中国煤炭市场现状剖析与国际煤价走势研究

近年来我国己成为世界第一煤炭生产国、消费国和进口国.2013年实施电煤价格并轨后,我国国内煤价与国际煤价的波动趋势也将日趋一致.在国内煤炭供给过剩的情况下,我国煤炭进口却仍在大幅增加,对我国煤炭市场造成了较大影响.因此,准确预测国际煤炭价格既有利于择机进口煤炭,也有助于进一步完善国家煤炭应急储备机制.通过整体经验模态分解(EEMD),非平稳煤价序列被分解重组为正常市场波动、重大事件影响、长期趋势等具有不同经济含义的时间序列.这三项时间序列被用于支持向量机(SVM)组合建模对国际煤价进行了一年内短期预测.研究发现:2013年国际煤炭价格将呈整体下跌趋势,趋向长期趋势线,并处于低位小幅波动.

A Conceptual Analysis of the Application of Tradable Permits to Biodiversity Conservation

Abstract: Tradable permits have been applied in many areas of environmental policy and may be a response to increasing calls for flexible conservation instruments that successfully conserve biodiversity while allowing for economic development. The idea behind applying tradable permits to conservation is that developers wishing to turn land to economic purposes, thereby destroying valuable habitat, may only do so if they submit a permit to the conservation agency showing that habitat of at least the equivalent ecological value is restored elsewhere. The developer himself does not need to carry out the restoration, but may buy a permit from a third party, thus allowing a market to emerge. Nevertheless, the application of tradable permits to biodiversity conservation is a complex issue because destroyed and restored habitats are likely to differ. There may be various trade‐offs between the ecological requirements that destroyed and restored habitats be as similar as possible, and the need for a certain level of market activity to have a functioning trading system. The success of tradable permits as an instrument for reconciling the conflicts between economic development and conservation depends on the existence of certain economic, institutional, and ecological preconditions, for example, a functioning institutional framework, sufficient expert knowledge, and adequate monitoring and enforcement mechanisms.     

On Population Mobility in Market Economy

A general survey of the changing process of economic development of human society indicates three historical development stages: agricultural-oriented natural economy, industrial-oriented market economy and knowledge- oriented market economy.

论我国城市污水处理市场化过程中的政府职能

近来我国城市公用事业的市场化改革正在快速发展，但污水处理作为城市公用事业的，市城化改革进展却十分缓慢，绝大部分城市的污水处理行业仍在传统的政府断经营的轨道上运行，本文从我国现实出发，认为政府职能未能及时调整是导致改革进展缓慢的重要原因，提出必须以市场为导向定位政府职能，充分发挥市场机制在污水处理中的作用，并通过重点培育和完善市场及市场机制，加快城市基础设施建设投资体制改革，加强污水处理监管体制建设等措施，推进污水处理市场化改革，这对我国政府导推进城市其它公用事业市场化改革无疑具有重要的借鉴意义。     

Consideration of some key issues of carbon market development in China

The global carbon market has developed rapidly with two significant trends of globalization and financialization.Deriving economic interest is a nation driven-force behind the international climate negotiation and carbon market.According to deeply analyzed relationships between the carbon market and the key subjects of the climate negotiation,this article reveals that promoting the development of the global carbon market is one of the core interests of developed nations.Based on the background of international carbon market development and domestic carbon market pilots,four suggestions to the key issues of China’s carbon market are provided.The first is that the goal of China’s carbon market should be in line with and contribute to the national objectives and policies addressing climate change.The second is that the Chinese carbon market should mainly target the emission reduction of production-sectors,and contribute to their upgradation and transformation.The third is mat the development of the nation-wide carbon market in China should first take the principle of unbalanced regional development into consideration.The fourth is that linking China’s carbon market to the international market should keep steps in line with international opening-up of China’s financing system.     

产权性质、市场竞争与企业社会责任行为——基于政治寻租视角的分析

无论是古典经济学理论、社会契约理论还是利益相关者理论,似乎都缺乏了一个重要的元素:政府行为以及政治、经济体制的影响,而只是将政府作为一个仅仅取得税收收益的利益相关者纳入我们的分析范畴,忽视了不同政治体制下政府构成了企业生存重要环境的特殊事实,这样的淡化直接影响我们对企业社会责任行为的实然理解。根植于西方社会的传统企业社会责任理论没有过多的考虑政府行为以及政治体制的影响,是基于其自身的制度背景与社会文化,它们是以高度自由的市场经济为基础,政府对经济(企业行为)干预很少,整个政治经济制度更加贴切新古典经济学的假设。而以中国为代表的新兴市场国家,政治经济体制改革和经济转轨使得制度环境对经济运行和企业决策有着重要影响,这为政治经济学理论的运用提供了制度基础,也为从政治经济学角度分析公司社会责任行为提供了研究机会。本文以我国2004年-2011年沪深股市的上市公司为研究样本,基于新政治经济学的寻租理论,研究了我国企业社会责任行为的寻租动机。研究的结果发现:我国企业社会责任行为呈现出明显的寻租倾向,而由于受到二元经济体制割裂的影响,相对于国有企业具有产权联系的先天优势,非国有企业社会责任行为表现出更为强烈的政治寻租倾向。实证研究同时也表明,产品市场竞争越激烈,企业寻租倾向越强。论文的研究构建了我国企业社会责任行为新的分析性框架,拓展了企业社会责任行为研究的相关文献。

Rhetoric and Reality of Water Quality Trading and the Potential for Market‐like Reform1

Stephenson, Kurt and Leonard Shabman, 2011. Rhetoric and Reality of Water Quality Trading and the Potential for Market‐Like Reform. Journal of the American Water Resources Association (JAWRA) 47(1):15‐28. DOI: 10.1111/j.1752‐1688.2010.00492.x Abstract: Many public interest groups, government agencies, and professional economists argue that current approaches to water quality trading are a cost‐effective, politically practical innovation for achieving water quality standards, in part by addressing one of the most difficult water quality improvement challenges – limiting the discharge from nonpoint sources. A critical analysis shows that these claims for current water quality trading programs are often unrealized. This rhetoric, without adherence to principles of market‐like reform, can undermine the support of regulated parties for meaningful water quality policy reform, contribute to missed opportunities to implement cost‐effective programs, and postpone successfully meeting the challenge of limiting nonpoint source discharges. A better understanding and application of market‐like principles can result in an improved design of trading as well as general water quality management programs.
