This paper aims to analyze the interregional industrial linkage on social overhead capital investment between the broad economic network in Korea. In order to analyze the interregional industrial linkage we need to measure forward linkage effect and backward linkage effect by using interregional input-output table. In this process, linkage effect can be measured by demand-driven input-out model which uses Leontief Inverse Matrix Coefficient and supply-driven input-output model which uses Goshian Inverse Matrix Coefficient. This paper compared the results produced by the two models above, based on interregional input-output table released by The Bank of Korea 2007. The two models presented similar linkage effect. The detailed analysis is as follow. First of all, it was proven that backward linkage effect had huge intra-regional linkage effect and modest inter-regional linkage effect. The more vulnerable the broad economic networks had, the more modest another interregional industrial backward linkage effect they witnessed. On the contrary, forward linkage effect showed huge intra-regional linkage effect and modest inter-regional linkage effect. The more vulnerable the broad economic network had, the more huge another interregional industrial backward linkage effect they witnessed. Specially, the capital area enjoyed huge forward linkage effect from the broad economic networks.
