本文将企业合作技术创新分成两类,即企业之间存在合作的创新和企业之间不存在合作的创新,并分别构造了它们的得益矩阵及其演化博弈模型.通过参数变化、相位图和数值仿真,对企业合作创新策略选择进行演化博弈分析,结果表明,与大学合作的净得益是决定企业合作创新策略的关键因素;投资额、双方得益比例和博弈双方合作历史也明显影响合作创新策略的选择;双方得益比例相等时,博弈双方合作可能性最大,比例悬殊会导致双方不合作.
It divided cooperative innovation of firms into two categories: cooperation or noncooperation between firms, and the payoff matrix and evolutionary game models were built. The strategy of cooperative innovation of firms was analyzed through the evolutionary game by the parameter variation, phase diagram and numerical simulation. The results indicate that the key factor for choosing the strategy of cooperative innovation is the cooperative profit with university-industry collaboration ; investment, profit ratio of two parties, and cooperative history of both sides can influence the choice of the strategy of cooperative innovation. When the profit ratios of two parties are equal, the probability of cooperation between the two sides is the most, while great disparity leads to noncooperation.
