Optimal financing strategy in a closed-loop supply chain for construction machinery remanufacturing with emissions abatement

Motivated by the remanufacturing practice of construction machinery, this paper examines the impacts of different cooperation financing and carbon emission reduction (CER) strategies on the operational decisions in a closed-loop supply chain (CLSC) where the original equipment manufacturer (OEM) produces only new products and the capital-constraint retailer produces remanufactured products and sells both new and remanufactured products to consumers. Based on the cooperation level between the OEM and the retailer, four different financing strategies, including the non-cooperation financing (NCF), the supply chain carbon financing (SCCF), the partial cooperation with delay-in-payment financing (PCD), and the full-cooperation financing (FC), are explored. Meanwhile, we extend the proposed models by considering the CER strategy implemented by the OEM, and then investigate its impact on the optimal operational and financing decisions of the retailer. The results show that: i) Under different financing strategies, the CER strategy has no impact on the retail price of remanufactured products, but can help increase the market share of new products and strengthen the market value effect for the OEM. ii) Compared with the scenario without CER, the SCCF strategy can not only ease funding pressure than the NCF strategy for the retailer but also increase the CLSC profit under the CER strategy. iii) No matter which financing strategy is adopted, the CER strategy always has a squeezing effect on the market size of remanufactured products, i.e., the cannibalization effect. iv) The CER strategy is not conducive to the development of the re manufacturing industry, but can improve the environmental performance in terms of reducing emissions and increasing the market sales for new products.
