Competitive Adjustment and Advancement in Global Commodity Chains II: The Case of the Singapore Garment Industry

This is the second part of a contribution to the debate on the possibilities of leveraging economic globalisation — through incorporation in international production networks and global commodity chains (GCCs) — as a strategy for developing countries to industrialise and advance their position in the world economy. In the first part, we analysed the experience of the East Asian apparel industry and addressed the issues of sustaining positions, upgrading to more rewarding roles, and advancing to less dependent positions within production networks and GCCs. We developed an analytical framework at both the firm and industry levels, and subsequently identified alternative firm- and industry-level strategies and trajectories. The present paper deals with these issues in the context of the Singapore apparel industry. Based on extensive empirical research, we demonstrate that although the East Asian experience of upgrading and repositioning within the GCC is to some extent emulated in the case of the Singapore apparel industry, the outcomes have been less favourable in terms of the depth, extent and strength of these trajectories. The differing outcomes can be explained in terms of different (systemic) conditions in the Singapore business environment, including the agency of local players, the geography of sourcing networks, and the role of the state and prevailing business attitudes. Our conclusions merit continued attention in both research and policy circles on the development of capabilities at the firm level, and the role of local business and institutional environments in local industry development processes under globalisation.     

Issues of Globalization and Reflexivity in the Japanese Tourism Production System: The Case of Whistler,British Columbia

This article examines contemporary Japanese overseas tourism from a supplier‐side perspective using the concept of production systems. We first outline characteristics of the evolving structure of Japanese overseas tourism, with an emphasis on the global spread of Japanese travel companies. This provides a frame for presenting an empirical account of the transactional relationships in the Japanese package tour production system in Whistler, British Columbia, where Japanese tour operators play a pivotal role. We conclude that the recent expansion of Japanese travel companies is fostering the functional integration of the global tourism production system and exhibits increasing reflexivity.     

Markets, ethnicity and environment in a vulnerable landscape: the case of small-scale vegetable production on the Jos Plateau, Nigeria, 1991–2001

This paper explores changing socio-environmental interactions in the vegetable producing areas of the Jos Plateau over the decade 1991–2001. It considers the pressures of market forces and ethnic competition and the tensions which arise as interactions between the two are played out in a fragile physical, social and institutional environment. The region has seen a remarkable expansion in irrigated vegetable production, as dry season surveys in 1991 and 2001 attest. Local farmers appear extremely positive in their perceptions of change, pointing not only to expanded production, but also to other improvements, like growing percentages of children in school and improved transport. But behind this rosy view of change there are tensions and a series of unresolved questions which may soon have to be addressed. We examine the changing nature of socio-environmental interactions over the decade and ask whether and how current levels of production can be sustained in the context of a currently largely unregulated production system and growing competition for land. Given the important role of the Plateau as a source of temperate fruit and vegetables in West Africa, these questions have significance far beyond the Plateau region itself.     

国外漂白粘土和澄清粘土的产销现状综述

漂白粘土和澄清粘土应具有较大的表面积、较高的吸附性能及褪色能力,多由膨润土经活化(酸化)处理后制成。当前,德国、美国在世界漂白土生产中占据重要地位。漂白粘土和澄清粘土世界市场销量约86万t/a,其中70％～80％用于食用油和油脂工业。漂白粘土的发展受食用油工业发展的影响最大,亚洲还有较大的发展空间。澄清粘土多用作葡萄酒、果汁等的澄清剂,也有一定的发展前景。漂白土再利用的途径,仍在探索中。     

煤层气富集高产的主控因素

对煤岩的生储气能力、煤储层渗透率、煤层气保存条件等影响煤层气高产富集的主控因素进行了分析。煤岩组分和煤变质程度是影响煤层生储气能力的主控因素。煤层的储气能力与温度、压力、灰分及水分含量等亦有关。煤层的渗透率取决于煤层本身的裂隙系统,而裂隙的发育程度又与煤变质程度及构造活动的强弱相关。煤层气的保存则取决于顶底板的封盖能力、构造活动、水动力环境等条件。煤层气成藏条件是煤层气基础地质研究中的核心问题,应加强研究。

末次盛冰期以来全球湿润状况的地质证据──全球古湖泊数据库及其湖水位变化的大尺度时空分析

介绍了正在建设中的全球湖泊数据库的情况，以及该数据库的水位资料所反映的晚更新世末期以来全球湿润状况的变化。通过大尺度湖水位变化的时空分析，结果显示当今湖泊水位状态较历史时期而言，位于低纬干旱或半干旱地区的湖泊水位较低，而中纬及高纬湿润地区的湖泊水位较高。自末次冰盛期以来，北美大陆中南部地区湖泊水位自高至低，反映出该地区气候条件由湿变干，至早、中全新世达最干旱。而在非洲及南亚季风地区，冷期偏干，暖期偏湿。特别是在早、中全新世的温暖时期，为历史上最湿润时期。北半球中纬度地带的气候干湿变化与北半球冰盖的存在及其消融导致的西风带的南北摆动有关；而北半球季风区在早、中全新世出现的高潮面与北半球夏季辐射的增加有密切联系。
