考虑需求扰动及企业社会责任行为的绿色供应链决策

Green supply chain decisions with consideration of demand disruption and corporate social responsibility

为了探讨需求扰动及零售商企业社会责任(CSR)行为对绿色供应链决策的影响,构建了制造商主导的绿色供应链模型,并得到需求扰动前后的均衡结果,然后研究了绿色供应链的协调问题,最后将模型拓展到绿色供应链与传统供应链横向竞争的情形。结果表明,当需求发生大幅扰动时,制造商需要调整产品绿色度,此时零售商的CSR行为会增大制造商对产品绿色度的调整量;需求扰动会使绿色供应链系统利润偏离预期,此时零售商的CSR行为会加剧需求扰动对绿色供应链系统利润的影响,不利于绿色供应链的稳定运营;二部定价—成本契约可以实现绿色供应链协调;绿色供应链与传统供应链的横向竞争会增强零售商CSR行为对产品绿色度最优调整量和绿色供应链系统利润偏离程度的影响。

To explore the influences of demand disruption and corporate social responsibility on green supply chain decisions,the equilibrium solutions under the manufacturer-led green supply chain model was examined,and the coordination issue in the green supply chain was investigated.The model was expanded to the supply chain competition situation.The results showed that the manufacturer needed to adjust the“greenness”of the product following the large demand disruption,and the retailer’s CSR behavior would increase the amount of adjustment of the“greenness”of the product by the manufacturer at this time.Demand disruption would deviate the actual profit of green supply chain system away from the expected value,in which case,the retailer’s CSR behavior would enhance the influence of demand disruption on the profits of the green supply chain system.Moreover,a two-part tariff and cost sharing contract was proposed to coordinate the supply chain.Supply chain competition would enhance the influence of retailer’s CSR behaviors on the extent of optimal“greenness”adjustment to the products,as well as the profit deviation levels of the green supply chain system.
