The objective of this study is to identify the underlying subgroups of Chinese consumers in terms of their perceptions and attitudes toward GM foods. In particular, we address the following specific questions: may researchers segment Chinese urban consumers in terms of their attitudes and perceptions toward GM foods? Are there any relationships between segmented consumer groups and other factors – such as their exposure to GM knowledge and socio-demographics? And, what policy implications can be drawn from this research to the future biotech development in China? Based on a large-scale survey data collected by the authors in 2002 and 2003 in 11 cities of China, this research applies consumer research methodologies. The combination of factor and cluster analysis enables us to identify successfully and consistently four Chinese consumer clusters based on their perceptions and attitudes toward GM foods, which include a food safety cluster, a nutritional technologist cluster, a GM skeptic cluster, and a cluster of GM for non-food promoter. 相似文献

We analyzed the determinants of acceptance of genetically modified food (GMF) by using the probit model. In this study, we found that around 41% of the students are willing to buy GMF, and acceptance of GMF is less in female respondents than male respondents. The findings indicate that in India, benefit perception of GMF outweighed the risk perception. We also found that respondents’ trust in international organizations for truthful information has a positive and significant influence on acceptance of GMF. 相似文献

Genetically modified rice with a high folate content, i.e., folate biofortified rice, was recently developed to tackle folate deficiency. A consumer segmentation study is conducted to explore its market potential in the Chinese Shanxi Province, where the burden of folate deficiency is among the world’s highest. Cluster analysis of 451 rice consumers identified three segments: enthusiasts (14.2%), cautious (41.2%), and opponents (44.6%). Enthusiasts obtain the highest score of GM food knowledge and attitudes and have the highest GM rice acceptance rate, followed by cautious and reluctant consumers. Regarding GM food information, enthusiasts use almost entirely audiovisual channels and rely more on the industry, while other segments depend more on informal channels and anti-GM sources. Trust levels in these channels/sources differ between enthusiasts (high), opponents (neutral), and cautious (low). Based on multinomial regression, a targeted communication approach is recommended with a focus on female, cautious consumers and rural, low-educated opponents. 相似文献

Abstract To communicate effectively with consumers about genetically modified (GM) food, gaining insight in the formation of consumer attitude regarding GM food is essential. Therefore, the current paper first reviews relevant literature describing how consumer attitudes towards GM food are formed. Next, Structural Equation Modelling (SEM) is applied to own quantitative data to model the formation of consumer attitude towards GM food. Previous analysis of these quantitative data led to the identification and characterisation of four consumer segments (Halfhearted, Green Opponents, Balancers and Enthusiasts) based on beliefs and attitudes towards GM food. Based on the SEM results, recommendations are formulated for each of the four identified consumer segments. 相似文献

采用对二次干涉自相关(IAC)迹线求一阶导数,得到干涉自相关导数光谱(D-MOSAIC),并利用该导数光谱对啁啾有很高灵敏度的特性,对高斯型强度分布的线性啁啾、平方啁啾脉冲进行数值计算与模拟,得到导数光谱的峰值与啁啾大小的对应关系.提出了一种新颖的测量超短激光脉冲啁啾的方法,同时得出干涉自相关导数光谱能够精确地测量超短激光脉冲的啁啾大小. 相似文献

财务报告舞弊行政处罚与可感知审计质量 总被引:1,自引:0,他引:1

以2001年至2008年间非金融类、非外资类正常交易A股公司为研究样本,考察财务报告舞弊行政处罚是否传递了可感知审计质量信息,实证研究结果表明:投资者总体上并不认可财务报告舞弊行政处罚传递了可感知审计质量信息,仅当投资者观察到反映坏消息的审计意见(如审计师出具非标审计意见、审计意见未改善等)和反映审计师声誉信息(如审计师受到行政处罚)的情况下,投资者才认为财务报告舞弊行政处罚传递了可感知审计质量信息。 相似文献

随着我国经济的发展,汽车工业得到迅速的发展,但是我们也面临着一个严峻的问题,那就是汽车的废旧轮胎的处理问题。我国每年产生的废弃轮胎大约有1400kt。废旧轮胎对环境有着严重的污染作用。因为这种材料不容易分解,需要相当长的时间。植物的生长会因之破坏,随之滋生的蚊虫也会影响人类的健康。因此,如何处理废旧轮胎成了亟待解决的问题。现在有一种工艺,可以变废为宝。那就是将废旧轮胎磨成橡胶粉,将其用于道路改性沥青当中。经实验证明,这种沥青能够改善沥青的高温与低温性能,大大降低路面的损害,同时能在很大程度上改善废旧轮胎产生的污染问题。目前,我国针对这方面的研究还不够成熟,相关的标准也不完善。 相似文献
