| 中文摘要 |
| 为了研究区块链技术如何影响生鲜供应链成员、社会福利以及在资金约束情形下, 生鲜供应链何时应该采用区块链技术, 本文针对由生鲜电商平台、资金约束的供应商组成的生鲜供应链, 构建博弈模型系统分析区块链带来的效应对各方均衡策略及福利的影响, 探讨了在无融资、银行融资以及混合融资情形下区块链的市场效应和成本效应对资金约束生鲜供应链和社会福利的影响并分析了区块链技术采纳的条件. 结果表明: (1) 当供应商存在资金约束且无法获取融资时, 平台不应该采纳区块链技术; (2) 在中等市场效应下区块链采纳虽利于供应商, 却损害平台利润; (3) 供应商融资成本越高, 平台在区块链采纳后通过压低批发价攫取利润的动机越强; (4) 在区块链技术的降本效应和市场扩展效应较低, 而新鲜度信任在中等水平时, 区块链采纳提升消费者剩余, 但可能降低社会总福利. |
| 英文摘要 |
| To study how blockchain technology affects the members of the fresh produce supply chain and social welfare, as well as when the fresh produce supply chain should adopt blockchain technology under capital constraints, this paper targets a fresh produce supply chain composed of a fresh produce e-commerce platform and a capital-constrained supplier, constructs a game-theoretic model to systematically analyze the impacts of blockchain-enabled effects on the equilibrium strategies and welfare of each stakeholder, explores the influences of the market effect and cost effect of blockchain on the capital-constrained fresh produce supply chain and social welfare under non-financing, bank financing and hybrid financing scenarios, and identifies the adoption conditions of blockchain technology. The results show that: (1) When the supplier has capital constraints and cannot obtain financing, the platform should not adopt blockchain technology. (2) Under a medium market effect, although the adoption of blockchain benefits the supplier, it damages the platform's profit. (3) The higher the supplier's financing cost, the stronger the platform's motivation to extract profits by lowering the wholesale price after adopting blockchain. (4) When the cost - reduction effect and market expansion effect of blockchain technology are low, and the freshness trust is at a medium level, the adoption of blockchain increases consumer surplus. However, it may reduce the total social welfare. |
