a small probability event. Through comparative research, the lack of innovation becomes one of the main risks of national development. At present, global economic growth is sluggish and development is uncertain. It is of great significance for national development to recognize the lack of innovation and the role of government. This paper defines "innovation weakness" through the global innovation index (GII), and tries to explore the influencing factors of the risk of "innovation weakness" and the role of government in preventing this risk by using Logit model. The author finds that the improvement of market mechanism and human capital can significantly reduce the probability of "innovation" failure. The government needs to change the traditional way of innovation support, because it is more effective to create a good institutional environment for innovation and improve human capital than to blindly expand general infrastructure construction and increase government R&D expenditure. In addition, the author further suggests: first, unswervingly deepen the reform of the national innovation governance system. Second, we need to strengthen cultural innovation and foster an inclusive and friendly social environment. Third, we should put people first and build a talent system with vitality and creativity.
