Migrants and International Economic Linkages: A Meta-Overview

Abstract

The migration issue is a much debated subject in many developed countries. This study provides a review of the relationship between migrants and their international economic linkages. It then focuses on foreign direct investment (FDI), for both inward and outward FDI. This study aims to offer a synthesis by means of a meta-analysis of various studies, in order to test the robustness of the relationship between migration and FDI. Our results confirm that immigration has a positive impact on FDI investment in both directions (inward and outward), and that these impacts are higher when migrants are highly educated and skilled.

RÉSUMÉ Le problème de la migration est un sujet qui suscite un intérêt considérable dans un grand nombre de pays évolués. Cette étude passe en revue les rapports entre les migrants et leurs liens économiques internationaux. Elle se penche en suite sur les investissements étrangers directs (IED), tant pour les IED étrangers que pour les investissements à l’étranger. L’étude s'efforce de présenter une synthèse par le biais de méta-analyses de différentes études, dans le but de tester la solidité des rapports entre migration et IED. Nos résultats confirment que la migration a eu un effet positif sur les investissements IED dans les deux sens (de l’étranger et à l’étranger, et qu'elle a un impact majeur lorsque les migrants sont des personnes haute ment qualifiées et spécialisées.

RESUMEN La inmigración es un tema muy debatido en muchos países desarrollados. Este estudio proporciona una reseña de la relación entre los inmigrantes y sus enlaces económicos internacionales. Después se enfoca en la Inversión Extranjera Directa (IED), tanto de entrada como de salida. Este estudio tiene como objetivo ofrecer una síntesis mediante un metanáli sis de estudios varios para evaluar la solidez de la relación entre inmigración y la IED. Nuestros resultados confirman que la inmigración tiene un impacto positivo sobre la IED en ambas direcciones (entrada y salida), y que estos impactos son mayores cuando los inmigrantes tiene un alto nivel de educación y cualificación.

     

基于计算思维培养的计算机程序设计课程探索

计算思维的培养是21世纪大学教育领域的重要课题之一,本文主要讨论了在计算机程序设计课程中,针对非计算机专业的学生,如何调整教学理念和教学方式,从传统的技能培养提升到思维培养。首先对计算机程序设计课程进行了重定位,将传统知识模块和计算思维的特征进行有机结合,并且提出在教学各个环节q-,以“重思维、轻规则”为总的原则,对计算机基础教学进行全方位改革。     

Manufacturing Sector Growth: A Case Study of Singapore

Abstract

This paper attempts to highlight some of the challenges faced by the Singaporean economy in general and the manufacturing sector in particular. Statistical analysis is used to demonstrate the role of human capital and foreign investment on manufacturing output for the period 1980–2004. The paper shows that a long-run relationship exists among the real manufacturing output per-unit of employment, real foreign investment per-unit of employment and real human capital per-unit of employment. The paper also provides time series forecasts for the growth rates of real output, productivity and investment in Singaporean manufacturing sector.     

苏联解体前的白俄罗斯语言政策研究

语言政策的概念是多种多样的,但是不管其如何界定,都离不开特定国家和特定历史背景的存在基础。白俄罗斯的民族多样性和历史曲折性决定了其语言政策发展史的多样性。选取苏联解体前的白俄罗斯语言政策为研究对象,探索其语言政策发展的现实规律,有助于更加生动全面地体现白俄罗斯语的发展历程,对预测白俄罗斯语未来数年的发展趋势有着不可小觑的参考价值。     

Parent country nationals or local nationals for executive positions in foreign affiliates: An empirical study of Japanese affiliates in Korea

This study examines how the host country experience of Japanese multinational corporations (MNCs) affects their staffing policies for executive manager positions at foreign affiliates. Hypotheses on executive staffing policies for foreign affiliates are tested using survey data collected from 103 Japanese affiliates in Korea. Findings show that the level of global integration and the degree of centralization of decision-making positively affect an assignment of parent country nationals as executive managers of foreign affiliates. We further find that foreign affiliates’ experience in a host country moderates the effects of both global integration and centralization on staffing decisions for the affiliates.

Corruption and market attractiveness influences on different types of FDI

Previous studies have proposed that a compensatory model predicts the level of foreign direct investment (FDI) in a country; FDI levels are a result of ‘trade‐offs’ between the positive effect of market attractiveness and the negative influence of corruption. In contrast, we hypothesize and find that the compensatory relationship only holds for market‐seeking investment; for resource‐seeking FDI the model appears to be noncompensatory. Greater market attractiveness mitigates the negative impact of corruption on market‐seeking investment, but the ability of market attractiveness to mitigate the negative impact of corruption on resource‐seeking FDI quickly disappears as corruption levels increase. Implications and future research directions are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

FDI的利润汇出、出口创汇能力对我国国际收支的影响及趋势分析

本文运用1985-2006年的相关数据,通过区分和考虑不同类型外国直接投资对国际收支的影响渠道,分析了外国直接投资的利润汇出和出口创汇能力对我国国际收支特别是经常账户差额的影响。结果表明,外国直接投资是形成我国当前双顺差的主要因素。但是未来这种趋势将会发生变化。本文以2006年为基期进行预测,未来10年内,外国直接投资的出口创汇能力将由于外国直接投资从出口导向型更多地转向市场寻求型而下降,而利润汇出趋势将增强。因而,应加强对外国直接投资的动态监管,减少外国直接投资对我国国际收支的负面影响,避免可能由外国直接投资引起的经常账户危机。
