进行特征定价分析是为了确定商品市场价值中各种属性的隐含价值。在这项研究中，享乐定价分析，以衡量粮食质量的搜索和经验属性的贡献，在菲律宾的两个农村城镇的大米价格。从受访者的大米样品进行定量的粮食质量常规评估。特别是，糊化温度和垩白，这两个参数，通常是通过视觉评分评估，通过纯粹的定量手段（差示扫描量热法和数字图像分析）进行了评估。结果表明，被调查者食用的大米主要具有相似的物理和化学品质属性。受访者透露的偏好是菲律宾大米消费者以前报道的典型偏好。特征回归分析表明，粮食质量特征，影响价格的收入阶层不同。影响价格的一些性状或社会经济因素包括破碎率、胶稠度和家庭人均大米消费量。稻米价格存在收入效应，影响价格的特征因收入阶层而异。
Hedonic pricing analysis is conducted to determine the implicit values of various attributes in the market value of a good. In this study, hedonic pricing analysis was applied to measure the contribution of grain quality search and experience attributes to the price of rice in two rural towns in the Philippines. Rice samples from respondents underwent quantitative routine assessments of grain quality. In particular, gelatinization temperature and chalkiness, two parameters that are normally assessed through visual scores, were evaluated by purely quantitative means (differential scanning calorimetry and by digital image analysis). Results indicate that rice consumed by respondents had mainly similar physical and chemical grain quality attributes. The respondents’ revealed preferences were typical of what has been previously reported for Filipino rice consumers. Hedonic regression analyses showed that grain quality characteristics that affected price varied by income class. Some of the traits or socioeconomic factors that affected price were percent broken grains, gel consistency, and household per capita rice consumption. There is an income effect on rice price and the characteristics that affect price vary between income classes.
