Impact of Information Asymmetry on the Operation of Green Closed-Loop Supply Chain under Government Regulation

Recycling subsidy and carbon tax policies are ways to achieve energy environmental sustainability. The implementation of these has changed the operating environment traditional closed-loop supply chains, while privacy relevant information increases difficulty decision-making. Under background, this paper considers green chain (GCLSC) under hybrid policy recycling where manufacturer is in charge retailer invests marketing. Taking marketing cost coefficient as retailer’s private information, explores influence asymmetry on optimal decisions performance GCLSC. By constructing game models symmetry asymmetry, decisions, economic performance, social welfare provided. Combined with numerical analysis, uncertainty manufacturer’s estimation, subsidies GCLSC proposed. results indicate that estimation can improve certain conditions, but it cannot reduce emissions. oppositely affect Information beneficial retailer. However, less not always better for manufacturer. needs proactively adopt strategies stimulate sharing.
