采纳区块链技术的两级供应链信息共享博弈OA北大核心CSTPCD

To address the question of whether small and medium-sized supply chain members establish an informa-tion sharing platform based on blockchain technology and the value of the establishment,information sharing based on blockchain technology in a supply chain dominated by a retailer and containing two manufacturers with unequal status is analysed by considering the quality and price sensitivity of consumers.The article constructs a traditional cooperation model,a short-term model of information sharing based on blockchain technology,and a long-term model,respectively,to explore the value of the supply chain and model selection under different models.The results show that in the short term,the establishment of an information sharing platform based on blockchain technology will widen the status gap between manufacturers,resulting in the strong getting stronger and the weak getting weaker,and the profit of retailers will be dam-aged.In the long run,the quality endeavour effect of information sharing will narrow the gap between manufacturers and increase profits,and retailers and the entire supply chain will experience significant profit increases after short-term pain.It can be seen that when consumers are more sensitive to price and quality,the establishment of an information sharing platform based on blockchain technology is advantageous to stronger manufacturers,disadvantageous to weaker manufac-turers,and beneficial to the supply chain in the long run;otherwise,the absence of an information sharing platform based on blockchain technology is advantageous to the supply chain and weaker manufacturers.
