Abstract:Aiming at the stability problem of cross-organizational technological innovation cooperation composed of multiple enterprises and universities with different types of input resources, this paper studies the internal benefit distribution mechanism of cooperation and the amount of input resources based on cooperative game theory. By constructing the benefit model of technological innovation cooperation between enterprises and universities, the influence of the amount of resources input of each organization on the benefit of cooperation is analyzed. An example is used to prove that the benefit distribution mechanism based on Shapley value method satisfies the distribution effectiveness and the rationality of the participating individuals. Under given cooperation conditions, the participating parties can simulate the cooperation situation through numerical simulation, and analyze the sensitivity of each parameter. The theoretical results are verified by numerical examples. The research results show that: (1) when the effect of cross-organizational technological innovation cooperation satisfies θo≥?2θ, organizations can benefit from cooperation; (2) the benefit distribution mechanism of Shapley value method ensures the stability of cooperation; (3) the degree of government subsidy, factor contribution coefficient, degree of synergy effect and cross-organization effect have a positive impact on cooperation benefits, while the cost coefficient has a negative impact. Therefore, in the practice of cross-organizational technological innovation cooperation, if and only if the cross-organizational effect is satisfied θo≥?2θ, enterprises or universities can choose to join the cross-cooperation, and adopt the benefit distribution mechanism of Shapley value method and pay attention to maintain close communication. At the same time, the government should provide subsidies to enterprises and universities participating in the cooperation.
