简直极少能有完全满足人类需要的资源,这就意味着社会在某一方面积极应用资源时,必须同时放弃在另一方面应用资源的机会。在考虑资源的最佳应用时,以经济效益为标准是必要的。牙科文献中,虽然对某种特殊疗法以成本—利润率好坏的描写是增多了,但是这些描写方法还没有公文化。对于一个防治计划进行成本—利润分析和成本—效果分析,则能很容易地搞清楚它的“经济效益”问题。 It is very rare to have resources that completely meet human needs. This means that when a society actively uses resources in a certain area, it must abandon the opportunity to apply resources in another area. When considering the best application of resources, it is necessary to use economic efficiency as a standard. In the dental literature, although the description of the cost-profit rate for a particular type of therapy has increased, these description methods do not have public culture. A cost-profit analysis and cost-effectiveness analysis of a control plan can easily identify its “economic benefits”.
