政府补贴和企业履责下平台供应链定价与减排研究

摘要/Abstract

摘要： 针对单个制造商单个平台组成的供应链,假定制造商实施减排策略、平台履行企业社会责任(corporate social responsibility, CSR),政府分别基于制造商减排研发成本和基于低碳产量进行补贴,平台供应链分别采取批发模式和代理模式,构建4种组合情形下制造商与平台之间的Stackelberg博弈模型,求解供应链最优定价和减排决策;基于对比分析研究政府最优补贴策略和平台供应链最优销售模式;通过数值仿真分析两种补贴方式下补贴系数、消费者低碳偏好、平台履行CSR以及低碳推广努力对供应链决策和社会福利等的影响。研究表明:碳减排水平、制造商及供应链总利润、环境改善程度和社会福利水平在代理模式下均高于批发模式;在批发模式下,低碳产品零售价格及平台利润更高。基于产量的补贴策略有利于提高制造商利润,而基于成本的补贴策略对平台利润更有利;从提高碳减排水平、环境改善程度和社会福利水平维度看,政府采用基于减排研发成本的补贴策略最优,但在产量补贴方式模式下社会福利水平提升更显著。

Abstract: Considering the supply chain composed of a single manufacturer and a single platform, where the manufacturer implements the emission reduction strategies and the platform fulfills CSR(corporate social responsibility), the Stackelberg game models between manufacturer and platform are built under four combination cases that the government subsidizes the manufacturer based on the R&D cost for emission reduction and based on the low-carbon production, and the platform supply chain adopts the wholesale mode and the agency mode, respectively, together with the optimal pricing and emission reduction decisions of the supply chain by solving the models. Based on comparative analysis, the optimal subsidy strategy of the government and the optimal sales model of the platform supply chain are obtained. Through numerical simulation, we analyze the impacts of the subsidy coefficient, consumers low-carbon preference, platforms fulfillment of CSR, and low-carbon promotional efforts on the supply chains decision-making and social welfare under the two subsidy modes. The research shows that: the level of carbon emission reduction, the total profit of manufacturers and supply chain, the degree of environmental improvement and the level of social welfare are higher in the agency mode than in the wholesale mode. In the wholesale model, the retail price of low-carbon products and platform profits are higher. The subsidy strategy based on the low-carbon production is more conductive to increasing manufacturers profits, while the strategy based on emission reduction cost is more favorable to platforms profits. From the dimensions of improving the level of carbon emission reduction, the degree of environmental improvement and the level of social welfare, the subsidy strategy based on the R&D cost is optimal strategy of government, and the improvement of the level of social welfare is more significant under the subsidy strategy based on the low-carbon production.

Key words: government subsidies, carbon emission reduction, platform sales mode, stackelberg model, corporate social responsibility
