This paper explores crowdsourcing contest which is under a fixed bonus mechanism. The purpose of crowdsourcing is to maximize the sum of bid submitted by contestant. First, we establish utility function both the contestant and the Crowdsourcing and then the optimal solutions to Stackelberg game and then analysis results show that: The increase in the number of contestants will increase the effort for the contest and then decrease; the lower the cost parameter of the contestants, the higher the expected utility; due to the limited ability of contestants, bonuses can’t infinitely motivated contestants, so as the bonus increases, crowdsourcing crowdsourcing’s expected utilities increases first and then decrease.
