生态标识对粮食价格的影响及增值贡献分析——以大米、挂面的特征价格调查为例

抽取武汉市6家大型连锁超市内117个大米和132个挂面为样本,采用基于主成分分析的特征价格模型测算绿色标识、有机标识、无公害标识、地理标识等指标对于粮食价格的影响及其增值贡献程度。研究表明:绿色标识、有机标识、无公害标识、地理标识会对大米价格产生正向影响;绿色标识、质量标识会对挂面价格产生正向影响。得出结论:对生态标识类粮食产品的研究,既推动了粮食产品的定价,又加强了消费者对生态标识型粮食产品的认知,同时还提高了农民种植生态粮食的积极性,有效改善了农田生态环境。

Impact of Eco-labeling on Grain Price and Its Value-added Contribution --Taking Hedonic Price of Rice and Noodle for Example

Based on 117 valid samples of rice and 132 valid samples of noodles from 7 supermarkets in Wuhan, this paper uses Hedonic price model based on Principal Component Analysis to assess the effect of green label, pollution-free label, organic certification and geographical indications on grain price and value-added degree. The result shows that green label, pollution-free label, organic certification and geographical indications have positive effect on the price of rice while green label and quality label have positive effect on noodles. In conclusion, the research on eco-labeling grain not only promotes pricing of food products but also enhances consumer＇s cognition of ecological awareness of food products. Meanwhile, it improves the farmers＇ enthusiasm to plant ecological grain so as to improve ecological environment of farmland.
