Research On Oligarch Matching Decision-making Of Carbon Emission Reduction Technology Investment

With environmental pollution increasing,carbon emission reduction is becoming an urgent task.This paper researches the problem of carbon emission reduction technology investment(simplify as CERTI)from self-operated and outsourced point of views based on matching-game theory.In addition,take instance of duopoly and multi-oligopoly manufacturers to accomplish this research,and the carbon trading process is considered.Concretely,from the vertical perspective of view,a match between oligo-manufacturers and suppliers who provide heterogeneous carbon emission reduction technologies(CERT),where both of them want to maximize their profits.Specifically,under self-operated,the investment intensity is a constant over oligo-manufactures,and which can affect carbon emission reduction amount.Besides,under outsourcing,the investment intensity is connected with production quantity.From the horizontal perspective,we consider production quantity as decision variable to establish duopoly and multi-oligopoly manufacturers Cournot model,respectively.Resolve the equilibrium outcomes including optimal joint production quantities,carbon emissions and investment intensity.And finally,we offer some numerical simulation experiments to verify the above argument.This paper is summarized as the following six sections.(1)Research background and purpose.Determine the topic and the idea of this article by collecting and reading a great number of literatures,ready for the following detailed research.(2)Relevant theory description.According for the topic,we search for and describe some relevant theories as the basic of the following model.(3)Symbols definition,assumption and constraints appointment.In this section,we definite some related symbols and provide assumptions to get ready for the establishment of the matching-game model.(4)Matching-game model construction.This section is the crucial section of this paper,including two perspectives:self-operated and outsourced,which study from duopoly and multi-oligopoly manufacturers,respectively,total in four models.And lastly,some numerical simulation experiments and case analyses are provided to verify the existent and steady of equilibrium matching outcomes,as well as some sensitivity analyses are also given.Compare the equilibriums of both the two cases to obtain the optimal matching outcome for oligo-manufacturers,which has significant practical significance.(5)Optimization suggestions according to the comparing results.In this section,we provide a number of optimal suggestions over the comparing results of self-operated and outsourced for oligo-manufacturers,in order to maximize their economical utility and environmental utility,simultaneously.(6)Conclusion and outlook.In total,we conclude that:Firstly,the total expected profits of oligo-supplier matching pair have positive related with CET price;Secondly,the environmental performance of oligo-manufacturer is sensitive to its technical application efficient,but not to its rival’s.Thirdly,as for oligo-manufacturer,outsourcing is more profitable than self-operating from the point view of total utility,which total in economical utility and environmental utility.In a short,the decision of outsourcing is much better.
