Multinational corporations (MNCs) and other foreign firms can be conduits for technology and knowledge (T&K) transfer to host countries in the developing world. Most of the existing research focuses on T&K transfers through FDI and are drawn from Asia not Sub-Saharan Africa (SSA), although SSA is increasingly receiving foreign investment. There is a paucity of research that gives insights into project-level T&K transfer issues in SSA countries. Using the Ghanaian construction industry as an empirical focus, this article explores T&K transfer potential. The findings reveal significant weaknesses in T&K transfer across industry subsectors and between foreign and local firms. This arises from the potentially complementary but dissimilar resource and knowledge bases. The weaknesses are compounded by the absence of coherent government T&K development policies.  相似文献

Calculating the probability of the corresponding significance point is important for finite sample sizes. However, it is difficult to evaluate this probability when the sample sizes are moderate to large. Under these circumstances, consideration of a more accurate approximation for the distribution function is extremely important. Herein, we performed a saddlepoint approximation in the upper tails for the distribution of the sum of independent non‐identically uniform random variables under finite sample sizes. Saddlepoint approximation results were compared with those for a normal approximation. Additionally, the order of errors of the saddlepoint approximation was derived. © 2014 The Authors.

在经济全球化背景下,涉及知识产权的贸易越来越普遍,而现代国际贸易的特点之一,就是进口货物的商标权、专利权等无形的特许权伴随着有形货物的转移,因此,目前进口货物的特许权使用费成为中国海关估价难点之一.文章在综述我国现行特许权使用费海关估价规则的基础上,针对我国进口货物特许权使用费海关估价所面临的问题,着重就如何进一步完善进口货物特许权使用费海关估价,从海关估价技术、估价法规、估价制度、外部环境等四条路径进行了具体分析,并提出了相关建议.  相似文献

One of the main issues with the concept of ecosystem services is its absence on the ground in concrete operational decision-making contexts; that is, an implementation gap. In this study, we investigated if this gap could be overcome through the use of open-source data and free tools, and the adoption of a short-term participatory process. We tested these methods in the context of a project in the urban metropolitan area of Bordeaux (Communauté urbaine de Bordeaux: CUB) in France. The ecosystem services were defined using a participatory approach involving local stakeholders, and then selected scenarios were simulated to test the impact of various development or conservation plans. The study addressed three main questions: (1) Is it possible to adopt a simple methodological approach that overcomes the implementation gap through the development of a user-friendly and inclusive method? (2) What is the added value of a participatory approach? (3) With regards to four scenarios in this territory, what are the ES trends in the selected biophysical and monetary indicators, and will knowledge of these trends help planners to shape a sustainable trajectory for the territory?  相似文献

The number of Muslim literates in Islamic finance and conventional finance, particularly Islamic insurance, has grown tremendously, so has the number of academic and professional articles, books, and other monographs published in Islamic insurance profession. Despite Islamic insurance uniqueness based on Islamic values and philosophies, its emancipation aimed to compete or eradicate the conventional insurance at both academic and professional levels. Those monographs that were intended to replace their conventional insurance counterpart have triggered endless debates among stakeholders on their authenticity and quality of knowledge and as well challenged their authors' authorities. Therefore, with content analysis, this survey verified whether the Islamic insurance literatures were capable of producing well-seasoned professionals of lslamic insurance. The results showed that the disputes over the available literatures might have contributed to the failure of having a standard curriculum for teaching Islamic insurance as a profession in academic at national and international levels. Review of the literatures and curriculum was recommended.  相似文献

How do international investors react to announcements of cross-border mergers and acquisitions (CM&As) by emerging market multinational enterprises (EMNEs)? Using a unique and manually-constructed firm-level dataset, this paper examines the stock price reactions to CM&A announcements made over the period 1991–2010 by Chinese MNEs listed on the Hong Kong Stock Exchange and the wealth impacts of their corporate governance. Our empirical findings confirm a positive stock price reaction on average, and suggest that international investors react positively to the presence of large shareholders, but negatively to the presence of institutional shareholders. There is a negative impact if the largest shareholder is either the State or the corporate founder. We suggest that this is because the international investors perceive potential principal–principal conflicts in such ownership/control constellations and discount equity prices accordingly. We also find that Board size and independence have positive effects on the price reaction, but that large supervisory boards engender negative reactions.  相似文献

“平等”概念进入教育领域后,为我们解决了一些困扰已久的师生关系问题。但这种看似民主的师生平等观点,是否也夹杂着整个社会的权威退化值得探讨。在权威普遍丧失的今天,教育领域中万万不能丧失权威的概念,师生平等并不是师生关系最高标准,它甚至有弱化教师权威的倾向。如何建立起师生关系的最佳模式,如何帮助教师重塑在学生心目中应有的权威地位,阿伦特的权威观念也许可以作为一个指引。  相似文献

利用计量经济模型和通径分析法,该文对甘肃省工业行业的区际产业转移行业间溢出效应的影响因素进行分析。计量回归结果显示:人力资本、资本密集度对技术溢出具有显著的促进作用,技术差距对技术溢出具有显著的抑制作用,行业发展水平与技术溢出没有显著的相关关系。通径分析法与多元回归结论基本一致,但通径分析法比多元回归更加优越。分析结果表明,技术溢出效应的影响因素应该是承接地一系列因子指标的一个集合。  相似文献
