Remanufacturing closed-loop supply chain decision comparison under multiple carbon policies

This article constructs a closed-loop supply chain system including a single manufacturer and a single retailer and studies the optimal decision problem of enterprises under three different carbon reduction policies. Three supply chain game models were constructed to research the impact of different carbon reduction policies on the decisions of supply chain members. The results revealed that:(1) The carbon emission reduction level of the manufacturer is negatively correlated with the recycling price of used products and the abatement cost factor;(2) When the carbon trading price is equal to the tax rate, the carbon cap and trade policy is more conducive to promoting the manufacturer to improve the level of carbon emission reduction;(3) When the carbon trading price is low, mixed carbon policy is more favorable for the manufacturer to increase its carbon emission reduction. The research results of this study can provide certain suggestions for the government to implement a reasonable carbon reduction policy.
