西方矿产技术经济评价模式

Economic Evaluation Techniques in Mining Investment Decision

在西方市场经济和矿产政策环境下 ,矿业作为一种商务活动毫不例外地服从市场经济的运行规则。矿业公司作为投资者在其投资决策过程中必须解决三个基本问题 ,即 :找什么矿 (市场 ) ,在哪里找矿(勘查 ) ,找什么规模的矿 (开发、生产 )。矿产经济评价作为一种手段在矿产投资决策过程中起非常重要的作用。矿产经济评价主要以现金流量和资金的时间价值为基础 ,考虑到税制因素和通货膨胀的影响 ,得出一系列静态 (总收益、项目规模、相对成本、返还期 )和动态 (年等值、净现值、现值比、回报率 )的经济指标。然后将地质、工程、市场和政策法规等信息作为一个“输入”变量 ,对矿业项目进行期望值分析、敏感度分析和风险度分析 。

Under the western market economy and mining policy system, there is a series of economic evaluation techniques for mining investment decision making. One of the most effective evaluation technique is discount cash flow method. Associated with mining taxation and inflation factors a set of economic criteria can be carried out by the evaluation, which includes relative cost, payback period, equivalent annual value, net present value, present value ratio and rate of return. With the variables of relevant geology, engineering, market and government policy, those economic criteria are applied to conduct expected value, sensitive, risk analysis, which will ultimately support the investment decision.
