为确定级差地租,最好从所开采的矿床中挑选一个最坏的矿床,在地质勘探阶段,要按照与相邻预开采矿床相对应的参数确定最坏的矿床。这类矿床的储量开拓成本按自己的水准应是最高的,构成了资源价值的基础。这样,后来找到高品位矿床(最低的成本)的地勘企业,除了得到正常利润外,还可获得超额(地租)收入,但由于这种剩余收入不仅仅在矿床自然条件下的差异结果会产生,而且通过企业集体劳动努力 To determine differential rent, it is best to pick one of the worst deposits from the mines that are mined, and to determine the worst deposit by the parameters corresponding to the adjacent pre-mining mines during the geological exploration phase. The reserves of such deposits should be the highest according to their own standards and form the basis of the value of resources. In this way, the geological exploration enterprises that later found the high-grade deposit (the lowest cost) can obtain excess (rent) income besides normal profit, but as such surplus income not only results from the difference in natural conditions of the deposit, , But also through the collective labor of enterprises
