| 摘 要： | 利用不动点理论给出了静态非线性投入产出模型解的存在性及唯一性的更为宽松的条件，它只要求直接消耗系数阵中的元素或单增或单减；同时给出了相应的两侧逼近迭代算法。

| Abstract: | A mild condition for the existence and uniqueness of the solution of static non linear input output model is presented by employing the fixed point theory. It is only required that the element of the direct input coefficient matrix should be mono increasing or mono decreasing. A two side approximation algorithm is also presented. |

| Keywords: | non linear/input output model fixed points existence |
