摘要


產業關聯表大多以靜態方式描述投入產出關係,其模型一般以靜態方式呈現,然而,產業之間是隨著時間存在動態關聯。本文根據Diebold and Yilmaz (2009) 方法估計台灣19個產業之間的相互影響。樣本資料為主計處公布國內各業生產毛額,資料期間從1981年至2011季資料。本文所使用的研究方法為向量自我迴歸,以此估計未來一至五期的外溢表 (spillover table) 並計算外溢指數 (spillover index) 。實證結果顯示,隨著時間向前期數增加,外溢指數亦呈現增加的現象,表示產業之間的關聯更為緊密。

並列摘要


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.
