Research On The Selection Of Low-carbon Technologies Under Different Carbon Emission Policies

In recent years,human activities have caused the rapid increase of greenhouse gas emissions such as carbon dioxide,which has caused global warming,and a series of disasters such as the ablation of icebergs have triggered a wake-up call for human survival and sustainable social development.Therefore,it is imperative for humankind to seek an effective method to ensure the sustainable development of the environment.Various governments have formulated corresponding carbon emission policies in light of their national conditions.Common carbon emission policies include carbon taxes,carbon quotas,and carbon trading.As an important subject of human economic market activity,manufacturers not only bear the responsibility brought about by climate change,but also face enormous challenges to cope with the impact of various factors on carbon emissions,including government policies and consumers' low-carbon awareness.Based on the above,this paper proposes the research subject of “selection of low-carbon technologies of manufacturers under different carbon emission policies”.The method of constructing the model is based on the perspective of low-carbon supply chain to study how manufacturers choose low-carbon technologies under different policies and how the government should guide manufacturers to choose low-carbon technologies.First of all,this paper studies the choice of low-carbon technologies for manufacturers in the context of government subsidies to consumers.The benchmark model of this chapter is a low-carbon supply chain composed of a manufacturer and a consumer.It considers the market demand function defined by the government's subsidy to consumers who purchase low-carbon products and the low-carbon awareness of consumers.It is found that in this case,only when the government subsidy is high,the manufacturer will choose low-carbon technology1.When the subsidy is low,the original technology will be selected for production.At the same time,the improvement of low-carbon awareness of consumption is more conducive to manufacturers' choice of low-carbon technologies1.Secondly,on the basis of the above-mentioned benchmark model,a government policy of carbon tax was introduced at the same time,and the choice of low-carbon technologies of manufacturers under the carbon tax policy was studied.Through model solving and numerical analysis,the conditions for subsidy,technical cost,and carbon tax levels needed for manufacturers to select low-carbon technologies are presented.It is found that when the cost of low-carbon technology is relatively small,manufacturers are more likely to select low-carbon technologies2 as the carbon tax increases;and the higher the subsidies,the easier it is to select low-carbon technologies2 as the carbon tax increases;Based on this basis,this paper further analyzes the impact of government and consumer behavior on the carbon emissions and profits of manufacturers.Finally,on the basis of the above-mentioned benchmark model,the government policy of carbon allowance and carbon trading was again introduced,and the choice of low-carbon technologies for manufacturers under the carbon quota and carbon trading policy was studied.Through the solution of the model,the conditions for subsidy,technology cost and carbon trading price for manufacturers to choose low-carbon technologies are given.Through model solving and numerical analysis,the study found that under the condition of low cost of low-carbon technology,manufacturers are more likely to choose low-carbon technologies2 as carbon trading prices rise;and the higher the subsidies,the easier it is to trade with carbon.The increase in the price of low-carbon technologies2 is chosen;on this basis,the paper further analyzes the impact of government and consumer behavior on the carbon emissions and profits of manufacturers.Through research on the above issues,it has been shown that government policies can play a very important role in guiding manufacturers to use low-carbon technologies.However,policy formulation needs to be within a reasonable and stable scope to play an effective role,and it can also increase consumers' Low carbon awareness,increase consumer preference for low-carbon products,and then achieve emission reduction targets.
