【摘要】 政府补贴是促进企业再制造发展的有效手段,同时消费者行为对新产品和再制造产品的市场需求产生影响,重塑闭环供应链均衡状态。本文以ZL水泥企业为例,考虑政府补贴,将消费者行为引入闭环供应链网络,理论上拓展了闭环供应链网络均衡模型,实践上可为政府部门制定补贴政策和企业生产优化决策提供参考。本文主要的研究工作是:(1)考虑消费者低碳偏好,运用变分不等式方法,建立政府补贴下利润最大化和碳排放最小化的闭环供应链网络均衡模型,发现一定区间内的政府补贴与消费者低碳偏好均有助于提升再制造产品销售额,改善环境绩效。本文将消费者低碳偏好引入闭环供应链网络,研究经济目标和环境目标下的闭环供应链均衡决策问题,既有文献大多仅考虑新产品与再制造产品的价格差异。采用ZL水泥企业实例数据,验证文中模型和算法。研究结果表明:政府将补贴适度控制在(0,20]元/吨区间内,可在提高再制造产品市场份额和企业再制造积极性的同时将碳排放控制在较低水平。同时发现,消费者低碳偏好有助于增长再制造产品对新产品的挤兑效应,降低闭环供应链网络的碳排放量,但也导致闭环供应链网络利润降低。(2)考虑消费者感知价值,采用变分不等式方法,构建政府补贴下以利润和碳排放为目标的闭环供应链网络均衡模型,发现补贴在一定区间内有助于提升再制造产品的市场份额,实现碳减排并使企业利润损失较小,同时消费者感知价值各维度对闭环供应链网络的经济目标和碳排放目标影响各不相同。本文考虑由消费者感知价格、感知使用寿命和感知低碳水平构成的消费者感知价值,并将市场需求环境拓展至不确定情形,构建闭环供应链网络均衡模型,现有研究忽视新产品与再制造产品在感知使用寿命和感知低碳水平方面的异质性。使用ZL水泥企业案例数据,对文中模型和算法进行验证。研究表明:政府补贴在(0,5]元/吨范围内,可在保证较高经济效益的同时显著提高再制造产品的市场份额,改善环境绩效;此外,较高的再制造产品的消费者感知价格、感知使用寿命以及感知低碳水平可提升再制造产品销售额,前两者较高有利于改善闭环供应链网络的环境绩效,但导致经济绩效降低,后者较高不利于改善环境绩效,却可提升经济效益。更多还原

【Abstract】 Government subsidy are an effective method to promote the development of enterprise remanufacturing.At the same time,consumer behavior has an impact on the market demand for new product and remanufactured product,reshaping the closed-loop supply chain equilibrium.Taking ZL cement enterprise as an example,this paper considers government subsidy and introduces consumer behavior into the closed-loop supply chain network,which theoretically expands the closed-loop supply chain network equilibrium model considering consumer behavior and provide reference for government departments formulating subsidy policy and enterprise optimize production decisions in practice.The main research work of this paper is:(1)Considering consumers’ low-carbon preference and using the variational inequality method to establish closed-loop supply chain network equilibrium model with profit and carbon emissions objectives under government subsidy,and find that government subsidy in appropriate interval and consumers’ low-carbon preferences can help increase sales of remanufactured products and improve environmental performance.In this paper,consumers’ low carbon preference is introduced into the closed-loop supply chain network to study closed-loop supply chain equilibrium decisions with economic and environmental objectives.Most of the existing literature only considers the price difference between new products and remanufactured products.According to the survey of ZL cement enterprises,the models and algorithms in the paper are verified.Results show that the government appropriately controls the subsidy within the range of(0,20)yuan/ton can lower the carbon emissions while increasing the market share of remanufactured products and the remanufacturing enthusiasm of enterprise.Consumers’ low-carbon preference can help remanufactured products cannibalizate new products and reduce the carbon emssions of closed-loop supply chain network,but also lead to lower profit of the closed-loop supply chain.(2)Considering consumers’ perceived value and using the variational inequality method to construct closed-loop supply chain network equilibrium model under the government subsidy aiming at profit maximization and carbon emissions minimum,and finding that government subsidy can help increase the market share of remanufactured products within a certain range and decrease carbon emission while the loss of corporate profits are small.The dimensions of consumers’ perceived value have different effects on the economic goals and carbon emission targets of closed-loop supply chain network.In this paper,consumers’ perceived value is made up of consumers’ perceived service life and perceived low carbon levels and the market demand is extended to an uncertain situation,and the closed-loop supply chain network equilibrium decision in this context is studied.Existing research ignores the heterogeneity of new and remanufactured products in terms of consumers’ perceived service-life and perceived low-carbon level.According to the data of ZL cement enterprise,the model and algorithm in the paper are verified.Results show that government subsidy can significantly increase the market share of remanufactured products and improve environmental performance while ensuring higher economic benefits within the range of(0,5)yuan/ton.In addition,a higher consumers’ perceived price,perceived service life and perceived low carbon level can increase sales of remanufactured products.The higher of the first two can help improve the environmental performance of closed-loop supply chain network,but lead to lower economic performance,while the higher of the last is harmful to the environment,but can contribute to improving economic benefits.更多还原
