Construction Machinery Remanufacturing Enterprises’ Production Decisions Considering Carbon Emission Reduction Under Carbon Quota Repurchase Financing

With the rapid economic development,global ecological problems are becoming increasingly serious,and greenhouse gas emission reduction has become an important issue of social development.As a big manufacturing country,China’s carbon emissions have been increasing in recent years.In order to practice the concept of national ecological civilization construction,China has proposed the goal of carbon peak and carbon neutrality.In order to help achieve carbon peak and carbon neutrality,it is imperative for the construction machinery manufacturing industry,which is treated as an energy-intensive industry in saving energy and reducing emissions.In addition,Chinese construction machinery industry also has the problem of excess industrial structure,and construction machinery has entered the stock era.As a production mode highly consistent with the concept of developing circular economy in China,remanufacturing is an important way to solve the overcapacity of retired construction machinery,and is also an important strategy to reduce the emissions.However,the development of construction machinery remanufacturing needs sufficient financial support,but some small and medium-sized remanufacturing enterprises are faced with financing difficulties and high interest,which restricts the development of construction machinery remanufacturing.Carbon quota repurchase financing is a carbon financial tool derived from the development of carbon trading market.Obtaining financing based on its own carbon assets can not only help solve the financing difficulties and high interest of construction machinery remanufacturing enterprises,but also enhance the enthusiasm and initiative of enterprises in energy conservation and carbon reduction.In this context,this paper takes capital-constrained construction machinery remanufacturing enterprises as the research object and then analyzes the impact of carbon quota repurchase financing on production decisions of enterprises while considering carbon emission reduction.The main research contents are as follows:(1)Firstly,The production decision of construction machinery remanufacturing enterprise with capital constraint is studied.Under the carbon cap-and-trade policy,production decision model of construction machinery remanufacturing enterprises with capital constraints was established,and the model was solved by K-T condition.The influence of initial capital and reverse logistics cost coefficient on decision variables and objective function is analyzed through numerical example.(2)Secondly,the production decision of construction machinery remanufacturing enterprises under carbon quota repurchase financing is studied.In the context of capital constraints,carbon quota repurchase financing is considered in this study.In order to maximize the profits of construction machinery remanufacturing enterprises,production decision model was established when considering carbon quota repurchase financing.The output of construction machinery remanufacturing enterprises with or without carbon quota repurchase financing is compared,and it highlights the influence of carbon quota repurchase financing on the production and operation of construction machinery remanufacturing enterprises.What’s more,the influence of carbon quota sales quantity and consumer preference on the optimal strategy is further analyzed through numerical example.(3)Thirdly,the production decision of construction machinery remanufacturing enterprises considering carbon emission reduction is studied.In the context of capital constraints,carbon emission reduction is considered in this study.The production decision model of construction machinery remanufacturing enterprise under carbon emission reduction was established.The output of construction machinery remanufacturing enterprise with or without carbon emission reduction is compared,and it highlights the role of carbon abatement in business operations.What’s more,the influence of initial capital,emission reduction input ratio and carbon price on output,carbon emission and profit was further analyzed through numerical example.(4)At last,the production decision of construction machinery remanufacturing enterprises considering carbon quota repurchase financing and carbon emission reduction is studied.In the context of capital constraints,both carbon quota repurchase financing and carbon emission reduction are considered in this study.The production decision model of construction machinery remanufacturing enterprise considering carbon emission reduction under carbon quota repurchase financing is constructed.Compared with the output of construction machinery remanufacturing enterprise considering single condition.It highlights the combined effect of carbon quota buy-back financing and carbon abatement on production operations.Through numerical simulation,the influence of initial capital,emission reduction input ratio and carbon emission of remanufactured products on output,carbon emission and profit is further analyzed,which provides some guidance for enterprise development and environmental protection.
