项目摘要

In this study, we has been engaged in the following three analysis, to reveal effects of policy mix between infrastructure Improvement and other regional policies.(1) Evaluation of National Land Development Observed from Internal Migration in the Postwar Japan.The regional population is one of the most important factor for national land development. Total migrants reached peak in the later half of 1970s, with rapidly increasing inflow in the three large metropolitan areas, and we have an overpopulated/depopulated area problem. This analysis aims to analyze the mechanism population changes effected with national policies by using the AGE Model with endogenous population changes. In order to conform to AGE Model, the another construct a Residential Choice Model and evaluate the national policies in the view of regional population changes in the postwar Japan.(2) Evaluation of Interregional High Speed Transport Networks for Decenralization of Business HeadquatersSince the overconcentratio … More n in Tokyo Metropolitan Area has caused various economic social problems in Japan it is often said that political and business headquaters functions should be decentralized. Current high speed transport networks, however, might not be able to supply enough service for the decentralization policies. This research aims to evaluate high-speed transport networks for alternative policies by means of interregional travel demand models.(3) An Estimation of Energy Consumption due to Interregional Commodity Flows in Japan.In the recent trend of energy consumption by sector, on one hand the energy consumed by industrial sector is diminishing gradually, on the other the energy consumed by transport sector is increasing. Therefor to control transport energy consumption is important for global and local environmental problems. In this analysis as the basic study for the problem, an energy quantity consumed by interregional commodity flows in Japan is estimated. Firstly interregional commodity flows are estimated by the commodity flow census. Secondly the flows are changed to energy consumption quantity by an energy consumed by transporting a unit commodity flow. Finally in the case study, the energy diminishing quantity due to the modal shift from track/car to ship/train is estimated. Less

在本研究中，我们进行了以下三个分析，以揭示基础设施改善与其他区域政策之间的政策组合的影响。（1）从战后日本内部人口迁移观察的国家土地开发评价。区域人口是国家土地开发最重要的因素之一。 20世纪70年代后半叶，移民总量达到顶峰，三大都市区的流入量迅速增加，出现人口过多/人口稀少的问题。本分析旨在利用内生人口变化的AGE模型来分析国家政策影响人口变化的机制。为了符合AGE模型，构建居住选择模型，并从战后日本区域人口变化的角度评估国家政策。(2)企业总部去中心化的区域间高速交通网络评估由于东京都市区的过度集中，在日本造成了各种经济社会问题，人们常说政治和企业总部职能应该分散。然而，当前的高速交通网络可能无法为权力下放政策提供足够的服务。本研究旨在通过区域间出行需求模型来评估高速交通网络的替代政策。(3)日本区域间商品流动引起的能源消耗估算。从近期分部门能源消耗趋势来看，一方面工业部门的能源消耗逐渐减少，另一方面交通部门的能源消耗却在增加。因此，控制交通能源消耗对于解决全球和地方环境问题具有重要意义。在作为该问题的基础研究的本分析中，对日本国内的地区间商品流通所消耗的能源量进行了推算。首先通过商品流量普查估算区域间商品流量。其次，将单位商品流量所消耗的能量转化为能量消耗量。最后，在案例研究中，估计了由于从轨道/汽车到船舶/火车的模式转变而导致的能量减少量。较少的
