Abstract:The construction of the platform support system for the diversified investment mechanism of disruptive innovation in China needs to be improved, so it is necessary to deeply study the benefit distribution and government subsidy mechanism applicable to the diversified investment of disruptive technology. Among them, fair profit distribution and rational incentive mechanism are the key factors to promote the effectiveness of multiple input of disruptive technologies. Therefore, in view of issues such as benefit distribution and incentive mechanism design of diversified input of disruptive technologies, cooperative and non-cooperative game is adopted to analyze the behaviors of various participants in diversified input of disruptive technologies, introduce risk factors to discuss the situation under the leadership of different actors, and further study the impact of government subsidies on the enthusiasm of various actors. Then to clarify the diversified investment incentive mechanism scheme choice. The results show that there will be insufficient enthusiasm for innovation investment in the process of diversified investment in disruptive innovation, which is due to the consideration of maximizing their own interests; When the government takes the lead, the overall disruptive technology investment cooperation has higher returns than the cooperation led by other entities. Taking the form of government subsidies under the leadership of the government can effectively stimulate the enthusiasm of various disruptive innovation investment subjects. To this end, the government should build a diversified investment mechanism, design a reasonable benefit distribution mechanism and incentive mechanism, and set an appropriate cost subsidy limit when participating in cooperation.
