生产性服务业支撑制造业价值链升级的实证研究

在后危机时代,制造业应通过转型升级培育持续竞争力。制造业转型升级的重要内容之一是价值链升级。本文通过研究发现,生产性服务业与制造业价值链升级间的相关程度明显。在此基础上,以中国为样本,通过实证分析发现,当前对支撑中国制造业价值链升级贡献较大的生产性服务业是交通运输、仓储及邮政业和批发零售业这些传统服务行业,从而进一步指出,信息传输计算机服务业、金融业和科学研究技术服务业等现代服务业,应是将来发挥支撑制造业价值链升级作用的重点行业。     

The Revival of Chinese Costume Culture——Contrast Between Chinese and American Costume

Costume culture is an important symbol of a nation, which reflects directly the developing condition of a nation in a particular period.The Chinese nation boasts 5000 years of history as one of the four ancient civilizations in the world, while the United States is a relatively newly born na-tion.Since China's reform and opening, the Chinese realized their great disparity with the western world. This paper demonstrates the contrast between Chinese and American costume culture, and it makes the conclusion that the Chinese nation should rejuvenate its costume culture in the new period.

视觉表象能力与汉字书写能力关系的研究

文章旨在探究视觉表象能力与汉字书写能力两者之间的关系。以某大学的45名学生为被试,使用视觉表象能力测验和自编的汉字书写材料分别测量被试的视觉表象能力和汉字书写能力,并将被试的书写结果交予汉字专家进行评分。实验结果表明:(1)视觉表象测验的总正确率与汉字书写不同维度(笔画、笔顺、流畅度、整体感)的得分均有显著性相关;(2)视觉表象子测验(表象保持、表象分辨、表象旋转)的正确率和汉字书写的不同维度(笔画、笔顺、流畅度、整体感、篇章布局)的得分分别有着不同程度的相关且相关性显著。     

An exploratory review of the relationship between enterprise training and technology upgrading: evidence from South African manufacturing firms

The study examines the extent to which disaggregated training variables are related to technological upgrading, in the context of a middle-income developing country trying to manage its integration into the global economy. For a developing country, successful integration into the global economy requires that local manufacturing firms are able to competitively restructure, as a precondition for survival and long-term growth. Consequently, skills and technological upgrading are crucial in raising the international competitive advantage of local firms. Enterprise-provided training is one means that can be used by local firms to continuously upgrade their knowledge bases, increase their international competitiveness, and enhance employment growth over time. This paper uses South Africa as a case study, to demonstrate how economic reform measures can expose skills deficiencies in the manufacturing sector and lead to an increase in capital intensity of the sector. Exposure of skills deficiencies, in turn, raises the importance of skill-upgrading through schooling and training of existing workforce. Despite a couple of studies on the evolution of the labour market in South Africa, no previous research has explicitly examined the relationship between technological upgrading and disaggregated training/learning variables at the firm level. This paper aims to fill that gap by focusing on disaggregated enterprise-based training efforts. The study uses the Human Capital theoretical framework to answer the main research question: Which disaggregated learning variables (i.e., on-the-job or off-the-job training offered to different occupational groups) are significantly associated with technological upgrading? The study raises possible issues of heterogeneity in returns to training offered to different occupational groups in the context of technological-upgrading. On the other hand, technological upgrading may not necessarily always disadvantage all unskilled workers. Possible policy implications of research findings are outlined.     

Type A behaviour at work – an empirical study of Taiwanese managers and entrepreneurs

Bortner's Type A Behaviour Questionnaires were used to explore the work behaviour of Chinese managers and entrepreneurs in Taiwan and to investigate how that behaviour was influenced by occupation, age and gender. One hundred and seventeen subjects participated in the study, of which 45 were also interviewed. The mean score on the questionnaire was 74.68, the median (74) and the mode (76) within a scoring range of 0–140. Eighty-four subjects registered scores of 80 or less (Type B behaviour) and 33 came within the mid-range of 81–120. None of the subjects registered scores of 121–40 (Type A behaviour). The highest score of 113 was registered by a female bank vice-president and the lowest (47) by a male manager working in a charitable organization and about to retire. The results are discussed within the context of Chinese cultural traditional and parenting practices, the unique characteristics of Taiwan's recent history and the subjects' career experience.     

Informal Sector and Manufacturing Location: In Search of the Missing Links

Abstract

Although the informal sector is very large and unevenly distributed within developing countries, its relative size and location have not been investigated from the perspective of location models. This paper builds a modified Core–Periphery model where formal and informal firms compete in consumer markets. The model suggests that in a peripheral region, where informal goods constitute a competitive alternative to formal goods, a larger critical mass of workers is needed for the formal sector to become profitable. Informal sector competitiveness, however, also increases formal firms' sensitivity to home market effects. Thus, indirectly, a competitive informal sector can foster formal manufacturing agglomeration.

RÉSUMÉ Bien que le secteur informel soit très étendu et distribué de façon irrégulière dans les pays en voie de développement, son envergure et sa distribution relatives n'ont fait l'objet d'aucune étude sur le plan de modèles de localisation. La présente communication crée un modèle « centre–périphérie » modifié, dans lequel des entreprises officielles et non officielles rivalisent sur des marchés de consommation. D'après ce modèle, dans une zone périphérique où les produits informels constituent une alternative à des produits officiels, une masse critique de travailleurs plus importante est nécessaire afin que le secteur officiel devienne rentable. Toutefois, la compétitivité du secteur informel accro??t également la sensibilité des entreprises officielles à des effets sur le marché interne. En conséquence, un secteur informel compétitif peut, indirectement, encourager une agglomération de fabrication officielle.

EXTRACTO Aunque el sector informal es muy amplio y está irregularmente distribuido dentro de los países en desarrollo, su tamaño relativo y localización no se han investigado desde la perspectiva de modelos de localización. Este estudio construye un modelo modificado de centro–periferia donde empresas formales e informales compiten en mercados de consumo. El modelo sugiere que, en una región periférica donde las mercancías informales constituyen una alternativa competitiva a las mercancías formales, el sector formal necesita una mayor masa crítica de trabajadores para ser rentable. No obstante, la competitividad del sector informal también aumenta la sensibilidad de las empresas formales a los efectos del mercado doméstico. Por lo tanto, indirectamente, un sector informal competitivo puede fomentar la aglomeración de la industria manufacturera formal.

The Financial Deepening-Productivity Nexus in China: 1987–2001

The financial intermediation-growth nexus is a widely studied topic in the literature of development economics. Deepening financial intermediation may promote economic growth by mobilizing more investments, and lifting returns to financial resources, which raises productivity. Relying on provincial panel data from China, this paper attempts to examine if regional productivity growth is accounted for by the deepening process of financial development. Towards this end, an appropriate measurement of financial depth is constructed and then included as a determinant of productivity growth. It finds that a significant and positive nexus exists between financial deepening and productivity growth. Given the divergent pattern of financial deepening between coastal and inland provinces, this finding also helps explain the rising regional disparity in China.
