CSR Input and Recycling Decisions for Closed-Loop Supply Chain with Asymmetric Demand Information

In reality, there is often information asymmetry between upstream and downstream enterprises in a closed-loop supply chain (CLSC) system, which can have a profound impact on the decisions of member enterprises and the operation of the system. Under asymmetric market demand information, this study examines CSR input and recycling decision making in CLSC. Four decision-making models were developed for CLSC, and the effects of consumer sensitivity to CSR input and demand information asymmetry on CLSC optimization were studied. The results indicate that higher consumer sensitivity to CSR input enhances both CSR levels and recycling rates, benefiting both manufacturer and retailer by increasing profits. In terms of increasing CSR levels, the manufacturer achieves the best results when independently managing CSR input and recycling. However, for improving recycling rates and market demand, the retailer is more effective when responsible for CSR input, with the manufacturer handling recycling. Additionally, demand information asymmetry reduces the manufacturer's profit but may not affect the retailer's profit. The retailer-manufacturer cooperation model proves more beneficial for overall CLSC system performance compared to information symmetry.
