摘　　要：在投入产出分析中 ,对宏观经济模型直接消耗系数矩阵的不可约性、本原性及其标准幂极限的存在性之间的关系 ,给出了一个充分必要条件 ,并就一般情形进行了讨论。In input-output analysis, relations between the primitive characteristic and the standard power limit of nonnegative irreducible square matrix in the direct consumption coefficient matrix of the macroeconomic model has been studied. A sufficient and necessary condition is given. A general state has also been discussed.
