We examine the value of blockchain for disclosing secondhand product quality in a supply chain in which contributors consign secondhand products to an online platform that resells them and competes with suppliers of new products. We find that the platform is more likely to provide a uniform (differential) pricing strategy with new products when the revenue sharing portion of the consignment contract is sufficiently low (high). Moreover, surprisingly, without blockchain, the platform prefers moderately perceived and true quality secondhand products, instead of extremely high or low quality. With blockchain, the platform prefers selling low-uniqueness and low-quality (or high-uniqueness and high-quality) secondhand products. Furthermore, we find that with blockchain, horizontal integration is more effective in improving the supply chain’s total profit. A win-win-win outcome can be achieved for the platform, the supplier, and consumers in a supply chain that sells low-uniqueness products.

我们检查了区块链在供应链中公开二手产品质量的价值，在该供应链中，贡献者将二手产品委托给一个在线平台，该平台转售这些二手产品并与新产品的供应商竞争。我们发现，当寄售合同的收益分成部分足够低（高）时，该平台更有可能为新产品提供统一（差异）定价策略。而且，令人惊讶的是，没有区块链，该平台更喜欢中等感知和真实质量的二手产品，而不是极高或极低的质量。借助区块链，该平台更喜欢销售低独特性和低质量（或高独特性和高质量）的二手产品。此外，我们发现使用区块链，横向整合对于提高供应链的总利润更为有效。在出售低独特性产品的供应链中，平台，供应商和消费者可以实现双赢。
