Despite the entry into force of the Kyoto Protocol, the US decision not to comply with its Kyoto commitments seems to drastically undermine the effectiveness of the Protocol in controlling GHG emissions. Therefore, it is important to explore whether there are economic incentives that might help the US to modify its current decision and move to a more environmentally effective climate policy. For example, can an increased participation of developing countries induce the US to effectively participate in the effort to reduce GHG emissions? Is a single emission trading market the appropriate policy framework to increase the signatories of the Kyoto Protocol? This paper addresses the above questions by analysing whether the participation of China in the cooperative effort to control GHG emissions can provide adequate incentives for the US to re-join the Kyoto process and eventually ratify the Kyoto Protocol. This paper analyses three different climate regimes in which China could be involved and assesses the economic incentives for the major world countries and regions to participate in these three regimes. The main conclusion is that the participation of the US in a climate regime is not likely, at least in the short run. The US is more likely to adopt unilateral policies than to join the present Kyoto coalition (even when it includes China). However, a two bloc regime would become the most preferred option if both China and the US, for some political or environmental reasons, decide to cooperate on GHG emission control. If the US decides to cooperate, the climate regime that provides the highest economic incentives to the cooperating countries is the one in which China and the US cooperate bilaterally, with the Annex B?US countries remaining within the Kyoto framework.  相似文献

法学研究的经济学维度——基于法律经济学的思考   总被引:1,自引:0,他引:1  
李树 《现代法学》2003,25(6):45-48
法律经济学作为经济学帝国主义的重要表现 ,它是用经济学的方法和理论来考察、研究法律和法律制度的形成、结构、过程、效果、效率及未来发展的学科 ;它是法学和经济学科际整合的边缘学科。本文在阐述了法律经济学的发展历程及基本理论思维后 ,提出了法律经济学运动带给我们的几点思考  相似文献

科学发展观——我国公共政策评估的首要标准   总被引:4,自引:0,他引:4  
公共政策评估标准是开展公共政策评估的前提。为了更有效、更科学地开展公共政策评估活动,应设立正确的首要标准。科学发展观标准应当成为我国公共政策评估的首要标准。科学发展观标准是对以往我国公共政策评估标准的纠正和完善,符合我国社会主义国家公共政策的本质要求,顺应公共政策的发展趋势。坚持科学发展观作为我国公共政策评估的首要标准能有效提升我国公共政策质量,推进我国社会主义和谐社会建设进程。  相似文献

治理理论是当今世界上颇具代表性的新型国家——社会关系架构和公共事务管理模式,也是认识刑事政策体系中民间社会与官方(国家)在犯罪抗制场域界分时的重要分析工具。运用这一工具可以看出,民间社会与官方(国家)在刑事政策体系中存在着专治与共治领域的治理分工。其中,专治领域是国家保有的专属犯罪抗制场域,共治领域则是官方(国家)与民间社会合作抗制犯罪的开放空间。同时,在共治领域中,官方(国家)与民间社会应形成协同支持、国家主导的伙伴关系。  相似文献

Despite high revalence rates of intimate partner violence in the lives of extremely poor women with dependent children, few studies have investigated the patterns of violence that occur over time, and the characteristics of women that serve as risk markers for partner violence. This paper describes patterns of domestic violence longitudinally and uses multivariate analyses to delineate childhood and adult risk markers for recent intimate partner violence in this population of women. Analyses draw upon a sample of 436 homeless and extremely poor housed mothers receiving welfare, in a mid-sized city in Massachusetts with a large Hispanic population of Puerto Rican descent and relatively fewer Blacks. We found that among women with complete longitudinal data (N=280), almost two-thirds experienced intimate partner violence at some point during their adult life by the end of study follow-up, and that the abuse before and after the baseline interview was episodic and limited over time. To examine the role of individual women's factors, while controlling for partner characteristics, we used baseline data on women who had been partnered during the past year (N=336). Among childhood predictors, we found that sexual molestation contributed most significantly to adult intimate partner violence that occurred during the past year prior to the baseline interview. Adult risk markers included inadequate emotional support from non-professionals, poor self-esteem, and a partner with substance abuse problems. Having a partner with poor work history was another independent predictor of recent abuse. Ethnicity did not significantly predict whether women were abused or not during the past year, contrary to other findings reported in the literature.  相似文献

长期以来,台湾问题一直是影响中美关系正常发展的关键问题之一。然而,美国对华政策的基本取向始终是将台湾视为不享有主权国家之名的独立的“政治实体”。美国为了其亚太战略乃至全球战略利益考虑,不遗余力地为台湾“拓展国际空间”和制造“双重承认”创造有利的外部环境。正是由于美国的支持和纵容,台湾当局在处理两岸关系上,已经逐渐背离了“一个中国”的基本原则,其“台独”的反动嘴脸昭然若揭。  相似文献

为检测胰岛素样生长因子(IGFs)及其受体(IGFR)mRNAs在绵羊发情周期早期卵巢、子宫和输卵管中的表达,探讨绵羊胚胎早期发育过程中其发育环境——生殖道中生长因子的表达、分泌及其作用,取绵羊发情周期早期卵巢、子宫和输卵管,经固定、切片、免疫染色,观察IGFs mRNAs的表达和分布情况。同时用RT-PCR技术研究了各组织中IGF-Ⅰ、IGF-Ⅱ、IGF-ⅠR、IGF-ⅡR mRNAs的表达情况。结果表明,IGFs mRNAs在绵羊发情周期早期的卵巢、子宫和输卵管中都有表达,4种因子表达模式相似:在卵巢中,IGFs主要定位于卵泡颗粒细胞,间质细胞亦有少量表达。在输卵管中,上皮细胞免疫染色呈阳性;在子宫中,腺细胞及上皮细胞的阳性信号强于固有层。RT-PCR检测表明IGFs mRNAs在3种组织中均有表达。  相似文献

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might reap the environmental benefits of international agricultural trade.  相似文献

晚清时期,国门初开,护照制度开始实行。一般来说,护照是一个政府控制入境外国人的最基本、最有效的行政手段,本文拟对晚清政府关于来华外国人所持游历执照的政策作一概述,包括游历执照的分类、主要内容和实施的成效情况。此种游历执照,亦称"护照",但与现代意义上的"护照"有很大区别,是专门注明前往内地游历的通行证件,也起证明持照人身份的作用。  相似文献
