On the contrary, it was shown that the scale of arriving region’s industrial agglomeration have affected on the volume of domestic physical distribution of light manufacturing. Moreover, it was shown that transportation cost or transit time have much explanation power as a variable of transportation resistance than the haul distance that included the influence of geographical feature (it is called real extension of a road). ii) And, using survey dataconducted to the ICT related firms located in industry clusters in Japan and Korea, we revealed technological networks connecting to the oversea regions and based on geographical proximity contributed firm’s continuity.
