俄罗斯天然气工业股份公司作为国有的天然气生产商,拥有俄罗斯48万亿立方米天然气储藏量中的11.1万亿立方米,并占世界天然气产量的19%和俄罗斯天然气产量的85%。该公司向欧洲出口天然气1470亿立方米/年,并向国内市场供应天然气。 相似文献

由于未能就2009年天然气供应价格和过境费用等问题达成一致,俄罗斯天然气工业股份公司(Gazprom)在2009年新年第一天便完全中断了对乌克兰的天然气供应。1月7日,俄方又以乌克兰无法足量保障天然气输往欧洲为由,中断了经乌克兰向欧洲的供气。这次“断气”至少使欧洲18个国家的天然气供应受到不同程度的影响。 相似文献

服务业外商直接投资可分为生产性服务业外商直接投资和消费性服务业外商直接投资,二者对国家经济增长有着不同的影响。本文从技术进步的角度,利用面板模型,研究了我国不同类型服务业外商直接投资对经济增长的影响,并分别讨论了东西部地区服务业外商直接投资对技术进步和经济增长的差异性影响。研究结果表明生产性服务业外商直接投资对经济增长和服务业技术进步均有明显促进作用,消费性服务业外商直接投资对经济增长有促进作用,但对服务业技术进步有阻碍作用,且这一趋势在我国东西部地区之间存在显著差异。 相似文献

This research evaluates the frontier National Telecommunication Program (NTP) in Taiwan using the data envelopment analysis approach and analyzes the influence of team communication and structure on R&D performance by establishing a structural equation modeling relationship. The results show that team communication is highly correlated with R&D performance. The high‐scored projects have internal communication patterns with a higher meeting frequency but shorter dialogue duration, a uniform distribution of regular meetings, a scheme for the lower hierarchy to meet with the project leader, a well‐managed channel to access accumulative expertise, and an open forum for communication. They also have external communication patterns with a gatekeeper bridging inward and outward information, a lower frequency of time‐consuming external sourcing, and a higher frequency of external cooperation, referencing, learning, and benchmarking. Though team structure has no significant influence on R&D performance, the high‐scored research group focused more on the structural dimensions of research strategy, laboratory management, and motivation incentives. This research will provide effective principles of project management to team leaders and industrial policy guidelines to program sponsors. 相似文献

We argue that foreign firms operating in a host country generate information spillovers that have potential value for later foreign direct investment. We test two predictions. First, we expect foreign direct investments by firms with experience in a host country to be more likely to survive than investments made by first-time entrants. Second, foreign direct investments will be more likely to survive the greater the foreign presence in the target industry at the time of investment, subject to two contingencies. The first contingency is that the relationship will be weak or nonexistent among firms with no experience in the host country, because these firms have difficulty evaluating and taking advantage of the information spillovers. The second contingency is that the presence of other foreign firms will not affect investment survival among firms that already have a presence in the target industry and undertake expansion. These firms already possess general information about the target industries and are unlikely to gain additional benefit from information spillovers. We find supportive evidence based on the survival to 1992 among 354 U.S. investments undertaken by foreign firms in manufacturing industries during 1987. © 1997 John Wiley & Sons, Ltd. 相似文献

本文选取长江三角洲41个地级市作为研究对象,基于近20年的面板数据,将产业结构、对外贸易和碳排放结合在一起,分析长三角地区碳排放空间特征,采用空间邻接权重矩阵、地理距离矩阵和经济距离矩阵结合空间杜宾模型探究产业结构、对外贸易与碳排放的联系。研究发现:(1)长三角地区碳排放量存在显著的正空间相关性;(2)从直接效应来看,产业结构高级化和产业结构合理化会抑制本地区碳排放量的增长,但会增加邻近地区的碳排放量;(3)对外开放水平的提高会增加本地区和邻近地区的碳排放量。 相似文献

据海关数据统计显示,2010年上半年我国玩具出口75.7亿美元,同比2009年上半年累计出口下降了2.55%(2009年上半年出口77.7亿美元,全年出口198.3亿)。不过值得注意的是,从4月开始,受采购季节因素的影响,出口数据呈明显上升趋势,5月、6月单月出口总额已经超过2009年同期,据部分省市区7月份的数据来看,2010年下半年将延续增长趋势。 相似文献
