摘要:

商业银行作为支持化工行业“双碳”目标达成的主要金融服务主体,面对化工行业“三高”特性,如何设定绿色信贷投放标准已成为“双碳”目标金融服务与支持的关键。因此,本文从绿色信贷主从博弈交叉视角出发,考虑政府制定的碳交易标准,构建了在碳配额交易政策下商业银行与化工企业信贷行为Stackelberg博弈模型,并借助理论分析和数值模拟深入探究了碳交易价格、碳配额标准和绿色信贷政策对化工企业低碳行为最优决策的影响机制。研究结果表明:(1)碳交易价格高于某一临界值时,化工企业实施严格碳排放策略并积极在碳交易市场上进行交易进而获得较高的利润,且此时商业银行利润也有所增长,符合政府的绿色规划标准;(2)碳排放配额过低或过高都不利于化工企业积极进行绿色技术创新,过高时,化工企业更愿意在碳交易市场上购买碳配额;(3)在碳交易价格和碳排放配额的共同作用下,碳价较高时,碳排放配额高于某一临界值会给严格减排的化工企业带来更多的利润,商业银行也更愿意给予绿色信贷,社会总福利达到最优。本研究丰富了有关化工企业与商业银行在碳交易政策下的博弈成果,同时,也为政府制定合理的碳交易价格和碳排放配额提供一定理论参考。

Abstract:

As countries around the world attach importance to low-carbon economy, in order to effectively reduce carbon emissions, governments have implemented a variety of carbon policies including carbon tax, carbon trading market mechanism and low-carbon subsidies, and established a carbon emissions trading market. Carbon dioxide and other greenhouse gases are the main causes of global warming, and the chemical industry has a significant high energy consumption, high pollution, high carbon emissions of the “three high”characteristics, so in China to carry out carbon peak, carbon neutralization action and the construction of carbon emissions trading market in the chemical industry should also be the focus of the field. As the main financial service subject supporting the “double carbon” goal of the chemical industry, commercial banks are facing the “three high” characteristics of the chemical industry. How to set the green credit delivery standard has become the key to the financial service and support of the “double carbon” goal.From the perspective of green credit master-slave game crossover, considering the carbon trading standards formulated by the government, a Stackelberg game model of credit behavior between commercial banks and chemical enterprises under the carbon quota trading policy is constructed, in which commercial banks are the leaders and chemical enterprises are followers. The optimal decisions of each decision-maker in three situations ( chemical enterprises actively reduce emissions and sell surplus carbon emission quotas, chemical enterprises negatively reduce emissions and purchase carbon emission quotas, chemical enterprises negatively reduce emissions but do not purchase carbon emission quotas ) are mainly discussed. By comparing the profit functions under different modes, the influence of carbon trading price and carbon quota standard on the behavior decision-making of chemical enterprises and commercial banks is analyzed. Finally, the influence mechanism of carbon trading price, carbon quota standard and green credit policy on the low-carbon optimal decision-making of chemical enterprises is deeply explored by numerical simulation, and the theoretical analysis part of this paper is further verified.The results show that (1)when the carbon trading price is higher than a certain critical value, chemical enterprises can obtain higher profits when they implement strict carbon emission strategies and actively trade in the carbon trading market, and the profits of commercial banks also increase at this time, which is in line with the government 's green planning standards. (2)Too low or too high carbon emission quotas are not conducive to chemical enterprises to actively carry out green technology innovation. When the carbon emission quota is too high, chemical enterprises are more willing to purchase carbon quotas in the carbon trading market.(3) Under the joint action of carbon trading price and carbon emission quota, when the carbon price is high, the carbon emission quota will bring more profits to the chemical enterprises with strict emission reduction when it is higher than a certain critical value. Commercial banks are also more willing to give green credit, and the total social welfare is optimal.
