Research On The Realization Path Of "Dual Carbon" Goal In The Financial Field From The Perspective Of Multi-agent Game

The Twenty Ten Report points out that the realization of carbon neutral and carbon peak needs to be based on China’s energy resource endowment,adhere to the principle of standing before breaking,accelerate and smoothly promote a series of regular and step-by-step low-carbon actions,and then strengthen the coal fiber energy utilization in a rational and high efficiency manner,and speed up the conception and establishment of a new model of energy policy,and actively engage in the global governance of coping with climate change.All along,China has been dedicated to facilitating the creation of a equitable and high-efficient governance system for worldwide environmental change,and has been positively taking part in the world-wide administration of dealing with the issue of climate control.Nevertheless,the realization of peaking and carbon compatibility is an unprecedented challenge to achieve extensive and profound systemic changes in the economy and society.This paper first analyzes the payment matrix of enterprises,government and commercial banks based on comprehensive and perfect model assumptions,and constructs a low-carbon development evolutionary game model containing four parties: government,bank,enterprise and people.Consider that enterprises have two different strategic choices of production methods in their production and operation,namely: green low-carbon production and traditional non-low-carbon production.Then the enterprise’s unit carbon emissions will be within or outside the specified unit emission limit,and will be incentivized or penalized by the government.The government sector is divided into central government and local government,and the adoption strategy is divided into carbon emission regulation and carbon emission non-regulation.Assuming that only commercial banks exist among the financial institutions,the strategies adopted are divided into zero-carbon financial strategies and traditional financial strategies.At the same time,introducing the environmental awareness of the public,consumers will prefer the products of compliant companies for the same products.The game model of carbon development is analyzed according to the Nash equilibrium,and the evolutionary equilibrium path of carbon development under different conditions is studied by measuring the impact of different parameters on the model,such as different cost scenarios and different degrees of punishment.By using Matlab software to study the evolutionary paths and decision changes of the government,bank,enterprise and citizens,numerical simulation analysis is conducted to observe and analyze the influence of different parameters on the realization path of "double carbon" more intuitively and clearly.On top of the original model,the crucial variables of the proposed game model are modified to further explain the implications of each element on the model,to reveal the evolutionary simulation and decision changes of different game parties under different situations and paths,and to explore the results of the experimental numerical simulation of the path to achieve the "double carbon" goal.Due to the external effect of low carbon technology innovation and the business goal of enterprises and banks of "profit maximization",enterprises and banks hardly take the initiative to make "green changes" in the process of achieving the "dual carbon" goal."They are in a state of passive choice.Therefore,the strategy choice of the government and the people is divided into "top-down" policy-driven and "bottom-up"people-driven according to different driving methods.For the "top-down"policy-driven path,government departments promote technological innovation by increasing penalties,increasing incentives,and reducing regulatory costs,which makes commercial banks and other financial institutions support low-carbon development enterprises.For the "bottom-up" public-driven path,the public,by raising environmental awareness,pushes enterprises to take measures to innovate production technologies that are more conducive to achieving the "dual carbon" goal.At last,analyzing the game outcome,this study recommends establishing the low carbon spending mindset of the masses,enhancing the work of regional carbon-cutting,minimizing the expenses of corporate green innovation,boosting the sustainable expansion of zero-carbon banking and fostering the high efficiency of zero-carbon accounting and zero-carbon business,etc.It presents feasible policy recommendations for the implementation of multiple subjects to promote high-quality development,and provides Chinese vision and Chinese scheme to drive international government on the issue of environmental degradation.
