| With the rapid development of the aviation industry,greenhouse gas emissions from aviation are growing rapidly.In order to control carbon emissions from the aviation industry,the International Civil Aviation Organization has proposed Carbon Offsetting and Reduction Scheme for the air transport industry,with the goal of achieving carbon neutral growth in the aviation industry from 2020.Although international organizations have formulated relevant policies,specific implementation methods and carbon quotas have not yet been decided,which has caused certain difficulties in the implementation of the policies.In this context,research on the allocation of carbon emissions in the aviation industry is of great significance for achieving carbon neutrality The studies on resource allocation have been based on the assumption that each allocation object,the decision-making unit,is completely homogeneous.Airlines choose the appropriate technology to combine labor and capital to obtain benefits,but the production frontiers of different companies are not actually the same,the production technology frontiers are heterogeneous,due to their different location conditions,resource endowment,market environment,policy orientation,etc.Therefore,this paper first explores the problem of carbon emission allocation in the aviation industry considering heterogeneity.Airline alliances are an international cooperative organizational structure formed by airlines in response to competitive pressures in aviation industry.Airline alliances have far-reaching impacts on airlines,it is important to consider the cooperation among alliances to reduce emissions when considering carbon emission allocation,which may lead to new adjustment to carbon emission allocation methods.Solving this problem can help the aviation industry achieve the carbon neutral 2020 goal and provide theoretical support for the subsequent establishment of a carbon trading market in the aviation industry.The research in this paper mainly covers two issues:the allocation of carbon emissions based on the meta-frontier of equity and efficiency,and the allocation of carbon emissions based on the cooperative emission reduction of alliances.This paper firstly investigates the meta-frontier carbon emission allocation based on equity and efficiency,analyzes the technological heterogeneity of airlines,measures the efficiency using the meta-frontier data envelope model(DEA)based on the non-convex assumption,and reallocates carbon quotas based on the measured efficiency combined with the zero-sum DEA model.There is a difference between the DEA efficiencies of the meta-frontier measured under the convex and non-convex assumptions due to the bias of the meta-frontier efficiency measured under the convexity assumption.The zerosum DEA allocation method based on the nonconvex meta-frontier utperforms the grandfathered method allocation in terms of both equity and efficiency.Secondly,this paper studies the carbon emission allocation based on the cooperation of airline alliances.The Shapley value method is used to allocate carbon quotas to each airline alliance based on the change of carbon productivity growth brought about by the cooperation,then the carbon quotas of companies within the alliance are reallocated using the zero-sum DEA model based on the non-convex meta-frontier efficiency.After the Shapley value method considered alliance cooperation,the carbon quota ratios of the three major alliances varied significantly.The Star Alliance and the Oneworld Alliance dominate the benefits of cooperation enhancement and therefore also receive a larger proportion of carbon quotas.From the perspective of the overall control of carbon emissions in the aviation industry,a two-stage allocation scheme can not only ensure that carbon dioxide emissions remain unchanged,but also redistribute emissions among alliances,which can stimulate the alliance’s awareness of cooperation and improve production potential,so as to realize the aviation industry.overall benefit. |
