Abstract:With the series of policies to encourage university teachers to start their own businesses in their posts, how to balance the relationship between academic and entrepreneurial, and how to realize the social service through scientific and technological innovation in universities is a difficult problem faced by many academic entrepreneurs. In this regard, taking the award-winning projects of China “Internet + ” College Students Innovation and Entrepreneurship Competition as the case base, using grounded theory research method, in-depth interviews were conducted with a number of academic entrepreneurs who had been starting their own business for more than three years. This article uses semi-structured interview to collect data, consult and collect the public information of relevant universities and regions, then makes a multi-case comparative analysis, and constructs a theoretical model of the dual identity integration of academic entrepreneurs affecting firm performance. The results show that the dual identity integration of academic entrepreneurs realizes the innovation of business model through the choice of entrepreneurial orientation, market orientation and technology orientation, and then influences the firm performance. In this process, the perception of the external entrepreneurial environment and their own internal career adaptability play a moderating role. Therefore, the integration of dual identities of academic entrepreneurs is conducive to promoting the transformation of scientific and technological achievements and achieving the success of academic entrepreneurship. In view of the limitations of grounded theory, it is necessary to use quantitative research method to test the model.
