| 摘 要： | 设Ｔ是某闭式Ｌｅｏｎｔｉｅｆ投入产出模型的投入矩阵，如果有正向量Ｘ使得Ｘ≥ＴＸ，则称该模型为可行的．本文给出闭式Ｌｅｏｎｔｉｅｆ模型是否可行的一个实用的判定程序．

| Abstract: | Let T be a consumption matrix of the closed Leontief input output model, which is said to be feasible if there exists a positive vector X such that X≥TX . In this paper, a practical determinant procedure for examining feasibility of the closed Leontief model was established. |
