An input-output table captures the relation among industries. Traditionally, it is calculated in a static way. However, the interaction among industries persists over time and hence belongs to a dynamic reciprocal relation. Accordingly, this paper utilizes the dynamic spillover index innovated by Diebold and Yilmaz (2009) to calculate an input-output table .The sample is quarterly gross domestic product from 1981 to 2011 of 19 industry1 digit. This study applies a first order vector autoregressive to estimate the interaction of 19 industries and calculate spillover index from 1 step ahead forecasting to 5 steps ahead forecasting. The result shows that the spillover index across all industries is increased over time, which reveals a considerable dynamic interaction among industries.
