Research on Product Quality Information Transmission in Supply Chain with Social Responsibility

This paper constructs a supply chain decision model involving manufacturers, retailers and consumers. Manufacturers have private information about product quality, which is expressed by corporate social responsibility (CSR) behavior. This paper discusses the feasibility of indirectly transmitting upstream quality signal mechanism through CSR behavior by manufacturers on the basis of retailers' CSR awareness, describes the separation equilibrium, and further analyzes the differences in strategy and performance of supply chain members under different circumstances. The results show that manufacturers can transmit their own quality information through a certain level of CSR behavior. Retailers' strategies under symmetric information and asymmetric information are exactly the same, and they don't have the motivation to raise their awareness of social responsibility. However, H-type manufacturers will implement higher corporate social responsibility behaviors under asymmetric information, so profits will be lost.
