Under the outsourcing and authorizing remanufacturing, the production decision for remanufacturing closed-loop supply chain (CLSC) considering government subsidies and manufacturer’s design for environment was researched. Four CLSC decision models were constructed to analyze the effects of government subsidies and environment design investment on the competition and cooperation between manufacturer and remanufacturer as well as the performance of CLSC. It shows that the manufacturer can share the government subsidies with the remanufacturer by adjusting unit remanufacturing outsourcing fee or patent licensing fee, so the different subsidy strategies of government will not affect the optimal production decision and performance of CLSC. The government subsidies and consumer acceptance degree of remanufactured products are not always conducive to increasing the manufacturer’s design level for environment, but both contribute to promoting the sale of remanufactured products. The manufacturer always has an incentive to invest in design for environment, and the remanufacturer will only be motivated to accept the environmental design solutions if it can bring more cost savings to the remanufactured product. Compared with the licensed remanufacturing, both the manufacturer and remanufacturer will gain more profits under the outsourced remanufacturing. In addition, government subsidies and environmental design may not always play a role in reducing the total environmental impact of products.
