Research on the performance of innovation subjects in different innovation models

Innovation could be considered as one of the keys to competitive advantage and sustainable development of enterprises. The capability of independent innovation of Chinese enterprises is relatively weak, and the weakness has become the shackles of the sustainable development of China´s economy. Game theory as the theoretical basis, this study set a framework of an enterprise, cooperative enterprises, and customers´ tripartite participation in the open innovation model to analyze the performance of various innovative subjects in a different degree of innovation. This research has shown that: an enterprise´s performance is proportional to its open degree, which means the performance of an enterprise in the open innovation model is greater than that in the semi-open innovation model; the performance of an enterprise in the semi-open innovation model is greater than that in the closed innovation model.
