由本文問題的提出與解答可知，產業關聯數rij受產業內交易處理方法的影響，更有甚者，rij並與其對應的國內生產x1成正比。另外，利用毛產值法處理產業內的交易，會造成rji≥2，違背Dorfman-Samuelson-Solow說法，殊不合理。有鑑於此，本文乃利畢產業關聯特性乘數ρij，以改進產業關聯分析的數量模型與價格模型。

Based on the questions raise and answers given in this paper, it is found that the interindustrial multiplier rij is affected by the treatment methods of intraindustrial transactions, moreover, rij is always in proportion to its corresponding domestic output x1. Another finding is that using gross output method to deal with intraindustrial transactions causes rij≥2, dissatisfies Dorfman-Samuelson-Solow statement, and is unreasonable. In view of these facts, the author tries to use the interindustrial characteristic multiplier ρij to refine both the inter-industrial quantity and price models.
