基于区块链的策略型消费者购买行为及供应链协调

Research on Strategic Consumers’Purchasing Behavior and Supply Chain Coordination Based on Blockchain

基于供应链的视角研究区块链对消费者策略性购买行为、供应链成员定价决策和最优利润的影响。研究表明,采用区块链进行一体化决策时,供应链系统更倾向于在第一期设立高价以获得最优利润;供应商在第二期采用区块链时,供应链系统的总销售数量大于没有采用区块链时的总销售数量,且零售商在分散化决策下第一期价格低于一体化决策下第一期价格,导致更多的策略型消费者选择提前购买;在两种决策模式下,无论消费者策略性程度如何,如果供应商在第二期采用区块链,那么消费者的策略性等待购买阈值大于没有采用区块链时的策略性等待购买阈值,而且策略型消费者会加大在两期中的购买总数量;在满足一定条件下,采用区块链的供应链系统可以通过收益共享契约实现供应链完美协调。

Based on the perspective of supply chain,this paper studies the impacts of blockchain on the consumers’strategic purchase behavior,the supply chain members’pricing decisions and optimal profits.The research shows that the supply chain system is more inclined to set a high price in the first period to obtain the optimal profit when blockchain is adopted for the integrated decision-making;When the supplier adopts blockchain in the second period,the total sales volume of the supply chain system is greater than that when blockchain is not adopted,and the retailer’s price in the first period under the decentralized decision is lower than the price in the first period under the integrated decision,which results in more strategic consumers choosing to purchase in advance;Under the two decision-making models,regardless of the consumers’strategic level,if the supplier adopts blockchain in the second period,the strategic waiting purchase threshold of the consumers is greater than that when blockchain is not adopted,and the strategic consumers will increase the total purchase quantity in the two periods.Under certain conditions,the supply chain system adopting blockchain can realize perfect coordination of supply chain through revenue sharing contract.
