区块链技术背景下跨国供应链决策与协调研究

Research on Decision and Coordination of Transnational Supply Chain Under the Background of Blockchain Technology

根据区块链技术在需求预测以及溯源防伪等方面的应用背景,本文以跨国制造商和零售商组成的二级供应链为研究对象,研究加征关税背景下区块链技术对不同契约下跨国供应链决策的影响机理。研究表明,成本共担契约和批发价格契约下,单位关税增加额增加会导致制造商降低产品质量,使批发价格和销售价格降低,进而损害消费者利益;产品质量、销售价格等与制造商的风险规避系数负相关;在收益共享契约下,批发价格、销售价格随单位关税增加额、制造商风险规避系数的增加而增加,产品质量随单位关税增加额、制造商风险规避系数的增加而降低。

According to block chain technology in the aspects of demand forecasting and tracing anti-counterfeiting applica⁃tion background,based on the two-level supply chain composed of multinational manufacturers and retailers as the research object,research the impact of blockchain technology on transnational supply chains under different contracts under the background of tariff increase.The research shows that under cost-sharing contract and wholesale price contract,the increase of unit tariff will lead the manufacturer to reduce the product quality,so that the wholesale price and sales price will decrease,and then harm the interests of consumers.Product quality and selling price are negatively correlated with the risk aversion coefficient of manufacturers.Under the revenue-sharing contract,the wholesale price and sales price are positively correlated with the increase of unit tariff and the manufacturer's risk aversion coefficient,while the product quality is negatively correlated with the increase of unit tariff and the manufacturer's risk aversion coefficient.
