Competitive Decision Policies in Supply Chains Considering Investment of Low-Carbon Technology

This paper considers a supply chain with two competitive suppliers and a retailer, in which no supplier or one of them decides to invest the low-carbon technology. Their game models are built and the comparisons are performed. The conclusions show that when one of the suppliers invests, compared with the case under no investment in low-carbon technology, although the supplier sets the higher wholesale price and the retailer also correspondingly makes a higher sales price, he also wins the higher profit, and the other supplier and the retailer accordingly achieve more profits as the free riders.
