能源领域的合作项目——尤其是管道合作——是上合组织多边合作的一个重要方向。于2009年底开通的“中国-中亚”天然气管道就是这种多边合作的新亮点。互利共赢是管道成功的理念基础,它不仅是中国能源安全的有力保障,同时也符合管道的起始国和过境运输国的国家利益。 相似文献

Africa is the world’s biggest battleground in the fight against hunger. African governments and the international development community have increasingly focused on finding ways and means to end hunger and ensure the right and access to food for the continent’s burgeoning population. Public spending on agriculture is one such measure. This study examines the role government spending on agriculture has played in enhancing the state of Africa’s food security over the past 25 years. We examine the existing relationship between the two, whether this relationship varies over time and space, and whether it depends on the amount spent. We explore various aspects of food security and check whether spending on research and development follows the same patterns as the overall public agricultural spending. We find some evidence of significant beneficial effects of public agricultural spending on food security but only for the countries which allocate greater proportions of their budgets to agriculture. Spending on agricultural research and development also shows a positive impact on Africa’s food security. There also exists some evidence supporting the temporal effects of public spending. We consider that the Maputo Declaration commitment to allocate at least 10% of public spending to agriculture pertinent. 相似文献

以行政问责、矿产资源整合、区域性停产整顿等方式遏制矿难,见效不大。矿主是安全物品供给主体,但缺乏强迫矿主为矿工提供安全与健康物品的制度安排。只生产矿产品不生产安全与健康物品,让矿工承担成本而矿主增加收入属于市场失灵,市场失灵时的政府管制应定性为保护矿工基本人权的社会管制,必须通过社会管制强迫矿主供给矿工享用的集体物品而阻止矿主的不当收入。 相似文献

Although the work of Clarence Ayres is held in high regard within the tradition of American Institutionalism, it has made little impact upon the study of technology more generally. Moreover, even within the Institutionalist tradition, his work is seen to embody a tension - on the one hand his dichotomy between technology and institutions is too strict, but to the extent that it is "softened," his main contributions are undermined. This paper argues that Ayres' work does have something to contribute to current technology debates, but that this contribution cannot be made if his conception is "softened" in the way that recent contributions suggest. 相似文献

This study examines chief executive officer (CEO) compensation and turnover in socially responsible (SR) firms. We compare characteristics of SR firms with a matched sample of firms based on industry and size. Analysis of CEO compensation indicates that the link between CEO pay and firm performance is weaker for SR firms than for non‐SR firms. CEO turnover tests indicate that SR firms are more likely to experience CEO turnover following poor performance. Stock option grants to CEOs of SR firms do not appear to result in future risk‐taking behaviour, whereas such grants are significantly related to future risk at non‐SR firms. 相似文献

This study examines how venture capital (VC) firms terminate investments in an emerging economy context. We contend that due to the weak institutional environment, it is appropriate to draw on insights from power and social relation perspectives for a better understanding of the phenomenon. Specifically, we argue that a termination decision hinges on not only the dependence relationship between a VC firm and its portfolio companies, but also the social relationships among VC firms. Event history analyses of approximately 12,000 VC deals made in China between 2001 and 2012 reveal that when a VC firm has a greater number of investments in an industry, it is more likely to terminate investments on a portfolio company in that industry. Moreover, such effect on termination is moderated by the focal VC's embeddedness with its syndicate partners and collaboration opportunities with other VC firms outside the immediate access of the syndicate partners. Our study sheds light on research on VC decision making in emerging markets by integrating insights from resource dependence relationships and interorganizational network characteristics. 相似文献

Growing evidence emphasizes the important role of network effects on bilateral trade. This paper proposes a new factor – dialect difference, which decreases social network across regions, may increase transaction costs and thus shape interregional trade pattern. Taking China as an example, we use a gravity model considering network effects and provincial data from 1997 to 2009 to examine the effect of dialect difference on intra-national trade. We find that dialect difference has a significantly negative effect on interprovincial trade. Moreover, this paper explores the time dimension of the effect of dialect difference. We find that the negative effects of dialect difference on trade have been diminishing over time. Migration and the promotion of Mandarin have increased interregional cultural connections and thus mitigated the negative effects of dialect difference. 相似文献

经济转轨中自然垄断行业规制改革——竞争、所有制与激励机制选择 总被引:1,自引:0,他引:1
竞争与所有制改革是目前自然垄断行业规制改革的主要趋势.但原有的理论和经验都是针对发达国家而言,对于转轨国家如何协调经济转轨与自然垄断行业改革却没有现成的理论与经验.所以,本文从转轨国家自然垄断行业引入竞争可能性以及所有制改革模式的选择入手,研究在加入策略性激励机制后竞争与所有制模式的不同组合对自然垄断企业绩效的影响.研究发现,转轨国家自然垄断行业改革进程取决于转轨国家市场发育程度以及改革的初始条件;混合所有制的企业竞争模式比完全私有化的社会福利水平要高,也更适合于转轨国家自然垄断行业改革的所有制选择模式. 相似文献
