【摘要】：作为一种新兴高科技产品,转基因食品(Genetically Modified Food,GMF)的研究与发展已经成为了现代转基因技术研究与应用的最重要成果之一,给人类带来了巨大的包括经济、生态和社会等方面的效益。但同时,转基因食品由于其安全性问题也备受关注和争议。感知价值作为影响消费者购买行为的重要因素之一,消费者对转基因食品的感知价值在一定程度上影响着政府对转基因食品的相关决策,进而决定转基因食品的产业化和商业化进程。因此,本文在文献研究的基础之上,构建了消费者转基因食品感知价值影响因素的研究模型。首先,利用武汉市432名转基因食品消费者的调查数据,对消费者转基因食品感知价值情况有了初步的了解;其次,采用了探索性因子分析对消费者转基因食品感知价值维度进行了划分;最后,运用相关分析和回归分析探究了消费者产品知识、安全风险感知以及卷入程度对其转基因食品感知价值的影响。最终得到如下结论:(1)消费者对转基因食品价值的感知整体不高,均值为2.8912,介于不太同意和比较同意之间。虽然消费者对转基因食品价值的感知整体不高,但也并不如想象中的低,经过适当的引导,有较大提升的空间。(2)消费者转基因食品感知价值包含社会价值、安全价值、成本优势和功能价值4个维度。其中,社会价值包含抗虫、抗逆、抗病毒、减少农药使用以及提高产量3个指标,安全价值包含营养好、口感好、利于健康三个方面,成本优势主要包括价格低和购买便利两个方面,功能价值则包含美观和耐贮藏两方面。(3)不同个体特征的消费者对转基因食品价值感知存在差异。不同性别、职业、年龄和文化程度的消费者对转基因食品各维度的感知价值有所不同。(4)产品知识、安全风险感知与卷入程度均显著影响消费者转基因食品感知价值。其中,消费者的产品知识和卷入程度正向影响其转基因食品感知价值,而安全风险感知则与其感知价值呈现负相关关系。基于上述研究结论,本文主要从增加消费者产品知识、降低安全风险感知和提高卷入程度3个方面提出了相应的政策与建议,为企业和政府有针对性的制定提高消费者转基因食品感知价值的政策提供了理论支撑,最终可以促进转基因产业的健康、可持续发展。
[Abstract]:As a new high-tech product, the research and development of genetically modified Modified (GMF) has become one of the most important achievements in the research and application of modern transgenic technology. Ecological and social benefits But at the same time, genetically modified food because of its safety issues are also concerned and controversial. Perceived value is one of the important factors that affect the consumer's purchasing behavior. To a certain extent, the perceived value of the consumer to genetically modified food affects the government's decision on GM food. And then determine the industrialization and commercialization process of GM food. Therefore, on the basis of literature research, this paper constructs a research model of the influencing factors of consumer GM food perceived value. First of all, using the survey data of 432 genetically modified food consumers in Wuhan City, we have a preliminary understanding of the perceived value of genetically modified food consumers. The dimension of perceived value of GMF is divided by exploratory factor analysis. Finally, the knowledge of consumer products is explored by correlation analysis and regression analysis. The effect of safety risk perception and involvement degree on the perceived value of GM food. Finally, the following conclusion is drawn: 1) consumers' perception of the value of GM food is not high as a whole, the average value is 2.8912, which is between different and relatively agreed. Although consumers' perception of the value of GMF is not high, it is not as low as imagined. After proper guidance, there is great room for improvement.) the perceived value of GMF by consumers includes social value and safety value. Cost advantage and function value are four dimensions. Among them, social value includes three indexes: anti-insect, anti-retrograde, anti-virus, reducing pesticide use and increasing yield. The safety value includes three aspects: good nutrition, good taste and good health. Cost advantage mainly includes two aspects: low price and convenience of purchase, while functional value includes aesthetic and storage-resistant aspects. (3) consumers with different individual characteristics have different perception of value of GM food. Consumers with different gender, occupation, age and education level had different perceived value of GMF in each dimension. (4) Product knowledge, safety risk perception and involvement degree all significantly affected the perceived value of GMF. The perceived value of GMF is positively affected by the product knowledge and involvement of consumers, while the perceived value of GMF is negatively correlated with safety risk perception. Based on the above conclusions, this paper puts forward corresponding policies and suggestions from three aspects: increasing consumer product knowledge, reducing safety risk perception and increasing involvement degree. It provides theoretical support for enterprises and governments to formulate policies to improve the perceived value of GM food for consumers, which can ultimately promote the healthy and sustainable development of the GM industry.
