在土地利用规划中,对线性规划结果进行影子价格计算可以确定其结果在最优状况时,放宽某个约束条件(a_ijx_i=b_i)对目标函数（S）产生的附加贡献值。而敏感性分析解决了在线性规划仍保持最优解情况下,所允许的因市场条件和生产过程的改变导致的资源限制且（b_i）和利益系数（c_i）的可行变化范围。通过以上计算和分析,使静态的线性规划模型向动态模型方向迈进了一步。为其在一定空间和时间上推广应用开拓了余地。

In land utilization planning, to calculate the shadow price of the linear planning result may determine for the objective function (S) the additional contribution value produced by the result at the time of optimus state and when certain limiting condition (a_ijx_i=b_i) is relaxed. On the other hand, the sensitivity analysis solves the permitted feasible change scope of the resource restriction quantity (b_i) and the benefit coefficient (c_i). Here the change scope is brought about by the change of market situation and production process under the condition that the linear planning still keeps the optimum solution. As the above mentioned calculation and analysis, the static linear planning model is made to move a step forward toward the direction of the dynamic model. This expands the realm for it to be popularized and applied in a certain place and at a certain time.
