Bank Credit Financing and Trade Credit Financing Based on Carbon Emission Trading

Bank credit financing and trade credit financing are two basic ways for small- and medium-sized enterprises to solve financial difficulties. We studied a supply chain financing (SCF) system with one capital-constrained manufacturer and one capital-rich supplier, in which manufacturers can choose bank credit financing (BCF) or trade credit financing (TCF) to solve financial difficulties. Unlike the traditional SCF, we considered the influence of the carbon emission trading mechanism, and we designed BCF and TCF models and derived the equilibrium strategies of the supply chain members under a carbon-constrained environment. The research shows that the emission reduction level of manufacturers increases with the increase in carbon emission trading price, and the output of manufacturers increases with the increase in emission reduction level of manufacturers. When the manufacturer’s emission reduction level is low, the supplier’s benefits under BCF are higher than those under TCF. There is a threshold for the manufacturer’s emission reduction level. When the emission reduction level is higher than this threshold, the manufacturer chooses BCF mode with higher benefits; on the contrary, TCF mode is more profitable.
