In this paper, as a part of understanding the stock effect of road development, we examine the long-term stock effect of the development of highway network over the past half century since the first opening of the roads, using a Spatial Computable General Equilibrium (SCGE) model. As a result of the gradual development of the network, the value added change which is industrial stock effect index mainly occurs at the Honshu area from the Kanto and Koshinetsu regions to the Chugoku region, confirming the contribution of industrial activities in these regions to the growth of the Japanese economy. On the other hand, regional benefit on the household are widely spread to the entire country, confirming the contribution of highway network to the balanced development of the nation.
