【摘要】 为探究中国猪肉质量安全的关键环节,本文利用web数据挖掘技术和内容分析方法,提取出中国2009—2014年发生的1 624个猪肉质量安全事件,通过横向的判别与定位矩阵、纵向的年际演化趋势来反映猪肉安全的薄弱环节。研究表明:(1)加工环节是猪肉质量安全问题的高危环节,爆发事件频次最多且比例随时间而增加;(2)加工环节的原材料使用不当及流通环节的销售不合格肉制品是猪肉安全问题的主因;(3)小商贩、小作坊和小企业是加工环节的主要责任主体,各种销售商是流通环节的主要责任主体。基于上述结论,本文提出如下对策:(1)合理配置监管资源,强化对关键环节、高危风险因子的监控;(2)扩大监管范围,创新监管手段,加强对小规模生产主体的监管;(3)鼓励社会第三方力量的参与和监督;(4)加强宣传与教育,提高生产经营者的法律意识和业务素质。更多还原

【Abstract】 To explore the critical control points of pork’s quality and safety in China, web data mining technology and content analysis are used to extract the 1624 Quality Safety incidents associated with pork from 2009 to 2014. By cross-analysis in discrimination and positioning matrix and time-series-analysis in trends, we conclude the key weaknesses in pork supply chain. The results reveal that:(1) manufacture processing is the uppermost step of quality and safety problems, which has the maximum frequency of events and the increasing proportion with time;(2) improper use of raw materials in manufacture processing step and unqualified selling of pork in distribution chain are the main cause of quality and safety issues;(3) small-scale of vendors, workshops and businesses are the primary subjects of liabilities. At last, four countermeasures and suggestions are proposed:(1) the allocation of regulatory resources should be more rationally to strengthen the supervision of high- risk chains;(2) intensify the supervision of small-scale production subjects by means of expanded regulation scope and innovative supervision mode;(3) encourage third forces’ participation and supervision of pork’s quality and safety;(4) promote the legal awareness and professional competence of production operators through publicity and education.更多还原
