【摘要】：自1983年第一例轉(zhuǎn)基因煙草的誕生,到1994年美國孟山都公司的延熟西紅柿的批準(zhǔn)上市,轉(zhuǎn)基因技術(shù)得到了迅猛地發(fā)展。但發(fā)展的同時也伴隨著諸多爭議,爭議的焦點主要集中在:(1)轉(zhuǎn)基因食品是否真正安全;(2)轉(zhuǎn)基因食品是否應(yīng)該進(jìn)行商業(yè)化推廣;(3)轉(zhuǎn)基因食品是否應(yīng)該進(jìn)行標(biāo)識。各方學(xué)者專家觀點不一,并且始終沒有一個準(zhǔn)確的定論。隨著食品安全問題的日益突出,轉(zhuǎn)基因食品成為消費者關(guān)注的焦點。無論是轉(zhuǎn)基因技術(shù)本身還是未來的應(yīng)用與發(fā)展,消費者在其中都扮演著十分重要的角色。本研究通過問卷調(diào)查的方式了解南昌市消費者對于轉(zhuǎn)基因食品認(rèn)知程度及購買意愿情況。根據(jù)問卷體系運(yùn)用SPSS軟件分別分析了影響消費者對轉(zhuǎn)基因食品了解程度、獲取信息渠道、優(yōu)缺點感知、購買行為與意愿、對轉(zhuǎn)基因食品整體評價和信任程度的因素。并運(yùn)用Mplus軟件進(jìn)行結(jié)構(gòu)方程模型的構(gòu)建,探究購買意愿與認(rèn)知、感知收益、感知風(fēng)險和信任度4個潛在變量之間的關(guān)系,并得出感知風(fēng)險與感知收益是影響消費者購買意愿最重要的因素。通過對研究結(jié)果的分析得出以下主要結(jié)論:(1)消費者對轉(zhuǎn)基因食品認(rèn)知水平有限,個體差異較為明顯;(2)感知收益與感知風(fēng)險是影響消費者購買意愿的重要因素;(3)消費者對信息來源主體不信任,且存在信息不對稱;(4)消費者對轉(zhuǎn)基因食品發(fā)展前景較為看好,但需加強(qiáng)監(jiān)管。并針對以上結(jié)論提出了對應(yīng)的建議:(1)加強(qiáng)宣傳科普力度,提高消費者認(rèn)知;(2)加強(qiáng)安全評價,適時適度推廣;(3)規(guī)范信息傳播渠道,解決信息不對稱;(4)加強(qiáng)政策引導(dǎo),完善相關(guān)法律法規(guī);(5)加大投資力度,培養(yǎng)民族企業(yè)。關(guān)于轉(zhuǎn)基因食品的研究多為基于轉(zhuǎn)基因技術(shù)本身、道德倫理和經(jīng)濟(jì)政治意義進(jìn)行探討,本研究以消費者為視角,了解其真實感受與需求。可以為政府制定相關(guān)管理政策、生產(chǎn)經(jīng)營者進(jìn)行商業(yè)推廣提供科學(xué)依據(jù),有利于生物科技產(chǎn)業(yè)的健康發(fā)展。
[Abstract]:From the birth of the first transgenic tobacco in 1983 to the approval and listing of the long-ripened tomatoes of Monsanto Corporation in 1994, the transgenic technology has been developed rapidly. But at the same time, the development is accompanied by many controversies, which focus on: (1) whether GM food is really safe, (2) whether GM food should be commercialized and popularized; (3) whether GM food should be marked. Scholars and experts from all sides have different views and have never had an accurate conclusion. With the growing problem of food safety, genetically modified food has become the focus of attention of consumers. Consumers play a very important role in the application and development of GM technology itself and in the future. The purpose of this study was to investigate the cognition and purchase intention of GM food in Nanchang City. According to the questionnaire system, SPSS software was used to analyze the factors influencing consumers' understanding of GMF, access to information, perception of advantages and disadvantages, purchase behavior and willingness, overall evaluation and trust of GMF. Using Mplus software to construct the structural equation model, to explore the relationship between purchase intention and four potential variables: cognition, perceived income, perceived risk and trust. It is concluded that perceived risk and perceived income are the most important factors affecting consumers' purchase intention. The main conclusions are as follows: (1) the cognitive level of GMF is limited, and the individual differences are obvious; (2) perceived income and perceived risk are the important factors that affect consumers' willingness to buy. (3) consumers do not trust the source of information, and there is information asymmetry. (4) consumers have a good prospect for the development of GM food, but need to strengthen supervision. In view of the above conclusions, the corresponding suggestions are put forward: (1) to strengthen the propaganda of science popularization, to improve consumers' cognition; (2) to strengthen the safety evaluation, to promote it in a timely and appropriate manner; (3) to standardize the channels of information dissemination, and to solve the information asymmetry; (4) strengthen policy guidance, perfect relevant laws and regulations, (5) increase investment, train national enterprises. The research on genetically modified food is mostly based on the transgenic technology itself, moral ethics and economic and political significance. This study takes the consumer as the perspective to understand its true feelings and needs. It can provide scientific basis for the government to formulate relevant management policies and for production operators to carry out commercial promotion, which is conducive to the healthy development of biotechnology industry.
