摘要
为提高平台供应链系统利润,在考虑平台网络外部性影响下,根据平台是否采纳区块链技术,分别构建了在分散决策和集中决策下的4种模型,并对模型均衡结果进行对比分析。研究发现:无论平台是否采纳区块链技术,随着网络外部性增大,产品价格和平台供应链中各成员利润均增加;消费者对验真时间和伪劣品的敏感系数增大时,产品价格和平台供应链中各成员的利润均减少;当平台采纳区块链技术时,消费者信任度增加,产品价格和平台供应链中各成员的利润均增大;在分散决策下,当平台采纳区块链技术的投入成本小于某一阈值时,平台供应链系统利润高于不采纳区块链技术利润。
In order to improve the profits of the platform supply chain system,four models under decentralized decision-making and centralized decision-making are constructed according to whether the platform adopts blockchain technology,considering the influence of platform network externalities,and the equilibrium results of the models are compared and analyzed.The results show that whether the platform adopts blockchain technology or not,with the increase of network externality,the price of products and the profits of all members in the platform supply chain will increase.When the sensitivity coefficient of consumers to truth-checking time and shoddy products increases,the price and the profit of each member in the platform supply chain decrease.When the platform adopts blockchain technology,the consumer trust increases,and the price and profits of all members in the platform supply chain increase.Under decentralized decision-making,when the input cost of the platform adopting blockchain technology is less than a certain threshold value,the profit of the platform supply chain system is higher than that without adopting blockchain technology.
