These examples help explain why most environmental scientists believe that over the next few decades , the danger of degradation and exhaustion is greatest for potentially renewable resources , not nonrenewable resources ( except for petroleum and perhaps a few scarce minerals for which we can ' t find economically and environmently acceptable substitutes ) 这些例子有助于解释为什么大多数环境科学家相信在今后几十年内，可再生资源被退化和枯竭的危险性是最大的，而不是不可再生资源（石油，还有少数几种我们未能找到经济和环保的代替品的稀有矿物除外） 。
Retailers can cultivate their customer loyalty by establishing their accurate localization , providing best services and unique commodities , etc . the location of shops is the most important factor for customers to select desired shops , and furthermore , favorable locations of shops are deemed as irregenerated resources . long - term friendly and mutual benefit cooperative relations with suppliers formed by retailers are a competitive superiority for another round of cooperation . advance information management and sub - contribution systems can lead to a rapid response to customers " demand , reduce shortage possibilities for goods in stock , and keep the minimum inventory , by retailers 零诸售商通过准确的定位、提供良好的服务和独一无二的商品等方式来建立顾客忠诚;商店位置是顾客选择商店购物时所考虑的最重要的因素，而且，优越的商店位置是不可再生资源;零售商与供应商建立长期良好的互利合作关系是其另一长期竞争优势;先进的信息管理和分销系统使零售商能够对顾客的需求作出迅速反应，减少存货短缺，保持最低存货量;低成本经营对所有零售商都很重要，它使零售商在获得较竞争对手更高的边际利润的同时，能吸引更多的顾客。
From the inter - generational perspective of sustainable development , the utilization of non - renewable resources will be analyzed in this paper and the conclusion will be drawn that market failure exists due to inter - generational externalities . the current generation often over - utilizes the non - renewable resources for their own benefits , which damages the offspring , and thus government interference is needed . the government should take an active role in setting up sustainable consumption concept of non - renewable resources , completing market feature of allocating resources , boosting the reform of resource property right institution and the innovation of science and technology , to realize the object of sustainable utilization of non - renewable resources 本文以可持续发展的代际视角,从资源使用的代际外部性入手,对不可再生资源的可持续利用进行经济学分析:首先,对不可再生资源可持续利用的相关理论进行回顾与综述,旨在为下文的分析提供理论基础;其次,在对不可再生资源概念和性质进行界定和分析的基础上,指出不可再生资源可持续利用的意义;再次,通过外部性理论分析,指出代际外部性导致的市场失灵需要引入政府干预来进行矫正,此外,政府还应该积极地发挥在消费观念、产权制度和科技创新等方面的作用,从而实现不可再生资源可持续利用的目标;最后,在借鉴国外实践经验的基础上,针对我国不可再生资源利用的现状,给出了相应的政策建议。
After comparing the results of 10 simulation experiments , i make the conclusions : ( 1 ) in the evolutions of the horizontal and symbiotic industrial cluster basing on the natural resources , if the resources are limited , optimal scales will exist , but cannot last for long , for there is no reliver ; if not , it seems that the existence of optimal scales may not be pointed out 根据比较分析10个设计方案的仿真实验结果,本文得出结论: ( 1 )在依靠当地自然资源禀赋而形成的水平共生型产业集群的演化过程中,当资源受限时其合理规模存在,但不可持久,因为受不可再生资源约束;当资源无限时似乎看不出合理规模的存在。
These examples help explain why most environmental scientists believe that over the next few decades , the danger of degradation and exhaustion is greatest for potentially renewable resources , not nonrenewable resources ( except for petroleum and perhaps a few scarce minerals for which we can ' t find economically and environmently acceptable substitutes ) 这些例子有助于解释为什么环境科学家相信在以后的数十年里，退化和枯竭的危险是再生资源的最大危险，而不是不可再生资源（除了石油和一些可能的稀有矿石，因为我们不能找到经济而又适合环境的替代品） 。
Economics were related to the relation between economic activities and natural resources since its birth . following the logic of economic theory development , different perspectives of natural resources in classical economics , marxism economics , neo - classical economics and sustainable development theory are examined respectively 同时,要在充分发挥市场机制的调节作用、科技进步的基础作用以及政府的主导作用的基础上,通过这三方面作用的有机结合,最终实现不可再生资源的可持续利用。
The non - renewable resources is introduced into the production function , this paper formulated the optimum decision - making model of social planer , used the stochastic analysis method , analyzed optimum decision - making which the social planer about the expense and the non - renewable resources utilize under the indefinite condition , and obtained the optimum storage quantity of capital demonstration way and the density of stability distribution , and give the policy meaning of the model 摘要将不可再生资源引入生产函数构建了一个社会计划者的最优决策模型，运用随机分析方法，分析了不确定条件下社会计划者关于消费和不可再生资源利用的最优决策，得到了最优资本存量的显示路径及稳态分布密度，并给出了模型的政策含义。
