布尔加斯——亚历山德鲁波利斯管道项目可使俄罗斯达到一石二鸟的目的。这个管道项目不仅有助于俄罗斯向国际市场寻求增加石油供应,而且可提供一条与BTC输油管线相对应的、可供选择的管道路线。 相似文献

尤科斯事件后俄罗斯石油工业的新格局 总被引:2,自引:1,他引:2
石油工业是俄罗斯经济的主导部门之一。从俄罗斯经济发展的长远战略考虑,俄在较长时期内还将主要依靠能源产业,因此,必须对这个关系到经济发展前景的产业加强国家的掌控力度,通过对石油工业格局重新调整,加大国有股份的比重。目前,俄官方、媒体和专家达成的共识是,可能会存在四五家大型能源公司。俄罗斯东西伯利亚和萨哈林地区拥有丰富的碳氢化合物资源,正在积极寻求国际合作,以对产地进行勘探和开发。这为中俄能源合作提供了契机。 相似文献

《政策研究评论》2018,35(2):280-301
Prior research on policy conflicts indicates a tendency among policy actors to misperceive the influence of actors engaged in policy debates based on the degree of distance between their relative policy positions. This research develops a measure for assessing the degree and direction of the misperception effect. This measure is then utilized as a dependent variable to assess the relationship between theoretically relevant factors and the degree to which actors will exaggerate the influence of their opponents and allies. The research uses original survey data of policy actors engaged in the debate over hydraulic fracturing in New York. The results indicate misperceptions of relative influence are prevalent and most associated with the experience of a policy loss and holding relatively extreme policy beliefs. The findings provide new insight into factors that influence the demonization of political opponents. These insights are timely in the context of polarized debates over environmental and energy policy in the United States. 相似文献

Cultural Penetration and Punctuated Policy Change: Explaining the Evolution of U.S. Energy Policy
下载免费PDF全文

Punctuated equilibrium theory (PET) suggests that the policy process is characterized by long periods of incremental change and short periods of punctuated change. The impetus for the latter is usually a focusing event that breaks open policy monopolies, allowing for major changes in legislative decision making. While a burgeoning body of literature, a shortcoming in the PET literature is that it has yet to explain why focusing events and subsequent breakdowns in policy monopolies sometimes fail to result in punctuated policy. We integrate theories on cultural change with punctuated equilibrium to explain why focusing events do not always result in the dramatic policy changes that we might expect. Specifically, we use the context of national energy policy and the lexical database, Google Ngram Viewer, to trace punctuating energy‐related events and the occurrence or lack thereof subsequent policy change from 1952 to 2000. 相似文献

The American electric utility industry is entering a moment of transition. Once viewed as a stable and secure consortium of
publicly regulated monopolies that produce and distribute electricity, the industry has weathered market restructuring only
to face the ever-present risk of natural disasters, price fluctuations, terrorist attacks, and blackouts. This paper uses
five criteria—technical feasibility, cost, negative externalities, reliability, and security—to evaluate the broad portfolio
of energy technologies available to American electricity policymakers. Upon close inspection, energy efficiency practices,
renewable energy systems, and small-scale distributed generation technologies appear to offer many advantages over large and
centralized nuclear and fossil fueled generators. Contrary to the mimetic commentary produced by the media, these three approaches
would present policymakers a superior alternative for curbing electricity demand, minimizing the risk of fuel interruptions
and shortages, helping improve the fragile transmission network, and reducing environmental harm 相似文献

How does the American public assess risk when it comes to national security issues? This paper addresses this question by analyzing variation in citizen probability assessments of the terrorism risk of nuclear power plants. Drawing on the literature on how motivated reasoning, selective information processing, and domain‐specific knowledge influence public opinion, we argue that heterogeneous issue preferences and knowledge of nuclear energy and homeland security have important explanatory power. Using original data from a unique 2009 national survey in the United States, we show that Americans are divided in their probability assessments of the terrorism risk of nuclear power plants. Consistent with our theoretical expectations, individuals who support using nuclear power to meet rising energy demands, who are generally less concerned with terrorism, or who are more knowledgeable about terrorism and nuclear security tend to provide lower assessments of the likelihood that nuclear power plants increase terrorist attacks, and vice versa. The findings have implications for the literature on public opinion, risk assessment, energy policy and planning, and homeland security. 相似文献

文化研究的基本思路大致可以这样概括 :1 文化首先是一个特定群体共同拥有的意义系统 ,它最基本的功能就是确立和强化一个特定群体 ;文化发展的途径是通过个体与群体的冲突 ,生成新的符号系统 ,乃至生成新的内在法则。 2 文化是一个开放的能量交换系统 ,它服从于热力学第一定律和热力学第二定律 ;任何文化现象都是直接或间接地根据这两个定律服务于能量的转换 ;心理能量是能量摄取和转换水平的关键 ,但是心理能量的开发不是技术性的 ,而是象征性的。 3 人文科学的非线性特征 ,要求田野工作应该是一个多学科专家共同参与进行的系统工程 相似文献

Although officially Russian state-owned energy companies operate as independent entities, their actions often lead to suspicion that they are acting as a tool of Russian state foreign policy. Countries on the southeastern borders of Europe – Bulgaria and Greece – are prime examples of where this might be the case, since they not only have a central position in Russia’s plans to penetrate European markets through new transport infrastructure but are also part of competing plans for routing non-Russian gas to Western markets. The main focus of the present research is on the natural gas and oil sectors, as these are the traditional foundation of Russian energy exports to Europe. The aim of this paper is thus to provide an objective, evidence-based analysis of Russian activities in the natural gas and oil sectors of Greece and Bulgaria in order to establish whether its actions have been implicitly or explicitly politicized and have served to strengthen Russian influence in the region. 相似文献

The so-called ‘nexus’ approach has recently been promoted as addressing externalities across the water, food and energy sectors, thus helping to achieve ‘water/energy/food security for all’, ‘equitable and sustainable growth’ and a ‘resilient and productive environment’. While these are noble goals, this article argues that the reality on the ground appears to be taking a different direction, at least when it comes to China and its neighbours in South and Southeast Asia. There, a new era of large-scale water infrastructure development is creating several security-related problems, which represent serious challenges to the nexus goals. These challenges include food–energy tensions, human security threats and ecological risks. These challenges can also be linked to rising friction surrounding the management of water, food and energy resources in the region. The article argues that, in order for the nexus goals to be achieved in China and the countries on its southern periphery, there must first be increased awareness of this nexus among policy-making elites. 相似文献
