我国消费者对有机食品的态度研究——以南京市调研结果为例 总被引:1,自引:0,他引:1
本文通过问卷调查方式分析了有机产品在中国南京主流超市的市场情况和人们对有机食品的认知情况。调查发现:当今人们对有机食品的关注程度还有待于提高。部分消费者虽然对有机食品有积极的认知,但只有1.25%的人曾经购买过有机产品。原因可能除了价格因素以外,还与人们的受教育程度,职业差别和有机理念的深浅以及购买渠道的便易与否皆有重要关系。此外,还与有机市场具有市场份额小,品种相对单一,价格偏高有一定的关系。建议扩大宣传、提高营销手段以提高人们对有机产品的认知;同时,加强有机生产和加工的监督和管理,严格控制产品质量,以加强人们对有机产品的信心。 相似文献

A focus group study using four groups of food shoppers provides insights into consumers’ knowledge, beliefs, and behaviors regarding organic foods. Two focus groups consisted of shoppers who regularly bought organic foods and two focus groups of shoppers who predominantly purchased conventional foods. Participants in one of the conventional groups were all Caucasian; in the other they were all African-American. While familiarity with organic foods was much lower in the African-American group, its members were more receptive and positive towards organic foods. Likewise, the African-American shoppers were more accepting of price premiums for organics foods. In comparing the two organic shopper groups with the two conventional shopper groups, it was found that the former were generally more knowledgeable about organic foods. They were also more likely to follow a special diet than conventional Caucasian shoppers. However, the behavior of organic shoppers varied widely. The research supports examining social justice and access as motivations for changing policies to support organic agriculture.

Organic food standardization is an increasingly important strategy for dealing with consumer concerns about the environment, animal welfare, health, and the economic structure of food production. But the ways in which this consumer-oriented strategy is introduced, organized, and debated vary considerably across countries. In Sweden, a nongovernmental organization [KRAV (Association for Control of Organic Production)] – consisting of social movement organizations, associations for conventional and organic farmers, and the food industry – has been quite successful in promoting organic food labeling as an eco-label. KRAV has developed a complementary position vis-à-vis the state and EU regulatory framework. In the US, the federal government controls standardization. The government frames the label as a “marketing label,” thus rejecting the idea that organic food production would have any significant advantages for the environment or, indirectly, for human health. This framing is separate from the ones created by organic constituencies, leading to deeper controversies than in Sweden. The purpose of this paper is to examine why standardization has followed different patterns in the two settings. We analyze context factors (i.e., political culture, pre-regulatory arrangements, and organizational structures) and process factors (i.e., framing and organizing). What are the benefits of a state-centric versus a nonstate-driven approach regarding powerful standardization? The paper shows that both settings provide not only “threats of regulatory occupation” from actors not committed to organic principles but also avenues for substantial standardization in the future, albeit through different channels. 相似文献
