在食品可追溯体系推广与普及的过程中,满足消费者对可追溯标签上所呈现信息的内容与类型的期望至关重要.通过相关信息的公开,能够有助于消费者辨别食品的质量与安全,并提高消费者的信任.为了解消费者对可追溯标签上信息内容的偏好与需求,本文选择猪肉为例,从目前我国已经实施的猪肉可追溯体系,提取18种涵盖养殖、屠宰与销售的可追溯信息.通过解释结构模型（ISM）和五位专家的反复调查构建了将不同可追溯信息分别与食品安全、食品质量和食品信任三种标准相对应的网络框架,基于该框架并运用网络层次分析法（ANP）构建评估模型,展开150位消费者的随机调查,研究消费者对猪肉可追溯信息的偏好.评估结果显示,消费者偏好的8种猪肉信息依次为：兽药与使用情况、饲料与添加剂、饲养过程、养殖环境、疫苗、包装日期、质量认证与标志、检疫信息.本文的研究结论表明,在当前的背景下,政府引导推广和普及猪肉可追溯体系的过程中,应重点支持包含生猪养殖环节中养殖环境、疫苗、兽药、饲料与添加剂、疾病、检疫等信息,加工环节的分割包装日期信息,以及质量认证与标志信息等可追溯猪肉的生产,并引导消费者的消费.本文的主要研究结论和政策建议同时可能对类似于黄浦江死猪事件,尤其是遏制事件发生后可能产生的重大疫情传播与扩散具有重要的现实意义,有助于政府及时、有效地防控社会层面上的死猪恐慌.

英文摘要：

It is important to meet consumers＇ demand for information concerning different aspects in building traceable food information system which can help consumers distinguish quality and safety of food and enhance consumers＇ confidence by publicizing relevant information. To understand consumers＇ preferences and needs for the information about the content labels, in this study, we take pork as an example, involving information from 18 aspects covering the breeding, slaughter and sale from the current pork tracing information system in China. Through interpretative structural modeling method （ISM） and repeated investigation with five experts, we build a network framework, in which different traceable information meeting three standards, namely food safety, food quality and trust. Based on the framework and the analytic network process （ANP） an evaluation model has been constructed for investigation in 150 consumers to study consumers＇ preference for traceable pork information. The results show that animal drugs, feed additives, feeding process, culture environment, vaccine, date of packaging, quality certification and logo, and quarantine information are the attributes of traceable information that consumers are more concerned about when purchasing pork products. The conclusion shows that, at present, in the promotion and popularization of pork traceable information system, the government should support mainly on the information about culture environment, veterinary medicine, vaccine, feed and additives, disease, and quarantine in pig breeding, date of packaging in processing, and quality certification and details of logo in production of traceable pork, and should guide the consumption trend of consumers. The main research conclusions and suggestions may be of important practical significance for the Huangpu River pig events, especially for controlling the epidemic spread and diffusion after events of food safety, and help government promptly and effectively prevent events caused by dead pig and contro
