Abstract: According to Ministry of Science and Technology of the People’s Republic of China, the number of granted patents reached 723.90 billion yuan in the first half of 2019, up 23.6 percent year on year. However, in the process of patent authorization, patent infringement often occurs when there is an unreasonable patent licensing contract. As a result, the licensing of patent technology and the competition and cooperation among enterprises become complicated, which easily leads to the misalignment of decision-making incentives and performance losses of enterprises. In this context, the following questions are studied: how patent holder should choose the form of patent licensing contracts, how should brand manufacturer choose CSR investment strategies, and what impact CSR investment and asymmetric information will have on the equilibrium of the system and other issues.
