我国城市居民对转基因食品的购买行为研究.docVIP

为什么部分消费者转向购买非转基因食用油？ ——以江苏省城市居民为例 陈希 (南京农业大学经济管理学院) 摘要：我国超市转基因食用油的市场份额在强制食品标签政策实施后统计上显著下降，但仍然保持着相当高的市场份额，并在长期中伴随着不显著的微弱增加趋势。本文在以上实际销售数据得到的市场份额趋势基础上，根据城市居民入户调查数据，实证检验超市消费者的各类特征对其食用油购买行为的影响，并分析差异化的消费者购买行为如何加总形成转基因油的市场趋势。我们得出以下两点主要结论：（1）消费者的购买行为受到购买决策者的特征、风险意识、家庭社会经济因素等各类特征的影响；（2）转基因油市场份额的改变受到较高收入者的“结构效应”影响，而低收入者的“总量效应”没有明显发生，一系列因素可能导致对转基因油市场份额的低估。 关键词： 城市居民 转基因食用油 市场份额 购买行为 Why a Part of Consumers Change Their Purchasing Pattern to Non-Biotech Oils? A Study of Urban Residents in Jiangsu Chen Xi (College of Economics and Management, Nanjing Agricultural University) Abstract: The market share of biotech edible oils in Chinese supermarkets showed a statistically significant decrease after the enforcement of mandatory food labeling policy. In the long run, biotech oil would keep on a dominative market share, though small and statistically insignificant in its growing trend. Based on the above results using supermarket actual sales data, this paper uses micro survey data collected from urban residents to test the influences of consumers’ characteristics on their purchasing decisions. Then, we will analyze how changes of biotech oil market share are formed by distinct consumers’ behaviors. It is found that consumers’ purchasing decisions are influenced by buyers’ characteristics, risk consciousness, socioeconomic factors of families and so on. Besides, the changes of biotech oil market share are affected by the structural effect of the rich, while there is no apparent gross consumption effect of the poor, which could be underestimated by a series of factors. Key Words: urban residents biotech edible oil market share purchasing behavior 引言 近年来,我国转基因农作物种植面积飞速增长,并成为世界重要的转基因产品进口国(James，2005)。2003年8月我国颁布转基因有关管理条例之后，在中央和地方政府的严格监督下，转基因强制标签政策在食用油行业得到比较好的实施。我国的转基因强制标签政策可能对转基因大豆、油菜籽等产品的消费和贸易产生很大的影响。但影响程度的大小主要取决于我国消费者对转基因食用油的接受程度，以及转基因标签对消费者态度和行为的影响大小，这些有待于深入的研究。消费者角度的深入研究可以为转基因食品的商业化提供关键的帮助。消费者的信息对于我国政府引导转基因技术的发展，管理和规范转基因食品市场具有重要的参考价值。
