Research on Government Regulatory of Sharing Platform Based on New Regulatory Economics

Based on the theoretical regulation of New Regulatory Economics, this paper studies the optimal regulatory contracts design of the government for the sharing platform when the information is symmetric and asymmetric, considering that the platform efforts have positive effects on both the supplier and demander of resources. Through research, it is found that under symmetric information, the sharing platform will exert its best efforts but cannot obtain information rent, and can only obtain reservation utility. Under asymmetric information, the high-tech sharing platform will obtain efficient efforts and strict positive rent, while the low-tech sharing platform will only obtain reservation utility due to insufficient efforts. At this time, the rent obtained by the high-tech sharing platform is a function of the low-tech platform's effort.
