Research On Production Decisions Of Construction Machinery Remanufacturing Enterprises Considering Carbon Emission Reduction Under Carbon Credit Financing And Mixed Financing

Recently,environmental problems have become important issues around the world,and China,as the world’s second largest economy,must shoulder the responsibilities of a major country while maintaining efficient growth.In the process of gradually implementing energy conservation and emission reduction policies,China has learned from the experience of the international carbon trading market,and officially launched the national carbon emission trading market in 2021 to explore the use of market mechanisms to control carbon emissions.For the implementers of carbon emission reduction,remanufacturing is an important means for enterprises to achieve energy saving and emission reduction,which greatly reduces carbon emissions while saving raw material consumption.As one of the key remanufacturing industries in China,construction machinery remanufacturing has been vigorously developed.XCMG and SEVALO have carried out construction machinery remanufacturing business,which provides an important way for the disposal of retired construction machinery.As one of the important policy tools to tackle climate change and innovate environmental regulation,carbon finance has been effectively implemented in Europe and other regions,and will play an increasingly important role in the process of carbon emission reduction.Carbon credit takes full account of the environmental impact of the loan project,and provides financial support for enterprises with CDM projects and energy conservation and emission reduction activities,so as to realize the flow of funds to green industries.For construction machinery enterprises that lack capital sources,carbon credit provides them with a new financing channel,which can effectively solve the problem of carbon emission reduction funds faced by enterprises.Under the carbon cap-and-trade policy,the construction machinery remanufacturing enterprise is taken as the research object and carbon credit financing is taken as the financing channel of enterprise emission reduction investment.In order to maximize the profit of enterprises,the optimization theory is used to study the production decision of enterprises.The main research work includes the following three aspects:Firstly,the production decision of construction machinery remanufacturing enterprises considering carbon emission reduction without financing is studied.For the construction machinery remanufacturing enterprises with limited capital,regardless of financing channels,the optimization model of production decision making with self-owned capital for emission reduction investment is established.The impacts of self-owned capital,emission reduction investment ratio and cost coefficient of recycling logistics of construction machinery on production decisions,carbon emissions and consumer surplus are analyzed by numerical simulation,which provides some insights for the emission reduction investment activities of enterprises.Secondly,the production decision of construction machinery remanufacturing enterprises considering carbon emission reduction under single carbon credit financing is studied.For the construction machinery remanufacturing enterprises with limited capital,considering single financing channel,the production decision optimization model of carbon credit for emission reduction investment is established.Then,the output,profit and carbon emissions are compared and analyzed with or without emission reduction investment.And the influence of each parameter on production decision-making is further analyzed through numerical simulation,which provides relevant suggestions for the government to promote the development of carbon credit.Finally,the production decision of construction machinery remanufacturing enterprises considering carbon emission reduction under the mixed financing of carbon credit and debt financing is studied.For the construction machinery remanufacturing enterprises with limited capital,the production decision optimization model of the mixed financing mode is established through the carbon credit financing for emission reduction investment and debt financing to solve production capital constraints.Then,the output,profit and carbon emissions are compared and analyzed with or without capital constraints.Furthermore,the influence of each parameter on production decision is analyzed by numerical simulation,which provides some guidance for enterprise development.
