区域合作背景下服务业发展的收敛性研究——以大珠三角金融业为例     

钟韵  吴蒙 《热带地理》2015,35(2)

文章基于经济增长收敛理论,从区域合作视角,展开服务业发展收敛性研究.包括阐释服务业发展收敛的内涵、与经济增长收敛的关联、服务业发展的收敛机制,以及分析服务业发展收敛的模型与指标选择,并最终运用所构建的方法,对CEPA实施后大珠江三角洲的金融业收敛性进行了实证检验.结果显示,2004-2008年该区域金融业发展呈发散趋势.这一结果与近年来以其他方法与指标检验金融收敛性得出的结论基本一致,证实了基于经济增长收敛理论及分析模型的服务业发展收敛研究思路与分析模型具有可信性与可行性,亦从一个侧面对大珠三角金融合作的成效作出了评判.  相似文献   

Implementing adaptation in developed countries: an analysis of progress and trends     

FRÉDÉRIC GAGNON-LEBRUN  SHARDUL AGRAWALA 《Climate Policy》2013,13(5):392-408

Little attention has been paid thus far to the experiences of developed countries in adapting to climate change. This article addresses this research gap by providing an assessment of broad trends in progress on planning and implementing adaptation in developed countries. Primary inputs are the National Communications (NCs) by these countries to the United Nations Framework Convention on Climate Change (UNFCCC), although the article also discusses illustrative examples of recent adaptation activities that have not been covered in the NCs. NCs reflect ‘whole government’ perspectives and follow a standardized reporting format, which facilitates cross-national comparisons. The analysis shows that impacts and adaptation receive limited attention within NCs. The discussion on impacts and adaptation has typically been dominated by climate scenarios and impacts analysis, while the discussion on adaptation is often limited to the identification of generic options. There are signs of recent progress, however, in the Third and especially the Fourth NCs, in which a growing number of developed countries report on establishing frameworks for adaptation and on efforts to implement adaptation measures that take future climate into account. Although an encouraging sign, it is still too early to assess the eventual impact of such measures.  相似文献   

Delivering the two degree global climate change target using a flexible ratchet framework     

Hannah Ritchie  David S. Reay 《Climate Policy》2013,13(8):1031-1045

Global climate negotiations have been characterized by a divide between developed and developing nations – a split which has served as a persistent barrier to international agreement within the United Nations Framework Convention on Climate Change process. Notable progress in bridging this division was achieved at the 21st Conference of the Parties meeting in Paris through the introduction of Intended Nationally Determined Contributions (INDCs). However, the collective ambition of submitted INDCs falls short of a global 2°C target, requiring an effective ratchet mechanism to review and increase national commitments. Inequitable distribution of additional responsibilities risks re-opening historic divisions between parties. This article presents a flexible ratchet framework which shares mitigation commitments on the basis of per capita equity in line with emerging requirements for a 2°C target. The framework has been designed through convergence between developed and developing nations; developed nation targets are based on an agreed standardized percentage reduction wherever emissions are above per capita equity; developing nations are required to peak emissions at or below per capita equity levels by an agreed convergence date. The proposed framework has the flexibility to be integrated with current INDCs and to evolve in line with shifting estimates of climate sensitivity.

Policy relevance

The outcome of the 21st Conference of the Parties (COP21) negotiations in Paris offered mixed results in terms of level of ambition and submitted national commitments. A global agreement to keep average global temperature rise below two degrees was maintained; however, current pledged Intended Nationally Determined Contributions (INDCs) are projected to result in an average warming of close to three degrees. The implementation of a global ratchet mechanism to scale-up national commitments will remain key to closing this ambition gap to reach this two degree target. How this upscaling of responsibility is shared between parties will be a defining discussion point within future negotiations. This study presents a standardized, equity-based framework for how this ratchet mechanism can be implemented – a framework designed to be flexible for evolution in line with better understanding of climate sensitivity, and adaptable for integrations with current INDC proposals.  相似文献   

Commitments through financial options: an alternative for delivering climate change obligations     

《Climate Policy》2013,13(1):9-21

Governments willing to commit themselves to maintain carbon prices at or above a certain level face the challenge that their commitments need to be credible both for investors in low-carbon technology and for foreign governments. This article argues that governments can make such commitments by issuing long-term put option contracts on the price of CO₂ allowances. This mechanism gives investors the right, but not the obligation, to sell allowances to the government at the strike price. From the investors' point of view, a government is therefore fully committed to a price floor for allowances in the future. This proposed approach alters the incentives that a government faces when considering noncompliance and serves to prevent non-compliance. The proposal fares well when assessed against criteria to determine its suitability in legitimacy, enforcement, proportionality, lack of interference from other contracting States, and transparency. It also allows for fine-tuning through the number and duration of issued options and the strike price. A robust contract structure is proposed to protect against government interference that might threaten the credibility of commitments.  相似文献   

The impact of the unilateral EU commitment on the stability of international climate agreements     

《Climate Policy》2013,13(2):148-166

The negotiation strategy of the European Union was analysed with respect to the formation of an international climate agreement for the post-2012 era. Game theory was employed to explore the incentives for key players in the climate policy arena to join future climate agreements. A ?20% unilateral commitment strategy by the EU was compared with a multilateral ?30% emission reduction strategy for all Annex-B countries. Using a numerical integrated assessment climate—economy simulation model, we found that leakage, in the sense of strategic policy reactions on emissions, was negligible. The EU strategy to reduce emissions by 30% (compared with 1990 levels) by 2020, if other Annex-B countries follow suit, does not induce the participation of the USA with a comparable reduction commitment. However, we argue that the original EU proposal can be reshaped so as to stabilize a larger and more ambitious climate coalition than the Kyoto Protocol in its first commitment period.  相似文献

南海问题的大周边地缘环境   总被引：6，自引：1，他引：5  

胡浩  葛岳静  胡志丁 《世界地理研究》2012,(3):36-44

南海的西沙、南沙等历来是中国的领土,但如今海洋国土存在重大争议,南海已经成为世界上最复杂、最紧张的水域之一,南海周边的政治、军事、经济地缘环境也越来越为复杂。本文以南海问题为切入点,基于南海地理区位中的要素联系对南海周边国家的地缘环境进行探讨。结果得出:南海问题是涉及多元利益和跨国机构关联的复杂问题,南海周边是一个包含域内争端国家、域外干涉国家和具有复杂组织机构关联的"大"周边,南海周边地缘环境是超出地理毗邻的"大"地缘环境,中国南海的维权维稳势必要在域内双边地缘环境、域外多边地缘环境、国际多元多边地缘环境等构成的大周边地缘环境下做出战略决策。  相似文献
