SCGE model building for logistics network and policy impact analysis

本研究旨在建立物流网络的空间可计算一般均衡（SCGE）模型，并分析效率提升和政策变化对运输部门的影响。具体而言，我们构建了北海道与日本其他地区之间的两个区域间CGE模型。该模型的特点是对运输方式和分布水平有估计的弹性/参数，可以应用于SCGE模型。通过模拟分析，通过合作运输系统的演进，评估了合作运输模式对区域经济的溢出效应和运输份额的变化。

The purpose of this study is to build the spatial computable general equilibrium (SCGE) model for logistics network, and to analyze the impact of efficiency improvements and policy changes on transportation sector. Specifically, we constructed two inter-regional CGE model between Hokkaido and other Japanese regions. The characteristic of this model is to have estimated elasticity/parameter for transportation modes and distribution levels for applying to the SCGE model. As simulation analysis, we evaluated the spillover effects to regional economy and the changes of transportation share by mode through the progress of cooperative transportation system.
