(1)Questionnaire surveyWe conducted questionnaire survey about rice farmers with cooperation of person in charge of the ministry of agriculture, forestry and fishery and local governments to get reaction data on a paddy-field rental transaction. In addition, the data on farmland and irrigation facilities were obtained by this survey. In questionnaire survey, anonymity was considered for protection of personal information.(2)Estimation of rental transaction modelReaction functions of farmers, who want to rent paddy-fields to others and to be rented from others, were formulated based on a stochastic choice model, and those functions were estimated by questionnaire data. Furthermore, the model which decides a rent and rental agreement level at the supply and demand balance point was built, and used for simulation analysis.(3)Elucidation of an influence factorThis study specified influence factors on rental rates and rental agreement level by simulations, such as consolidation of paddy-fields by the public projects, renting evasion, changes in social and economic variable of rice price and wages, and geographical condition of paddy fields.(4)ApplicabilityApplicability of this model was examined by comparing data in real rental transactions with a result of simulation. In addition, an effect of paddy-fields consolidation projects was evaluated quantitatively by this simulation, and an economic loss in a Japanese rental market was quantified.(5)Publication of resultResults of this analysis were discussed in the international conferences, and published as articles in academic journals.

（1）问卷调查为了获得稻田租赁交易的反应数据，我们与农林水产省负责人和地方政府合作，对稻田农户进行了问卷调查。此外，本次调查还获得了农田和灌溉设施的数据。在问卷调查中，匿名被认为是保护个人信息。（2）租金交易模型的估计基于随机选择模型，建立了农户对租田意愿和被租意愿的反应函数，并利用问卷调查数据对这些反应函数进行了估计。在此基础上，建立了在供需平衡点上确定租金和租赁协议水平的模型，并进行了仿真分析。（3）影响因素的解析本研究通过模拟，明确了公共项目对稻田的集中、逃租、米价和工资等社会经济变量的变化、稻田的地理条件等对租金率和租赁协议水平的影响因素。（4）模型的适用性通过比较真实的租赁交易数据和模拟结果，检验了模型的适用性。此外，稻田整理项目的效果进行了定量评估，通过这种模拟，并在日本租赁市场的经济损失进行了量化。（5）结果的发表本分析的结果在国际会议上进行了讨论，并作为论文在学术期刊上发表。
