目前,煤矿建设仍然存在绿色生态投入动力不足的问题。本文首先指出了绿色生态矿山建设的现状,并运用外部性理论分析煤矿绿色生态投入不足的经济机理;最后,基于外部成本内化深入分析了外部影响因素对绿色生态矿山建设的影响机理。 相似文献

ABSTRACT: Traditional procedures for evaluating flood damages to residential dwellings do not reflect intrinsic values when applied to historic homes. Such structures are worth more than that determined by using depth-damage curves provided by insurance companies who assess damage values based upon current labor and material costs. The evaluation of the worth of a historic home and subsequent damages due to inundation can be regarded as a problem of externalities. An assessment technique reflecting historic amenities or what has been termed replication cost is proposed in this paper. Replication costs would have widespread use not only in solving flood dammage problems, but also in any study where historic entities are subject to damages from catastrophies such as hurricanes, soil and beach erosion, and increasing urbanization. If adopted as a technique, it would enhance and preserve the ever-decreasing enclaves of historic homes and neighborhoods. 相似文献

环境成本是指人类经济活动引起的环境损失。主流经济学认为,外部性与产权是产生环境污染的经济根源,减少环境成本的实质是通过一定的手段将环境成本内在化。不同的治理手段具有不同的治理成本,一般而言,经济手段具有更高的经济效率和较低的成本,但管制手段也有其存在的意义。解决我国的环境成本问题需要树立生态经济协调发展模式,让企业成为污染治理的主体,建立环境补偿机制等。 相似文献

生态公益林建设管理的环境经济政策分析--以广州市为例 总被引:3,自引:0,他引:3
根据环境经济学的外部性理论 ,生态公益林建设管理具有外部经济性。使生态公益林建设管理外部性内部化的主要手段是“调节市场”型的环境经济政策 ,即由政府向公众征收生态公益林建设管理费用 ,而“建立市场”型的环境经济政策———明晰生态公益林的产权、承包经营权 ,则是生态公益林建设管理外部性内部化和生态公益林有效管理的需要。广州市生态公益林建设管理中存在的建设管理资金不足、林地的使用权分散、对林农补偿的数量难以确定等问题 ,有待于上述两种环境经济政策来解决 相似文献

协调贸易与环境的最佳途径——环境成本内部化 总被引:4,自引:0,他引:4
面对经济发展带来人类福利增加的同时所产生的日益严重的环境污染问题。国际贸易被指责为环境质量下降的原因之一.甚至连国际贸易自由化的原则也受到质疑。围绕贸易与环境可否协调以及如何协调的问题.由环境保护与贸易自由化在理论和实践中的冲突引出贸易与环境之间存在着复杂的相互作用;并通过进一步的经济学分析得出结论:环境问题的根源并不是国际贸易。而是环境成本的外部性造成的市场失灵,而国际贸易只是加重了这种市场失灵。二者可以协调发展。环境成本内部化是解决这一问题的最佳手段。通过环境成本内部化可以达到环境资源的合理配置并最终实现可持续发展。 相似文献

代际外部性与不可持续发展的根源 总被引:11,自引:0,他引:11
赵时亮 《中国人口.资源与环境》2003,13(4):1-4
外部性是经济学者一直关注的问题之一,可持续发展概念的提出,事实上涉及到了外部性问题在时间上的表现,即表现为当代人行为对后代人带来的外部性。这将促使我们更加深入地思考外部性的涵义和外部性问题。以往经济学研究中常用的处理外部性行为的两个途径——庇古税和科斯定理,在面对由于主体缺失情况下的代际外部性时,表现得无能为力。本文认为,代际的外部性是不可持续发展的根源,应该成为可持续发展研究中的焦点。 相似文献

Toward Integrated Environmental Management for Challenges in Water Environmental Protection of Lake Taihu Basin in China 总被引:5,自引:3,他引:2
Lake Taihu is the third largest freshwater lake in China. It serves many social, economic, and ecological purposes in the
drainage basin. Unfortunately, the water has been heavily polluted due to rapid industrialization and urbanization during
the last two decades. Notwithstanding great efforts made so far to improve the water quality, the environmental situation
is still far from being optimistic. The basin and the lake are facing a range of severe environmental challenges: rapid socio-economic
development continues to place great pressures on the environment, current pollution control projects have many problems from
the viewpoint of effectiveness and efficiency of their implementations, and the non-point sources of pollution such as agricultural
fields, for which control is more difficult than for industrial point sources, have become the main contributors to serious
eutrophication of the lake. Considering the characteristics of the environmental challenges and problems confronting the basin
and the lake, we focus on integrated environmental management (IEM) as a promising and effective approach to overcome these
predicaments. Current practices and problems of environmental management in the basin are examined, and potential future developments
are discussed. Three aspects of the IEM are emphasized: institutional cooperation, public participation, and internalization
of environmental externalities. We think these are the most critical for not only the basin but also for the whole of China
to achieve a sustainable society. 相似文献
