不同主导模式下工业共生链的定价决策研究

A study of decision making in industrial symbiosis chain dominated by different rights

工业共生链管理是提高不同链之间经济效益与环境可持续发展的有效手段。为研究不同主导模式下工业共生链中各企业的定价问题,建立一个由废弃物供应商和产品制造商组成的两级工业共生链模型,采用博弈论分析方法求得不同主导模式下废弃物供应商和产品制造商的最优定价和利润模型,在此基础上进一步分析了共生程度、废弃物利用率、单位利润值对工业共生链中各方收益的影响。研究发现:不同权利结构会导致各利益主体的最优价格和最大利润不同,当制造商处于主导地位时工业共生链总收益高于供应商主导;随着共生程度和废弃物利用率的增加,工业共生链中制造商和供应商均可获得更多的利润。最后,通过算例分析,验证了结论的有效性。

Industrial symbiosis chain management is an effective means of improving economic efficiency and environmental sustainability between different chains.A two-level industrial symbiosis chain model consisting of a single supplier and a single manufacturer was developed.The Stackelberg game was used to analyze the optimal pricing and profit model for each participant under different rights dominant models of suppliers and manufacturers.The impact of the degree of symbiosis,waste utilization and unit profit value on the revenue of the industrial symbiosis chain was also analyzed.Results show that different rights dominance leads to different optimal prices and maximum profits for each player.Suppliers and manufacturers are in the lead in price and revenue decisions regardless of who dominates.The total revenue of the industrial symbiosis chain is higher when the manufacturer is dominant than when the supplier is dominant.As the degree of symbiosis and waste utilization increases,the symbiotic firms can earn more profits.The validity of the conclusions is finally verified by the analysis of arithmetic examples.
