Research on carbon credit financing of SMEs based on game theory

SMEs make increasingly outstanding contributions to the real economy, and financing is the key factor to their development. Currently, credit is the main financing channel of SEMs in China, and carbon credit is an inevitable trend. On the basis of carbon credits, this paper try to establish a game model between SMEs and bank, seek an ideal game results Nash equilibrium. We find that Nash equilibrium is (taking no measures, lending) without any constraints. Obviously, it is disappointing. Thus, environmental protection bureaus should increase condemnatory strength on SMEs whose carbon reduction is substandard and the higher authority and regulator should also increase the punishment on bank in order to prevent it lend to SMEs with carbon reduction substandard. We suggest that it is necessary to eliminate conspiracy, strengthen penalties on pollution incidents and establish SMEs Union and so on.
