2011年3月11日，东日本大地震给日本东北部地区造成严重破坏。此次灾难导致福岛第一核电站发生严重核事故，导致日本北部和东部地区出现辐射泄漏。自事故发生以来，消费者对食品放射性污染的担忧与日俱增。日本政府已发布了有关从市场上撤回食品的某些法律准则。然而，由于污染问题，福岛县及周边地区对农产品的需求下降。在本文中，该研究利用2011年3月至2012年2月对居住在东京和大阪都市区的已婚女性进行的网络调查收集的数据，估算了福岛县和茨城县菠菜的消费者WTA。在估算中，本研究将WTA分为两部分：1）健康风险评估，基于放射性污染的健康风险评估产品；2）原产地评估，基于无污染产品的原产地。主要结果如下：（1）东京和大阪都市区消费者评价存在差异。两个地区的健康风险评估相似；然而，不同地区的原产地评价不同。 (2)污染程度-WTA曲线应呈凹形，污染程度变化的影响逐渐减弱。结果表明，消费者因担心污染而回避农产品的现象依然强烈且粘性较大。
On March 11, 2011, the Great Eastern Japan Earthquake wreaked havoc across northeastern Japan. The disaster caused a serious nuclear accident at the Fukushima I Nuclear Power Plant, which led to radiation leakage across northern and eastern Japan. Concerns over the radioactive contamination of food have grown among consumers since the accident. The Japanese government has issued certain legal guidelines for withdrawing food from markets. However, the demand for agricultural products from Fukushima Prefecture and neighboring areas decreased because of contamination concerns. In this paper, the research estimated consumer WTA of spinach from Fukushima and Ibaraki prefectures using the data collected by internet surveys conducted from March 2011 to February 2012 of married women living in the Tokyo and Osaka metropolitan areas. In the estimate this research divided the WTA into two parts: 1) health risk evaluation, the evaluation of products based on health risk from radioactive contamination, and 2) origin evaluation, based on the origin of products without contamination. The main results are as follows: (1) Consumer evaluations were different between the Tokyo and Osaka metropolitan areas. The health risk evaluation was similar in both areas; however, the origin evaluation was different between the areas. (2) Level of contamination-WTA curves should be concave and the effect of the change of level of contamination diminishes gradually. The results indicate that consumers' evasion toward agricultural food with fear of contamination is still strong and sticky.
