Selected AbstractsMaterials Metabolism Analysis of China's Highway Traffic System (HTS) for Promoting Circular EconomyJOURNAL OF INDUSTRIAL ECOLOGY, Issue 4 2010Zongguo Wen Summary With the rapid growth of highway mileage and vehicles, the Chinese highway traffic system (HTS) has become one of the great resource consumers. This article attempts to evaluate the material metabolism of China's HTS during 2001,2005 using the approach of material flow analysis (MFA) and to explore possible measures to promote circular economy throughout HTS. We measured a set of indicators to illustrate the whole material metabolism of China's HTS. The results indicated that the direct material input (DMI) of China's HTS increased from 1181.26 million tonnes (Mt) in 2001 to 1,874.57 Mt in 2005, and about 80% of DMI was accumulated in the system as infrastructure and vehicles. The domestic processed output (DPO) increased by 59.0% from 2001 to 2005. Carbon dioxide and solid waste accounted for 80.5% and 10.4% of DPO, respectively. The increase of resource consumption and pollutant emissions kept pace with the growth of transportation turnover. All these suggest that China's HTS still followed an extensive linear developing pattern with large resource consumption and heavy pollution emissions during the study period, which brought great challenges to the resources and the environment. Therefore, it's high time for China to implement a circular economy throughout the HTS by instituting resource and energy savings, by reducing emissions in the field of infrastructure construction and maintenance, by reducing vehicles' energy and materials consumption, and by recycling waste materials. [source] Geography of Production Linkages in the Irish and Scottish Microcomputer Industry: The Role of LogisticsECONOMIC GEOGRAPHY, Issue 3 2005Chris van Egeraat Abstract: The economic crisis of the mid-1970s marked the transition from the traditional Fordist mode of industrial organization to one of time-based competition (TBC). It has been postulated that the rise of TBC will lead to an increase in local and regional production linkages. Part of the argument is that the associated search for logistical efficiency and the adoption of the just-in-time (JIT) principles will lead to closer buyer-supplier proximity. In this article, we test the relevance of this idea in a case study of the microcomputer hardware industry in Ireland and Scotland. Most of the data were collected during multiple interviews with subsidiaries of all global microcomputer assemblers with operations in one of the two countries. The study shows that rather than sourcing locally or regionally, the assemblers import the vast majority of their material inputs from regions outside Ireland and Britain, notably from the Far East, and that the inbound logistics pipelines of most components involve inventories, often hubbed in local warehouses. Such supply systems have been interpreted as pseudo-JIT, suboptimal inbound logistics systems that are organized on traditional Fordist principles. We argue that the logistics systems and the geography of the supply linkages should not be interpreted this way. Inbound inventories were tightly managed, leading to modest target buffer levels and high shipment frequencies. Even under JIT supply, the geographic configuration of production linkages and the details of logistics systems remain highly dependent on a range of contextual conditions and component characteristics. The findings of this study suggest that a strategy of building integrated vertical production clusters around subsidiaries of multinational enterprises is no longer suitable for Ireland and Scotland, at least not in the context of the microcomputer industry. [source] TNC Strategies and Variations in Intra-firm Trade: The Case of Foreign Manufacturing Affiliates in SwedenGEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 1 2000Inge Ivarsson The aim of this paper is to contribute to the understanding of the forms and determinants of intra-firm trade, i.e. international trade between different units under common TNC ownership, this being a major indication of ,deep economic integration' between developed countries in the 1990s. Theoretically, intra-firm trade can be explained by the existence of economies of common governance and are often found to be associated with R&D-intensive industries and economies of scale. In empirical studies, intra-firm trade is often found to consist of intermediate inputs goods, resulting in vertically integrated production chains. The study is based on detailed firm-level data from around 300 foreign majority-owned affiliates (MOFAs) in manufacturing, in Sweden in 1993. The results show that intra-firm sales by MOFAs in Sweden are as high as those found in studies of manufacturing affiliates of US TNCs. Almost all of MOFAs' intra-firm exports are finished products, while intra-firm imports consist of material inputs and finished products for resale. This suggests that these MOFAs are only marginal involved in vertically integrated production chains, especially in terms of exports. The results of a regression analysis complement earlier studies by showing that the level and composition of intra-firm trade is significantly affected by the international strategy applied by TNCs when operating foreign manufacturing affiliates. Intra-firm exports of finished products and material inputs are positively associated with efficiency-seeking FDI, e.g. affiliates engaged in rationalised production. Market-seeking FDI is associated with intra-firm imports of complementary finished products for resale. By contrast, resource-seeking and strategic asset-seeking FDI was negatively associated with intra-firm trade. [source] A firm level analysis of trade, technology and employment in South AfricaJOURNAL OF INTERNATIONAL DEVELOPMENT, Issue 1 2004Lawrence Edwards This paper uses two firm level surveys, the National Enterprise (NE) survey and the Greater Johannesburg Metropolitan Area (GJMA) survey, to explore the implications of globalization for employment in South Africa. These relationships are explored using cross-tabulations and estimated labour demand functions. The paper finds that rising import penetration negatively affected employment in large firms, but not small firms. Relatively large declines in employment also occurred within export firms, despite improvements in export competitiveness and export growth through trade liberalization. Finally, the study finds that skill-biased and trade-induced technological change, as reflected in increased use of computers, foreign investment and the importation of raw material inputs, have raised the skill intensity of production.
