Abstract:The innovation effort of the innovation subject is the key to improve the output level of collaborative innovation on RegTech.This paper constructs incentive mechanism and principal-agent model based on the behavioral logic of the innovator"s pursuit of maximum“Profit”, and studies the contractual incentive to promote the level of the output of the collaborative innovation of RegTech. The research shows that improving the position of R D side in collaborative innovation and the proportion of profit distribution can prompt the innovation subject who is not hard enough to narrow the gap with the innovation subject who is hard enough, and then improve the overall level of collaborative innovation output. The internal control signal, such as R D staff salary input of the innovative R D party, the market feedback signal, such as the compliance cost of the financial institution and the change of the regulatory cost of the regulatory institution, can be written into the principal-agent contract to reduce the contract risk, to encourage innovative R D side to improve the level of innovation efforts to drive other participants in collaborative innovation to improve the level of innovation efforts and increase innovation output.
