在本文中，我们研究了消费者的良好农业规范（GAP）的价值，使用支付卡条件估值法（CVM）和条件排名法（CRM）。在日本宫城县仙台市进行问卷调查。从200名参与者的答复进行了分析，以衡量的边际支付意愿（MWTP）的情况下，生产的西红柿在宫城县的GAP。从CVM和CRM估计的MWTP分别为12.5日元和9.9日元。在熊本生产的番茄的情况下，根据CRM估算的GAP的MWTP为9.5日元，这几乎等于在宫城生产的番茄的情况下的GAP的MWTP。根据这个结果，我们可以得出结论，无论产地如何，GAP的MWTP都在10日元左右。此外，本研究亦以181位受访者为样本，探讨受访者的特质对GAP评价的影响。在宫城和熊本的情况下，受访者的性别和年龄影响了他们对GAP的评价。倾向于购买宫城农产品的受访者对宫城GAP的评价有所上升，而几乎每天都购买西红柿的受访者对熊本GAP的评价则有所下降。
In this paper, we examined consumers' valuation of good agricultural practice (GAP), using a payment card contingent valuation method (CVM) and a contingent ranking method (CRM). A questionnaire survey was conducted in Sendai city, Miyagi prefecture, Japan. Responses from 200 participants were analyzed to measure the marginal willingness to pay (MWTP) for GAP in the case of tomatoes produced in Miyagi prefecture. The MWTP estimated from the CVM and CRM was 12.5 yen and 9.9 yen a piece, respectively. The MWTP for GAP estimated from the CRM in the case of tomatoes produced in Kumamoto was 9.5 yen, which was almost equal to the MWTP for GAP in the case of the tomatoes produced in Miyagi. This result leads us to the conclusion that regardless of place of origin, the MWTP for GAP seems to be approximately 10 yen a piece. The CRM was also used to explore the effects of respondents' characteristics on their valuation of GAP, based on 181 respondents. The respondents' sex and age influenced their valuation of GAP in the case of both Miyagi and Kumamoto. While the respondents who had a tendency to purchase agricultural products produced in Miyagi increased their valuation of GAP for Miyagi, those who purchased tomatoes almost every day decreased their valuation of GAP for Kumamoto.
