项目摘要

Urban transportation system is usually developed with some peripheral infrastructures and shopping complex. These exert the effect and uneffect on the periphery area individually. Although some of existing methods are able to measure the total of the benefit, they are not able to evaluate the rate of contribution that each part of the comprehensive development makes. By applying the Hedonic approach to the subway system in Sendai the present paper separates the contribution of such effect by part of the development. The existence of joint development effect with related infrastructure is confirmed by adopting the explanation variable with the form of the product in a land price equation. Furthermore, it is also confirmed that evaluating the convenience of plural shopping centers as the log sum variable increases the coefficient of determination. Several preconditions are required in order that the measuring value by this approach is a real value. Especially the same utility functions of residents of these preconditions are focused. By developing the model that hypothesized 2 kind of residents whose preference for using subway systems differ, the nature of the evaluated effect on the base of the latter price system is examined theoretically. In the case that the person who prefers for subway is inclined to inhibit the subway station periphery, it is proven that this approach evaluates an effect smaller than real value. Furthermore, by this approach , the effect showed that is measured smaller than about 13% of real value. Also, expanding the research object in the road and flood control institution between the cities, a joint development effect is calculated by using a general equilibrium model. Although only about 0.3% of a joint development effect is calculated in this case, the existence is confirmed.

城市交通系统通常会配套一些周边基础设施和购物中心。这些分别对周边区域产生影响和不影响。现有的一些方法虽然能够测算总体效益，但无法评价综合发展各部分的贡献率。通过将享乐方法应用于仙台地铁系统，本文将这种效应的贡献按部分开发分开。采用地价方程中乘积形式的解释变量来证实与相关基础设施存在联合开发效应。此外，还确认了将多个购物中心的便利性评价为对数和变量会增加确定系数。为了使这种方法的测量值是真实值，需要几个前提条件。尤其是这些前提条件下的居民的相同效用函数受到关注。通过建立假设两类对使用地铁系统偏好不同的居民的模型，从理论上检验了基于后者价格体系的评估效果的性质。在偏好地铁的人倾向于抑制地铁站周边的情况下，证明该方法评估的效果小于真实值。此外，通过这种方法，测量的效果显示小于实际值的约 13%。同时，将研究对象扩大到城市之间的道路和防洪机构，利用一般均衡模型计算共同发展效应。虽然在这种情况下仅计算出约0.3%的联合开发效果，但已证实其存在。
