By taking zbj.com as the research object, combined with previous research results and enterprise research results, to build a comprehensive incentive system. This paper further focuses on the research scenarios, applies the management entropy theory to crowdsourcing, and explores the effectiveness of crowdsourcing overall incentive system to the incentive of the contractor. Based on the incentive entropy model, calculate and measure the positive entropy and negative entropy of each dimension and sub index of the performance incentive system, so as to determine the impact of each incentive factor on the overall incentive level of the performance of the package, and to measure the effectiveness and practicability of the incentive effect and the degree of coordination of the performance incentive system of the package. By measuring the incentive effect of the incentive system in time, we can control the positive entropy in time and improve the negative entropy in order to reduce the total incentive entropy. It is of great significance to encourage blind spots and dynamically maintain the coordination of incentive measures.
