食品可追溯体系是指对涵盖食品产业链中各个环节的过程进行跟踪和追溯的能力，对食品安全起着重要作用。尽管目前中国已经颁布了各种法规来加强食品安全，但实施过程中的一些差距可能会降低法律的有效性。基于这一情况，采用了混合数据收集方法，旨在实现两个目标：探讨中国食品追溯系统应用的条件；并为香港的一家中型餐馆构建了食品追溯系统。具体为：用包含结构化问卷的定量方法分析了影响食品追溯系统的因素；同时采用案例研究方法对建立的食品追溯系统进行了全面SWOT分析。结果表明，消费者的心理特征、社会人口学特征和消费者对食品安全的认知影响着食品追溯系统。SWOT框架显示，尽管拟议的可追溯系统存在一些弱点，但各组织可以利用该系统的优势和现有的机会来操作该工具。结果表明，该系统操作简单，成本低；适用于类似案例这样规模的食品机构及产业应用食品可追溯。

Food traceability system refers to the ability to track and trace the process covering all links in the food industry chain, which plays an important role in food safety. Although China has promulgated various regulations to strengthen food safety, some gaps in the implementation process may reduce the effectiveness of the law. Based on the current situation a mixed method of data collection was adopted to achieve two objectives: to explore factors affecting the adoption of food traceability systems in China and to construct a food traceability system for a medium-sized restaurant in Hong Kong. In particular, a quantitative method involving a structured questionnaire analyzed the factors affecting food traceability systems, while a case study approach was applied to conduct a thorough SWOT analysis of the proposed food traceability system. The results indicate that consumers’ psychographic characteristics, socio-demographic profiles, and consumer cognition of food safety affect food traceability systems. The SWOT framework revealed that, despite the internal weaknesses and external threats to the proposed system, organizations can take advantage of the strengths and existing opportunities of the system to operate the tool. Literature reference, questionnaire survey and field investigation are used as methods respectively in project, then a traceability system for Wing's Catering was designed and this system was analyzed by SWOT analysis. As a result, the system is simple to operate within low cost, and it is suitable for similar specification like Wing's to apply food traceability.
