项目摘要

(1)Using the metropolitan database that we have developed, we obtained quantitative estimates of agglomeration economies, and, based on the estimates, we tested empirically if Tokyo is too big.(2)We have completed building the spatial database of the official land prices of the Tokyo metropolitan area, and have conducted a spatio-temporal analysis of the land market. We also developed a functional coefficient regression model that use non-parametric type estimation methods and applied it to the analysis of the official land price data. We conducted statistical testing of issues such as how big are the effects on land price of proximity to commercial facilities (such as shopping centers) and to green zones (such as parks and forests) and whether or not these effects are different between the suburbs and city centers(3)We developed a new ridge type estimator for a regression model and examined the properties of the estimator. Using tile new type estimator, we constructed a quality-adjusted price index for second-hand condominium housing.(4)Using the spatial database, we applied Markov Chain Monte Carlo method to obtain Bayes estimates of spatial factors affecting the effects of marketing activities and consumers' spatial purchasing behavior.(5) We established a new cost-benefit analysis methodology for investments in social overhead capital that has network effects. Based on these works, an error in the cost-benefit manual for transportation investment used in Japan was pointed out(6) We analyzed a variety of the economic effects of agglomeration economies in the monopolistic competition framework in economic geography and international economics

（1）利用开发的都市圈数据库，对集聚经济进行了定量化的估计，并在此基础上对东京是否过大进行了实证检验。(2)We完成了东京都市圈官方地价空间数据库的建立，并对土地市场进行了时空分析。我们还建立了一个使用非参数型估计方法的函数系数回归模型，并将其应用于官方地价数据的分析。我们对商业设施（如购物中心）和绿色地带（如公园和森林）的距离对地价的影响有多大以及这些影响在郊区和市中心之间是否不同等问题进行了统计测试。（3）我们开发了回归模型的新岭型估计量，并检查了估计量的性质。利用新的估计量，我们建构了一个二手公寓住宅品质调整价格指数。（4）利用空间数据库，应用马尔可夫链蒙特卡罗方法，得到影响营销活动效果和消费者空间购买行为的空间因素的Bayes估计。(5)我们建立了一个新的成本效益分析方法，投资在社会间接资本，具有网络效应。在此基础上，指出了日本交通投资成本效益手册中的一个错误。（6）在经济地理学和国际经济学的垄断竞争框架下，分析了集聚经济的各种经济效应
