成本分担契约对企业减排决策的影响研究

Study on the Impact of Cost-sharing Contracts on Emission Reduction Decisions of Enterprises

为促进汽车产业企业间的合作减排,研究成本分担契约下由供应商、制造商、销售商构成的汽车产业企业的减排决策问题。将制造商作为博弈主方,将供应商、销售商作为博弈从方,构建三方合作行为决策动态演化模型,分析三方参与的演化路径与产业整体稳定策略,并结合仿真模拟分析影响三方对遵守契约意愿的因素。研究表明:随着三方合作初始意愿的增加,汽车产业整体达到平衡的速度也越快;当制造商适当降低其承担的减排成本时,三方仍表现出守约意愿,但过大地降低其承担的减排成本时会使供应商、销售商选择违约。

In order to promote the cooperative emission reduction among enterprises in the automotive industry,the problem of emission reduction decision of enterprises in the automotive industry consisting of suppliers,manufacturers and sellers under the cost-sharing contract is studied.In this paper,the manufacturer is taken as the main party of the game,the supplier and the seller are taken as the followers of the game,and the dynamic evolution model of the tripartite cooperative behavior decision is constructed.The evolutionary path of the participation of the three parties and the overall stability strategy of the industry are analyzed.The factors affecting the willingness of the three parties to comply with the contract are analyzed with simulation.The study shows that:as the initial willingness of the three parties to cooperate increases,the speed of reaching equilibrium increases;when the manufacturer appropriately reduces its share of abatement costs,the three parties still show willingness to comply with the contract,but when they reduce their share of abatement costs too much,the suppliers and sellers choose to breach the contract.
