Abstract:With the significant increase of fossil energy consumption and the ever-worsening pollution of environment, low-carbon development becomes an inevitable choice. Carbon finance can help firms alleviate the finance pressure from carbon emission reduction. This research explores two financing methods, delay-in-payment and bank loan; and two cooperation decisions, carbon emission reduction cooperation and price cooperation. Four scenarios are considered: non-cooperation, partial-cooperation delay-in-payment, supply chain carbon finance (SCCF), and full-cooperation. We discuss how firms make their pricing and carbon emission reduction decisions under different cooperative levels and financing methods. For a manufacturer-dominated supply chain, the results show that SCCF will help the small and medium enterprise seek cooperation with the monopoly manufacturer, and improve supply chain's profit compared to green loan. What's more, SCCF pattern can effectively control the total carbon emission. In addition, we extend the model to consider the retailer-dominated case. The results show that SCCF pattern can help increase the emission reduction rate of the whole supply chain. From the perspective of emission reduction efficiency, it is better for the government to promote the SCCF mode in the retailer-dominated supply chain.

Through the establishment of the leading manufacturer Stackelberg game model under asymmetric carbon information, this paper investigates the misreporting behaviors of the supply chain members and their influences on supply chain performance. Based on “Benchmarking” allocation mechanism, three policies are considered: carbon emission trading, carbon tax, and a new policy which combined carbon quota and carbon tax mechanism. The results show that, in the three models, the leader in the supply chain, even if he has advantages of carbon information, will not lie about his information. That is because the manufacturer’s misreporting behavior has no effect on supply chain members’ performance. But the retailer will lie about the information when he has carbon information advantage. The high-carbon-emission retailers under the carbon trading policy, all the retailers under the carbon tax policy, and the high-carbon-emission retailers under combined quotas and tax policy would like to understate their carbon emissions. Coordination of revenue sharing contract is studied in supply chain to induce the retailer to declare his real carbon information. Optimal contractual parameters are deduced in the three models, under which the profit of the supply chain can be maximized.
