Study on Sustainable Standard for Economic Valuing of Enviromental Resources

1.本研究侧重于环境资源可持续利用的经济标准。主要研究成果为环境资源的可持续利用。2.评价环境资源可持续利用的经济学方法有：MSY、Mey、动态Mey、折旧法和用户成本法。基于社会使用的环境资源量大于资源的最小再生产规模的假设，当最大蓄积量增长量等于使用量时，可获得最大可持续产量。MEY方法将经济因素引入MEY，动态MEI在MEY中加入时间因素，折旧是一种在资源再生产中投入折旧成本的方法。比较环境资源的使用量和增长量。当前者大于后者时，折旧成本通过乘以超过再生产时间…的资源减少量来计算更多ES市场价。假设资源使用的收益由无限收益(净收益)和用户成本组成，用户成本是一种需要用户成本的再投资以保持永远的净收益的方法。4.分析了上述方法的含义和局限性，并对它们作为环境资源可持续利用的标准的有用性进行了社会评估。MSY、MEY和Dynamic MEI假设对环境资源进行完美的监测，并确认有问题的生物资源大于其最小生殖大小。此外，个别物种可能依赖其他物种继续生存。因此，即使以可持续的方式使用一个物种，也很可能对其他物种产生不可逆转的破坏性影响。折旧法是有问题的，因为我们很难用短期市场价格来确定我们是否能准确地评估环境资源的长期再生成本。用户成本并不表现在生物和环境层面上的可持续性，而只是表现在收入层面上。较少

1.This study focuses on economic standard regarding the sustainable use of environmental resources. The main research result is presented as "Sustainable Use of Environmental Resources".2.Some economic approaches for evaluating sustainable use are MSY,MEY,Dynamic MEY,Depreciation, and User Cost.3.The MSY approach is as follows. Based on the assumption that the amount of environmental resources which society use is larger than the minimum reproductive size of the resource in question, the maximum sustainable yield is obtained, when the maximum volume of stock growth equals the volume of use. The MEY approach introduces economic factors into MEY.The Dynamic MEY adds the time factor into MEY.Depreciation is a approach that invests depreciation cost in the reproduction of resources. Compares the amount of use and growth of an environmental resource. When the former is larger than the latter, depreciation cost is calculated by multiplying the resource reduction in excess of reproduction tim … More es market price. Supposing that the income from resource use consists of infinite income (net income) and user cost, User Cost is an approach that calls for the reinvestment of user cost in order to maintain net income forever.4.This study analyzes their meanings and limits of the above approaches, socially evaluating them with regard to their usefulness as standard for the sustainable use of environmental resources. MSY,MEY,and Dynamic MEY assume perfect monitoring of environmental resources and a confirmation that the biological resources in question is larger than its minimum reproductive size. Further, an individual species may be dependent on other species for continued existence. Therefore even using a species in a sustainable manner may well have irreversible damaging effects on other species. The Depreciation method is questionable in that it is hard to determine if we can accurately evaluate the long-term reproductive cost of environmental resources using the short-term market price. User Cost doesn't show sustainability at the biological and environmental levels rather only that at the income level. Less
