Oil has long been viewed as a strategic resource for nations. China is now the world’s second largest oil-consuming country after the U.S.. Its global efforts to secure oil imports to meet increasing domestic demand have profound implications for international relations in the Asia-Pacific region. China’s rising oil demand and its external quest for oil have thus generated much attention. As China’s overseas oil quest intensifies, will China clash with the U.S. and other western countries’ interests in Africa, and how dose it look at this rivalry? Will China disrupt the U.S. and its allies’ foreign policy and the world order? This article tries to provide an overview of China’s initiatives in developing oil in Africa. It examines factors for Chinese oil companies going to Africa and China’s oil strategy there. Finally, it argues that even though China’s practices of energy diplomacy in Africa seem to undermine U.S. goals of isolating or punishing “rogue states”, contrary to those pessimistic views, China has largely accommodated the U.S. and is willing to forge joint efforts with the U.S. in energy exploration in Africa.  相似文献

In the late 1980s, the Soviet Union was the world's largest hydrocarbon producer. The landmass over which these resources are distributed is vast and the reserves mostly landlocked. To convey these hydrocarbons to refineries and to market, the Soviets constructed the largest integrated pipeline networks in the world. After the dissolution of the Soviet Union, new competing national interests have produced tensions over these energy resources and transmission corridors, with economically detrimental and often irrational consequences. In Central Asia, the post-Soviet Republics of Turkmenistan, Kazakhstan and Uzbekistan produce significant amounts of hydrocarbons and export their oil and gas to or through Russian Federation territory. Russian government policy aims to continue exercising political control over these resources and to maximize Moscow's share of profits from their export. This paper examines oil and gas transmission issues in Central Asia, against a backdrop of emerging new relationships between the Russian Federation and the three post-Soviet republics, the resurgent strategic competition between Russia and the United States, China's developing power base in the region and Iran's potentially key geographic position for channelling Caspian energy supplies towards the Persian Gulf.  相似文献

In the public sector, innovation is understood as a major driver of public service performance improvement and excellence. On the one hand, previous research has proven a positive effect of innovation adoption on performance in the public sector. On the other hand, a broad literature proves positive effects of innovation antecedents on innovation adoption. This study bridges this gap and analyses the effect of an innovation antecedent – willingness to adopt a process innovation (accrual accounting) – on municipalities’ service provision cost-efficiency. Therefore, the author makes use of a panel data set of German municipalities, located in the federal state of North Rhine-Westphalia. Evidence shows that a higher municipal willingness to innovate relates to higher cost-efficiency. A higher innovation willingness might have a maximal effect of 17 percentage points on municipality cost-efficiency.  相似文献

新的《刑事诉讼法》增加了"技术侦查措施"一节,从程序法的高度完善了公安机关侦查工作的合法化,兼顾了打击犯罪与保障人权的价值追求。该文在总结毒品犯罪案件特点、重新界定技术侦查措施概念的基础上,对公安边防部门适用技术侦查措施侦办毒品犯罪案件的优势进行了阐述,以期更好的指导实践。当然,《刑事诉讼法》中技术侦查措施的规定并不是尽善尽美的,如何更好地完善技术侦查措施理应引起我们更多的思考。  相似文献

This article traces the changing funding relationships between Scotland and the UK government. Beginning from the Barnett Formula, it examines how the changing support within Scotland for greater political autonomy from Westminster has influenced the mechanisms that have determined Scotland's fiscal structure. Increasing support for the SNP, and then for the Yes campaign in the September 2014 independence referendum, has led to a mixture of new powers being granted to the Scottish Parliament. The Scotland Act 2012 extends the Scottish government's control over income tax and some other small taxes. Although independence was rejected by the Scottish people in September 2014, the ‘Vow’ made by the Westminster parties immediately before the vote is leading to far‐reaching changes in the UK's fiscal structure. This will cause a very substantial change in intergovernmental relations within the UK, which the Barnett Formula may not survive.  相似文献

法务会计与司法会计之比较   总被引:5,自引:0,他引:5  
知识经济时代已向我们快步走来,它将促使整个社会法制化的逐步完善。面对法制化社会的挑战,欧美各国于二十世纪先后开创了司法会计与法务会计,以应付日益严重的法制问题。在我国,法务会计应作为全面、正确贯彻新《会计法》的一个重要措施。通过分析法务会计与司法会计在中西方发展的现状,就法务会计与司法会计的联系与区别进行详细阐述,以期推动我国法制工作更上一个新台阶。  相似文献

俄罗斯石油工业10年来走过了一条从国家垄断到放开市场、到无序竞争,又从无序竞争到国家调控、规范市场的道路,逐步走上了稳定发展的轨道。经过数年的市场整合,俄石油工业基本上形成了以十几家大石油公司为主、150家中小石油公司为辅的格局。未来,应改变目前的小石油公司过多,世界级石油公司太少的局面,必须实行联合,以便与世界石油巨头竞争。  相似文献

西部地区经济发展滞后的主要原因是其所拥有的地缘困境。要改变这种地缘困境,重要的是找到促进地缘要素变化的主要中间变量。在其他条件不变的情况下,交通、通信和教育是推动地缘要素变化的主要的中间变量。发展交通、通信和教育是西部地区变地缘困境为地缘优势的关键所在。  相似文献
