| With the deepening of China’s ecological civilization construction layout and the new economic norm,our country is about to usher in the key period of green low-carbon transition.The development of green low-carbon transition requires the participation of all stakeholders.Government is the policy maker and regulator and the enterprises are the policy direct practitioner,so it is particularly important to handle the relationship between them.However,there are many characteristics in the cold chain logistics enterprises,such as "high consumption" and "high emission",which are seriously contrary to energy-saving emission-reduction that is advocated by ecological civilization construction.Therefore,the government is required to formulate and promulgate the macro policy to provide the long-term dynamic mechanism for cold chain logistics enterprises to carry out effective carbon emission reduction activities.Based on the collections and summaries of the research status and achievements of domestic and foreign carbon regulatory policies,low carbon cold chain logistics and the game between the government and the enterprise,this paper regards carbon tax and carbon trading as the representatives of government carbon regulation policy and analyzes the influence of carbon tax and carbon trading policy on carbon emission reduction behavior of cold chain logistics enterprises.The main research contents include:1.On the basis of the evolutionary game theory,this paper constructs the game model of carbon emission reduction between government and the cold chain logistics enterprises under carbon tax policy,calculates the replicator dynamic equations of the government and the cold chain logistics enterprises and analyzes each individual stable strategies and stable conditions.Through Jacobi matrix,mixed stable strategies and stable conditions of the government and the cold chain logistics enterprises are analyzed and the phase diagram of evolutionary game system are drown.At last,the influence factors of carbon emission reduction of cold chain logistics enterprises are verified under carbon tax policy via the system dynamics and VENSIM software.2.From the feasibility and reality,the research on the carbon trading policy is divided into two types: cold chain logistics enterprises enter the carbon trading platform and do not enter the carbon trading platform.In these two cases,evolution game models are constructed between the government and the cold chain logistics enterprise,the replication dynamic equations are calculated and the equilibrium results,the stable conditions and evolution trend are analyzed.Finally,with the MATLAB software,numerical analysis of the influence factors of carbon emission reduction in cold chain logistics enterprises is conducted under carbon trading in these two cases.The results show that:1.Under carbon tax policy,these factors are key to the carbon emission reduction behavior of cold chain logistics enterprises,such as punishment of government carbon regulation,the pricing of carbon tax rate,the cost of government regulation and the initial probability of government regulation.2.Under carbon trading policy,influencing factors of carbon emission reduction behavior of cold chain logistics enterprises include: government subsidies for low carbon cold chain logistics enterprises,government image of income from low carbon power,the government excess emissions penalty for cold chain logistics enterprise,the cost to enter the carbon trading platform for cold chain logistics enterprises,the penalty for cold chain logistics enterprises which hold excess emissions and still do not enter the carbon trading platform and so on.Based on the results of the research,the following suggestions are put forward.Firstly,the government should establish a scientific and rational management mechanism on carbon tax rate and initial carbon emission quota.Secondly,the government should pay more attention to the low-carbon behavior of cold chain logistics enterprises and provide policy support and subsidies and at the same time the government imposes excess emissions penalty in a reasonable range to achieve an effective reward and punishment mechanism.Thirdly,an orderly and reliable cooperation mechanism is constructed between the government and the cold chain logistics enterprises,cold chain logistics enterprises and third party carbon trading platform(market).Finally,the government should form a green low-carbon assessment mechanism and fit the results of the green low-carbon achievements into the government performance appraisal system,and appropriately increase its share. |
