国库集中支付角度下行政事业单位内部控制研究

国库集中支付与内部控制具有内在的联系性,国库集中支付的目的就是加强对行政事业单位资金的监管,提高财政资金的使用效益。但是在实际运行的过程中,行政事业单位的内部控制并未实现国库集中支付的预期目标。论文立足于国库集中支付视角提出行政事业单位加强内部控制的重要性,剖析行政事业单位内部控制体系建设的原则,最后提出构建基于国库集中支付的内部控制体系的具体对策。     

Collusive Long-Run Investments Under Transmission Price-Caps

In the short run, constraints in the electricity transmission system may give market power to generators. This paper examines whether the constraints themselves are a long-run equilibrium outcome in a competitive environment. We show that independent transmission companies and generators can tacitly collude to raise prices to consumers and divide the resulting profits. We also show that price cap regulation does not prevent this behavior and may in fact contribute to it. The mechanism for collusion is that generators locate their plants so that a capacity-constrained transmission line lies between them and their consumer market. We show that this constraint-based collusion can be sustained in a static game without any punishment strategies.     

区域环境承载力的定量化探讨--以大连市为例

With the analysis of the connotation and charter of the regional environment's carrying capacity, this paper,firstly, establishes the index system on the base of the affecting factors. Secondly, this paper discusses the methods of the quantization of the environment's carrying capacity of Dalian. Finally, this paper predicts the changing tendency of the environment's carrying capacity.     

国内外水资源承载力的研究综述

随着能源危机的出现,资源环境问题逐渐成为各国经济学家和环境学家特别关注的问题.近年来,水资源短缺越来越成为各地经济发展的制约因素,面对这种情况,资源承载力概念的提出为资源与经济发展问题提供了一条新的研究途径.本文将国内外有关水资源承载力概念和量化方法的研究作一总体分析,结果表明:(1)国外对水资源承载力的研究较少,国内的研究大体可分为初始、发展、鼎盛和拓展四个阶段;(2)从横向比较来看,水资源承载力的研究在我国以近十年为盛.但研究多集中在资源学科领域和地理环境学科领域,角度大多是综合考虑多方面的影响因素,对一个地区的水资源承载力作出系统评价,并借助可持续发展的思想,应用已有的和创新的方法来解决水资源承载力的问题;(3)水资源承载力的研究在一定程度上是土地资源承载力研究的进步;(4)水资源承载力的研究较少考虑环境污染对水资源承载力以及整个社会系统的影响.在此基础上,本文最后对承载力在自然资源方面的研究作了小结和展望.     

The Change of Ecological Footprint and Its Effect on Sustainable Development in Beijing of China

Speeding up the environmental protection and construction is one of the major issues in ＂Greener Olympic Games＂ held in Beijing in 2008. Making a thorough study to find out the reliable measures to ecological resumption in Beijing has an important scientific and practical significance. It can provide scientific basis for making a better decision for ＂Greener Olympic Games＂ held in capital Beijing and development in harmony for society and economy, as well as management for ecological environment. By studying of change of ecological footprint from 1990 to 2003 in Beijing, the paper shows that ecological footprint per capita has a strong relativity with population and GDP, and both of the correlation coefficient between them is about 0.92, as well as the fossil energy land has a position in the lead in ecological footprint items. The study also shows that the ecological capacity per capita in Beijing occupied about 1.25% in global ecological capacity per capita. Began 1990, the ecological deficit in Beijing was about 0.72 hm2, which is at strong unsustainable development at present. Finally, the paper suggests social and economic structure should be adjusted as soon as possible, resources should be strengthen sustainable used and population increasing should be controlled strictly, as well as arable land also should be under control used for built-up areas. Simultaneity, the utilizing ratio of energy sources should be increased, and the consumption of energy sources and ecological deficit in Beijing should be reduced in order to speed up the society and economy development in harmony and sustainment.     

上海市生态可持续发展评价研究

本文利用生态足迹法对上海市1985～2004年的生态足迹和生态承载力进行了研究，结果表明上海市入均生态足迹和生态承载力分别由1985年的1．9340hm^2、0．1582hm^2逐年增加至2004年的3．0459hm^2、0．5805hm^2，一而同期的入均生态赤字也由1．7958hm^2上升到2．6656hm^2。同时计算了万元GDP生态足迹，并预测了2010年的入均生态足迹和生态承载力。最后得出，上海市入口对自然资源的利用逐年增加，目前已超出了自然生态系统的生态承载力范围，现有的发展模式是不可持续的。     

东北区域创新体系建设的行政协调体系研究

在对区域行政协调体系理论进行研究的基础上，通过研究借鉴“长三角”和“泛珠三角”以及发达国家区域行政协调机制的经验，对东北区域创新体系的行政协调模式、行政协调的组织架构以及各机构职能设计做出了初步的探索，并提出了一些具体操作建议。     

发展壮大县域经济的行政学思考

县域经济在我国的经济与社会发展中有着举足轻重的地位,发展壮大县域经济中的行政管理必须坚持以民为本的原则,发扬艰苦奋斗的作风;发展壮大县域经济必须处理好经济区域和行政区划的关系、省地县行政区域经济的关系、市场调节和政策引导的关系以及简政与放权的关系;要深化行政管理体制改革,创新公共行政体制,推进县域经济发展.     

芯钢管混凝土节点的芯管壁厚与节点承载力关系的数值分析

对一种已经通过试验研究的钢管混凝土结构的新型节点进行数值分析。这种节点将钢管混凝土柱的钢管在节点区间断,在节点区设置芯钢管,使梁中的纵筋在节点中直通、梁与节点区混凝土成为一体可靠的传递梁中的弯矩、剪力及轴力。本文利用数值分析弥补模型试验数量少的缺陷。选择不同芯钢管壁厚的节点模型进行非线性有限元分析,得出芯钢管壁厚对节点承载力的影响规律。分析结果表明芯钢管壁厚是影响节点承载力的主要因素之一。     

基于价值链的军事物流核心能力刍议

按照价值链管理的思想,可以把军事物流价值链分为物质价值链、采购价值链、知识价值链和信息价值链,依据对价值链的贡献,借助层次分析法等分析军事物流的能力要素,得出军事物流综合管理能力、整合能力、处理突发事件能力等三项基本核心能力,并对提升军事物流的核心能力提出了见解。
