【摘要】：民以食为天,食以安为先。食品安全问题一直备受人们和媒体及监管部门的瞩目。这些食品安全问题不仅给消费者带来健康威胁,同时也给涉事企业带来严重的惩戒。食品安全问题频繁出现,食品安全事件为全社会所瞩目,媒体起着非常重要的桥梁作用。新闻媒体对食品安全事件的报道,既缩短了公众获取信息时间,也履行了媒体的社会责任和舆论监督作用。凭借身对公众舆论和行为的影响力,媒体对食品安全事件的报道,客观上使涉事企业受到更多的公众关注,降低了消费者的信息不对称,使食品安全事件对企业的负面影响无限放大,涉事企业会受到更严重的市场惩戒。因此,本文开头提出了两个问题:市场能否对发生食品安全问题的企业施加惩戒;媒体关注是否会加深市场惩戒效应。本文第一章主要是对食品安全、媒体关注和市场惩戒进行了概念界定。第二章针对三者之间的相关文献进行了梳理,现有文献以媒体关注角度的文献居多,而站在食品安全与媒体关注的实证研究较少。本文在第三章进行了食品安全和媒体关注的制度背景介绍。主要介绍了食品安全监管部门的制度和职能变迁、传媒行业的体制变革。第四章针对本文的研究方向,对食品安全、媒体关注与市场惩戒之间的关系进行了理论分析并提出假设。以食品安全和市场惩戒负向作用,媒体关注作为调节变量加重食品安全和市场惩戒的负向作用为研究假设,在第五章和第六章对其关系进行了模型构建和实证检验。本文以2006-2015年在中国质检网、国家食品药品监督管理局和国家质量监督检验检疫总局官方网站上公布的有食品安全问题的上市公司作为研究样本,发生食品安全事件的上市公司和媒体关注变量的数据通过手工搜集整理,按照研究假设建立研究模型并运用SPSS统计软件进行验证,论证过程采用描述性统计、相关性分析、回归分析及稳健性检验得出了与假设一致的结论。在第七章对研究结论进行了总结,提出了本文的不足和对未来研究的展望。最后,根据食品安全、媒体关注与市场惩戒的论证结果表明:食品安全与当期企业绩效和市场反应呈负相关,即发生食品安全事件的上市公司会使当年企业绩效降低,出现负的市场反应。在媒体关注的调节作用下市场惩戒会加重,即媒体关注会使食品安全与企业业绩、食品安全与市场反应的负向作用更加显著。根据本文论证结论提出相应的政策建议,对我国现存食品安全问题的解决具有一定现实意义。
[Abstract]:The people take food as the day, and food takes peace as the first.Food safety issues have been the focus of attention of people and the media and regulatory authorities.These food safety problems not only pose health threats to consumers, but also bring serious punishment to businesses involved.Food safety issues appear frequently, food safety events are attracting the attention of the whole society, and the media play a very important role in bridging.The news media report on food safety not only shortens the time for the public to obtain information, but also fulfils the social responsibility of the media and the supervision of public opinion.By virtue of their influence on public opinion and behavior, and the media coverage of food safety incidents, objectively, the enterprises involved in the matter have received more public attention, and the information asymmetry of consumers has been reduced.The negative effects of food safety incidents on enterprises will be magnified, and the enterprises involved will be more severely punished by the market.Therefore, at the beginning of this paper, two questions are raised: whether the market can punish companies with food safety problems and whether media attention will deepen the market disciplinary effect.The first chapter defines the concept of food safety, media concern and market discipline.The second chapter combs the related literature between the three. Most of the existing literature is from the perspective of media concern, but the empirical research on food safety and media concern is less.The third chapter introduces the system background of food safety and media concern.This paper mainly introduces the system and function change of food safety supervision department and the system change of media industry.In the fourth chapter, the relationship among food safety, media concern and market discipline is analyzed and hypothesized.Based on the negative effect of food safety and market discipline and the negative effect of media attention as a regulating variable to aggravate food safety and market discipline, the relationship between food safety and market discipline is constructed and tested empirically in chapters 5 and 6.This paper uses listed companies with food safety problems published on the website of the China quality Inspection Network, the State Food and Drug Administration and the State Administration of quality Supervision, Inspection and Quarantine from 2006 to 2015 as research samples.The data of listed companies and media concerned variables of food safety incidents are collected and sorted by hand, and the research model is established according to the research hypothesis and verified by SPSS statistical software. The demonstration process adopts descriptive statistics and correlation analysis.The results of regression analysis and robustness test are consistent with the hypothesis.In the seventh chapter, the conclusion is summarized, the deficiency of this paper and the prospect of future research are put forward.Finally, according to the results of food safety, media concern and market discipline, the results show that food safety is negatively correlated with current enterprise performance and market reaction, that is, the listed company with food safety events will make the enterprise performance decrease in that year.There was a negative market reaction.Under the regulation of media attention, market discipline will be aggravated, that is, media attention will make food safety and enterprise performance, food safety and market reaction more negative effect.According to the conclusion of this paper, it is of practical significance to put forward corresponding policy suggestions to solve the existing food safety problems in China.
