基于区块链技术的农产品质量信息披露策略分析

An Analysis of Quality Information Disclosure Strategy of Agricultural Product Based on Blockchain Technology

农产品质量信息的虚假披露导致价格机制失灵,制约着农产品市场的发展.区块链中信息透明可追溯的特性,为解决农产品供应链质量信息虚假披露提供了新的解决方案.然而高昂的区块链采用成本,市场消费者类型,区块链信息追溯精度都影响着区块链的采用.文章运用信号博弈,以价格为信号探究了农产品供应链中区块链采用策略和质量信息披露策略.研究发现:1)农超只有在溯源信息增益较高时才会采用区块链技术;且农户的种植成本较低时,农超采用区块链技术意愿更强烈.2)在不采用区块链技术且种植成本较低时,低质量农户有动机虚报高价混淆市场.3)农超采用区块链技术可能会损害农户的收益,随着信息敏感的消费者数量增加,农产品供应链中各方都能从中获益.

The price mechanism failure caused by fake quality information disclosure restricts the development of the agricultural product market.The transparent and traceable feature of information in the blockchain provides a new solution to the problem of fake quality information disclosure in the agricultural product supply chain.However,the high cost of blockchain,consumer preferences in the market,and block traceability accuracy all affect the strategy of adopting blockchain.This paper uses the signaling game and sets price as the signal to explore blockchain adoption strategies and quality information disclosure strategies in the agricultural product supply chain.This paper finds that:1)The agricultural supermarket will adopt blockchain technology only when the information increase is high;when farmers'planting cost is low,the agricultural supermarket will be more willing to adopt blockchain.2)When blockchain technology is not adopted and the planting cost is low,low-quality farmers have the incentive to deliberately set high prices to confuse the market.3)The adoption of blockchain technology by the agricultural supermarket may harm farmers'profits.Only when the consumers'preference is more information-sensitive,all participants in the agricultural product supply chain can benefit from blockchain.
