Abstract: Innovation-driven development has become a consensus among people. According to the theory of endogenous growth, endogenous technological innovation is fundamental to a country’s economic development and national competitiveness. However, people’s opinions vary greatly on how to drive innovation and there are even some misunderstandings. The debate between the circles of economics and management, in essence, is also a typical manifestation of the puzzle. Based on the available literature and open innovation theory, this paper constructs the "Seven Power Model", which aims at technological innovation power source. This Paper also proves that the internal force, the customer pull force, the supplier driving force, the collaborative force between universities and research institutes, government policy incentive force and the science and technology intermediary service force all have a positive effect on innovation performance. Besides, the government incentive force and the science and technology intermediary force have a positive regulating effect on the other driving forces.
