| 摘 要： | 互为对偶的两个线性规划问题中，当基解不是一一对应时，就会产生矛盾：退化基不一定对偶退化；可行基不一定对偶可行；最优基不一定对偶最优．这对影子价格确定有重要影响，会出现多影子价格和无界影子价格问题．

| Abstract: | As far as the two problems in linear programming of mutual duality are concerned,the non-correspondence of the basic relation will result in contradictions:degenerate base does not necessarily degenerate in duality; feasible base may not be feasible in duality;the optimum base may not be optimal in duality. Those contradictions will greatly influence the ascertainment of the resources price,from which multi-shadow price and unbounded shadow price may arise. |

| Keywords: | dual linear programming basic relation degenerate shadow price |
