Abstract: In order to ensure the quality and safety of agricultural products, China has made many achievements in traceability of agricultural products. But some key problems are still existing, such as information asymmetry, difficulty of traceability, inefficient supervision from government, low social participation, etc.. This paper analyzed the reason for less development of China's agricultural products multisided platform (MSP) from MSP theory; put forward the suggestion of constructing multisided platform for quality and safety of agricultural products traceability based on Time-Space Traceability Code(TSTC) of national unity, combing the advantages both of MSP and traceability of agricultural products. This paper also conducted overall design for this platform, including how many sides involved in this design, total architecture design and basic function design,etc.. Finally, the paper designed the management process for traceability of agricultural products, so as to achieve effective traceability for agricultural products.

Key words: quality and safety of agricultural products, traceability, multisided platform(MSP), platform construction

摘要： 为了保障农产品质量安全，我国在农产品溯源方面取得了很多有益成果。但是依然存在企业间信息不对称、溯源困难、政府无法有效监管、社会参与度低等关键问题。从多边平台的理论研究出发，分析了我国农产品多边平台发展缓慢的原因；结合多边平台和农产品溯源的各自优势，提出了构建全国统一的基于时空追溯码的农产品质量安全溯源多边平台，并对该多边平台进行了总体设计，包括平台的参与方设计、平台的整体架构设计和平台基本功能设计；最后研究设计了多边平台下的农产品溯源管理流程，以期实现农产品高效追溯。
