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

Leo van Grunsven  & Floor Smakman 《Singapore journal of tropical geography》2002,23(1):70-92

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.  相似文献   

RURAL PLACE ATTACHMENT IN HISPANO URBAN CENTERS*     

JEFFREY S. SMITH 《Geographical review》2002,92(3):432-451

ABSTRACT. Continued rural‐to‐urban migration has helped motivate cultural geographers, long suspected of having a rural bias, to include urban areas in their purview. Patterns of gender, class, ethnicity, and commercialization have proved to be fertile subjects for research, but the elastic links between rural and urban places are not yet well understood. Hispanos, despite intense feelings of loyalty to their rural villages, moved en masse to cities in the 1940s. By the 1950s a majority of Hispanos were living in regional urban centers of the upper Rio Grande country, where wages were higher and employment was secure. This Hispano experience is a crucible for examining how urbanites' attachment to rural places is manifested in various cultural expressions brought from country to city: painted murals, burial preferences, popular music, and irrigation ditches. Understanding threads of rural culture that have been incorporated into the urban fabric in turn leads to clearer comprehension of the emotional attachment that urbanites have for rural areas and a better appreciation of the complexity of the urban cultural environment.  相似文献   

Alpine medicinal plant trade and Himalayan mountain livelihood strategies   总被引：5，自引：0，他引：5  

Carsten Smith Olsen  Helle Overgaard Larsen 《The Geographical journal》2003,169(3):243-254

Commercial alpine medicinal plants are collected from the wild by local rural households throughout the Himalaya and sold in order to increase household incomes. Recent studies indicate that this annual trade amounts to thousands of tonnes of roots, rhizomes, tubers, leaves, etc., worth millions of US dollars. The main market is in India. Based on a national survey, including the most commonly traded species, and a village study this paper investigates the importance of the alpine medicinal plant trade at national and local levels in Nepal. The national survey included standardized open-ended interviews with 232 harvesters, 64 local traders, 66 central wholesalers, 47 regional wholesalers, and 16 production companies. The village survey is based on the daily records of household activities in 15 households in a one-year period. The annual Nepalese alpine and sub-alpine medicinal plant trade is conservatively estimated to vary from 480 to 2500 t with a total harvester value of US$0.8–3.3 million; the average harvester value is estimated at US$66.0 ± 99.0. The trade in 1997/98 amounted to 1600 t with a harvester value of US$2.3 million and an export value equivalent to 2.5% of total export from Nepal. Medicinal plant harvesting was found to constitute an integrated part of local livelihood strategies, contributing from 3 to 44% (average of 12%) of the annual household income. Importance at household level depended on land and animal holdings, and the availability of adult male labour. The validity and reliability of methods and analyses is evaluated, and issues of conservation and management of alpine medicinal plant species under the community forestry scheme are discussed.  相似文献

中国劳动力资源配置区域差异分析   总被引：3，自引：0，他引：3  

朱俊林 《地域研究与开发》2003,22(6):55-58

区域经济发展和经济结构调整的关键在于劳动力资源的合理配置。中国各省市区劳动力资源的产业和行业分布具有显著的地域差异，在空间分布上东、中、西部具有差异，西部地区的西南和西北地区也存在差别，这种规律反映了我国经济发展和产业结构高级化的区域差异。根据劳动力行业配置的区位熵排序结果，将各省市区分成4种类型：大都市型、沿海高工业化水平型、中等工业化水平型、中下等工业化水平型。这些类型具有自东向西有规律性的分布，与我国的经济发展格局和工业化水平的东西差异相应。  相似文献   

Digital effects in the spatial economy of film: towards a research agenda     

Andrew Currah 《Area》2003,35(1):64-73

A new assemblage of digital technologies, organized around compressed software formats and broadband Internet infrastructures, is reconfiguring the motion picture industry. In this paper, I review the impacts of digitization upon the spatial economy of film in the United States via a commodity chain framework. The discussion raises some important themes for conceptual debate in economic geography.  相似文献   

Crisis, coincidences and strategic market behaviour: the internationalization of Indonesian clothing brand-owners     

Markus Hassler 《Area》2003,35(3):241-250

Despite the fact that most Indonesian brand-owners continue to emphasize their marketing activities in the domestic market, several brand-owners have started to export clothing under their own label. This has been particularly the result of the economic crisis in the late 1990s, which affected companies serving the domestic market. Companies were trying to compensate for the loss of sales on the domestic market by redirecting their marketing activities to foreign countries. This export strategy has been driven largely by the sole aim to survive. However, in addition to these export activities, some companies have rather sophisticated, long-standing business relations to their distributors in overseas markets. This paper explores these export activities in the context of the global commodity chain framework.  相似文献
