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.

城市交通系统通常以一定的周边基础设施和购物中心为主。这些因素分别对外围区产生影响和不产生影响。现有的一些方法虽然能够衡量效益的总和，但却不能评价综合发展各部分的贡献率。通过将Hedonic方法应用于仙台市地铁系统，本文将这种效应的贡献按开发的部分分开。采用地价方程中产品形式的解释变量，证实了与相关基础设施共同开发效应的存在。此外，还证实了以对数和变量评价多个购物中心的便利性会增加决定系数。为了使这种方法的测量值是一个实值，需要几个先决条件。特别关注了这些前提条件下居民的相同效用函数。通过建立假设两类居民使用地铁系统的偏好不同的模型，从理论上考察了基于后一种价格体系的评价效果的性质。在地铁偏好者倾向于抑制地铁站外围的情况下，证明了该方法的评价效果小于实际值。此外，通过这种方法，效果显示测量小于实际值的13%左右。同时，将研究对象扩大到城市间的道路和防洪机构，利用一般均衡模型计算了城市间的共同发展效应。虽然在这种情况下只计算了约0.3%的联合发展效应，但证实了其存在。
