Abstract:Based on the Perspective of Factor Flow, using the structural equation model and the questionnaire survey data about 126 large and medium-sized seed enterprises in the Mid-west 8 provinces (city), this paper construct a mechanism model about innovative environment, collaborative innovation mechanism and cooperative innovation behavior, verify the indirect effect of innovative environment for science-interprise collaborative innovation in the seed industry of China. The empirical results show that the innovative environment have not directly a significant influence for the participative degree of collaborative innovation in seed enterprises, but can promote the science-interprise of seed industry to achieve collaborative innovation, and the innovative strategy synergy degree and collaborative innovation mechanism between science and interprise are proved by the surveyed data to play an intermediary role as a bridge for the driving force of innovative environment, they are the direct cause to influence for the participative degree of collaborative innovation in seed enterprises. It is also found that they have some deeperly conductive mechanisms that the insurance service has a significant effect on the incentive mechanism of both parties, and the sharing mechanism of resource has a significant impact on the choice of cooperative mode between science and interprise; Moreover, the coordinative degree of technological innovation strategy has a significant effect on the choice of cooperative mode between two sides.
