Abstract:Whether from the perspectives of innovation ecosystem can identify the key factors that lead to innovation "blind spots", and effectively avoid it is the key to success, the existing research for the construction of recognition index system and evaluation of innovation "blind spots" exists a big gap. In this paper, by constructing the identification index system of innovation "blind spots" , with China rail transit equipment industry as the research object (north and south car "China star" and CRH380A data samples), the multi-level fuzzy comprehensive evaluation method is adopted to empirical testing index system of innovation "blind spots". The research results show that the innovation "blind spot" mainly lies in the uncoupling of innovation environment, government departments, suppliers, core enterprises, complementary suppliers and users/purchasers. The identification index system of innovation "blind spot" is credibility.
