Research on stability of technology innovation alliance based on the safeguard against opportunism

The contract among technology innovation alliance members is incomplete, which substantially increases the probability of members taking opportunistic behavior, resulting in great damages to the stability of the alliance. In this paper, by the method of evolutionary game theory, we divided the context of alliance into weak intellectual property protection system and strong intellectual protection system, structured a dynamic system equation of stability of technology innovation alliance based on the safeguard against opportunism, discussed its stability and concluded the significant importance of intellectual property protection to the stability of technology innovation alliance. These results may provide the theoretical basis and reference value for these enterprises which will prepare to establish or already established the alliance and seek further development.
