Abstract:Using an improved stackelberg method, considering the impact of technology spillovers and product differences, a key common technology game model including market competition and R D investment is constructed, and the impact of the uncertainty of the innovation outcome on corporate cooperation strategies is analyzed, and how companies are dynamic Choose a cooperative innovation strategy to deal with this uncertainty. The research results show that: when the uncertainty is high, companies tend to choose resource cooperation strategies to obtain more external support; when the uncertainty is low, companies tend to choose market cooperation strategies to obtain more innovation benefits; the degree of technology spillover The degree of product differentiation significantly affects key common technology cooperation innovation strategies, and increasing product differentiation can effectively reduce the negative effects of technology spillovers on innovative companies.
