政治信息接触与价值观如何影响中国网民的转基因食品态度?基于“格-群”文化理论的实证探索

How do Political Information Exposure and Values Affect Chinese Netizens’ Attitude toward Genetically Modified Food? An Empirical Exploration Based on the Grid–Group Cultural Theory

公众转基因食品态度的形成及媒介信息对其的影响长期受到社会关注。除了媒介信息的建构之外,转基因食品态度同样也是一个内在的文化问题,需将人们在感知技术风险时的文化价值偏向考虑在内。本文结合“格-群”文化理论,基于2017年网民社会意识调查(N=2,376),探讨了时政新闻接触和政治价值观对我国网民转基因食品态度的影响。结果显示,时政新闻接触能够显著地负向预测网民对转基因食品的态度;政治价值观(如文化态度、民族中心主义、主观意识形态自评)既能直接作用于网民的转基因食品态度,也能在时政新闻接触对转基因食品态度的影响之间起中介作用。研究证实了政治信息接触和文化认知世界观对网民转基因食品风险感知形成的重要解释作用。

The public attitude toward genetically modified(GMO) food and the influence of media on it has been investigated as an important issue. However, not only media construction, but also internal culture is closely related with the public attitude toward GMO food. Based on the grid–group cultural theory, with the data from the 2017 survey of the Chinese netizens(N = 2,376), this empirical study explores the influence of political news exposure and political values on Chinese netizens’ attitude toward GMO food. The results suggested that political news exposure could negatively predict the netizens’ attitudes toward GMO food. Political values(such as cultural attitudes, ethnocentrism, self–evaluated subjective ideology) can not only directly influence the netizens’ attitude toward GMO food, but also acting as moderators between political news exposure and netizens’ attitude toward GMO food. In other words, both political information exposure and cultural worldview could work as important explanation mechanisms that affect netizens’ perception of the risk relating with GMO food.
