【摘要】：作為一種新興高科技產品,轉基因食品(Genetically Modified Food,GMF)的研究與發(fā)展已經成為了現代轉基因技術研究與應用的最重要成果之一,給人類帶來了巨大的包括經濟、生態(tài)和社會等方面的效益。但同時,轉基因食品由于其安全性問題也備受關注和爭議。感知價值作為影響消費者購買行為的重要因素之一,消費者對轉基因食品的感知價值在一定程度上影響著政府對轉基因食品的相關決策,進而決定轉基因食品的產業(yè)化和商業(yè)化進程。因此,本文在文獻研究的基礎之上,構建了消費者轉基因食品感知價值影響因素的研究模型。首先,利用武漢市432名轉基因食品消費者的調查數據,對消費者轉基因食品感知價值情況有了初步的了解;其次,采用了探索性因子分析對消費者轉基因食品感知價值維度進行了劃分;最后,運用相關分析和回歸分析探究了消費者產品知識、安全風險感知以及卷入程度對其轉基因食品感知價值的影響。最終得到如下結論:(1)消費者對轉基因食品價值的感知整體不高,均值為2.8912,介于不太同意和比較同意之間。雖然消費者對轉基因食品價值的感知整體不高,但也并不如想象中的低,經過適當的引導,有較大提升的空間。(2)消費者轉基因食品感知價值包含社會價值、安全價值、成本優(yōu)勢和功能價值4個維度。其中,社會價值包含抗蟲、抗逆、抗病毒、減少農藥使用以及提高產量3個指標,安全價值包含營養(yǎng)好、口感好、利于健康三個方面,成本優(yōu)勢主要包括價格低和購買便利兩個方面,功能價值則包含美觀和耐貯藏兩方面。(3)不同個體特征的消費者對轉基因食品價值感知存在差異。不同性別、職業(yè)、年齡和文化程度的消費者對轉基因食品各維度的感知價值有所不同。(4)產品知識、安全風險感知與卷入程度均顯著影響消費者轉基因食品感知價值。其中,消費者的產品知識和卷入程度正向影響其轉基因食品感知價值,而安全風險感知則與其感知價值呈現負相關關系�；谏鲜鲅芯拷Y論,本文主要從增加消費者產品知識、降低安全風險感知和提高卷入程度3個方面提出了相應的政策與建議,為企業(yè)和政府有針對性的制定提高消費者轉基因食品感知價值的政策提供了理論支撐,最終可以促進轉基因產業(yè)的健康、可持續(xù)發(fā)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.
