基于结构方程模型的食品安全满意度影响因素分析

On Factors Influencing Food Safety Satisfaction Based on Structual Equation Model

文章应用结构方程方法研究大学生对食品安全总体评价满意度的影响因素。研究方法为收集某高校2018年12月至2019年1月间699份有效调查问卷。首先使用结构方程模型分析数据,然后将699份有效问卷根据媒体种类进行分类,分为传统媒体样本和互联网样本,并对二者进行对照分析。研究结论:对全样本而言,对食品安全总体评价的影响因素,直接影响的因素依次为社会管理评价、食品现状评价,这两个变量对食品安全评价为正向影响,而残留物质评价对食品安全评价则为负向影响,即对食品有害残留物质越关注,则对食品安全的满意度越低。间接影响因素为公众关注评价,其对食品安全满意度的相关性为正,且显著相关,表示公众对食品安全信息越关注,其对食品安全满意度越高。根据食品安全来源进行数据分类,经过对照分析互联网样本和传统媒体样本分群组分析,研究发现大学生对传统媒体的信任度大于网络媒体,而对于有害残留物质对满意度的影响程度,互联网用户更为敏感,并显著相关。研究成果可以为食品监管部门提高管理绩效提供实证参考资料。

With the assistance of structual equation, the paper attempted to reveal the factors influencing college students’ food safety satisfaction through 699 questionnaires collected within the period from December,2018. to January 2019. Following the data analysis conducted with structual equation model and the classfication of those questionnaires into conventional media samples and Internet ones, further comparisons were made with corresponding conclusions subsequently showing the direct infuencing factors and indiect ones in relation to the food safety satisfaction. The conclusions made are expected to illuminate the management of food regulaors and sectors.
