A Study On The Government Differential Carbon Tax And Enterprise Production Strategy Based On Evolutionary Game Theory

The industrial revolution not only brings the rapid economic development,but also intensifies the global warming phenomenon,which is harmful to the development of society and the survival of mankind.It is known that carbon dioxide in greenhouse gases has the greatest impact on climate warming,so the world will focus on the reduction of carbon dioxide emissions.The study of low carbon economy in developed countries is ahead of China and other developing countries,and has achieved remarkable results in low carbon technology research and development,new energy development and cleaner production.The most widely used market carbon emission reduction policy are carbon emissions trading and carbon tax,Sweden,Denmark,Holland,Italy and other countries have imposed a carbon tax to control carbon emissions because of the lowest cost,a single way,the effect of good emission reduction.Athough China is the largest carbon emissions between developing countrys,but actively undertake the task of reducing emissions.carbon tax as a strong emission reduction policy,will be incorporated into China’s tax system in the future,so the study of carbon tax in the context of low-carbon production behavior of enterprises is of great significance.This paper uses the evolutionary game theory,constructs the game model of government and enterprise selection strategy,explore the the changes of enterprise production behaviors with government respectively levy a carbon tax on low carbon production enterprises and a high carbon tax on non low carbon production enterprises levy a carbon tax and high carbon tax case.By constructing the differential equation and solving the replicator dynamic equation,the stability of the system evolution is obtained,and analyze the evolutionary stability of government,enterprise and system.That only enterprises in low carbon production of additional revenue income is greater than the cost,the enterprise will tend to low carbon production;the total cost of government supervision is less than tax revenues,and enterprises in low carbon production and non production of low carbon yield difference is greater than the actual investment cost,the system will evolve to the government supervision enterprises choose low carbon production a state.Finally using Matlab R2014 b numerical simulation,analysis of government regulation,subsidy system,probability differences of carbon tax rate changes impact on the system evolution,finally obtainsthe government early regulation will be higher,enterprises choose low carbon production may be greater;the smaller the government subsidy coefficient influence on enterprise production behavior;influence of carbon tax the government tax on enterprises is larger,the rate of increase more quickly,enterprises choose low carbon production faster.
