| 摘 要： | 用“竞争优势”，或采用线性规划及其对偶方法只能说明当“条件好的矿产”参与竞争时，它会被优先开采。但这却不能说明条件好的矿产持有者为什么不推迟他（ 她） 的矿产的开发日期，而采取在未来某一个合适时期开采的战略，以此获得更多的经济利益。本文用 Ｈｏｔｅｌｌｉｎｇ 平衡条件证明，先开发条件好的矿产，对条件差的矿产持有人有利，同时也对整个社会有利；而先开发条件差的矿产却对条件好的矿产持有人及整个社会均不利。

| Abstract: | Why should the society prefer extracting the best deposit?It seems self evident because in view of the extracting cost,the best deposit has some competitive advantages.The normal way for this question is to adopt a linear programming model.When all the market places and sales of the deposit are given,and its possible resource sites,production,unit product cost and the transportation cost between the resource sites and the markets are known,the linear programming and its solutions would indicate that extracting better deposits can minimize the cost of social product and transportation.At the same time,the dual of the model and its solutions also indicate that better deposits can exclude worse ones because of their lower shallow prices.However,this model can not explain why the owner of the best deposit does not delay the extracting date for this deposit,but to take a kind of strategy of some appropriate time in the future to make better profit .This article begins with Hotelling model and explains that to extract best deposit is good for all the deposit owners and the society,while that to extract worst deposit is bad for both the best deposit owner and the whole society.Then the owner would not delay to extract his best deposit. |
