The principal aim of this paper is to evaluate the impact of the future European high-speed train network on accessibility, by reducing time distance between places and modifying their relative location. We compare the current situation with that foreseen for the year 2010, according to the Outline Plan of the European High-Speed Train Network, in order to analyse which areas will most benefit from construction and improvement of the infrastructure. It is hypothesized that the high-speed train will certainly bring the peripheral regions closer to the central ones, but will also increase imbalances between the main cities and their hinterlands. A weighted average distance indicator is applied for this purpose. This measure identifies the spatial distribution of accessibility in the area of study, emphasizing the infrastructure effects, and locates accessibility changes at the European level. A Geographic Information System (GIS) has been used to carry out this study.  相似文献

This study investigates how participating in strategic alliances with rivals affects the relative competitive positions of the partner firms. The paper builds on studies that show significant differences in the outcomes of scale and link alliances. The study argues that the more asymmetric outcomes of link alliances translate into greater changes in the relative market shares of the partner firms, due to unbalanced opportunities for inter‐partner learning and learning by doing. We find support for this argument by examining 135 alliances among competing firms in the global automobile industry, from 1966 to 1995. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

The theory articulated in this paper suggests that the desire to reduce demand and competitive uncertainty are two separate, important motives for alliance formation. Taking this as a starting point, we predict the configuration of horizontal alliances that we might expect to observe within an industry when firms experience these uncertainties to different degrees. An empirical test of this theory using data from the global auto industry yields results consistent with the view (1) that alliances are a device for reducing both the uncertainties that arise from unpredictable demand conditions and those that arise from competitive interdependence, and (2) that variation of demand uncertainty and competitive uncertainty across firms explains differentials in both the intensity and structure of their horizontal alliance activity.  相似文献

房地产业中政府与房地产开发商之间的关系既是行业主体关注的重点,也是国家如何加快房地产业发展步伐的核心问题。近年来,国内外专家研究房地产行业开发商与政府的行为的很多,但大多仅停留在对现象的描述,不够全面。本文以博弈论及信息经济学理论为依据,分析了房地产业开发商与政府的利益博弈,建立了存在政府监管情况下开发商行为选择的“监管博弈”模型,并且求解出纳什均衡解。在此基础上,给出了应对房地产市场各种情况的治理对策,以实现加快城市建设步伐、保证社会经济的协调、健康和长远发展。  相似文献

Vertical intra-industry trade and foreign direct investment in East Asia   总被引:4,自引:0,他引:4  
As economic integration in East Asia progresses, trade patterns within the region are displaying an ever-greater complexity: Though inter-industry trade still accounts for the majority, its share in overall trade is declining. Instead, intra-industry trade (IIT), which can be further divided into horizontal IIT (HIIT) and vertical IIT (VIIT), is growing in importance.In this paper, we set out to measure and examine vertical intra-industry trade patterns in the East Asian region and compare these with the results of previous studies focusing on the EU, to which such analyses so far have been confined. Based on the supposition that VIIT is closely related to offshore production by multinational enterprises, we then develop a model to capture the main determinants of VIIT that explicitly includes the role of FDI. The model is tested empirically using data from the electrical machinery industry. The findings support our hypothesis, showing that FDI plays a significant role in the rapid increase in VIIT in East Asia seen in recent years. J. Japanese Int.

近年来,我国零售商供应商矛盾突出,引起了各方关注。商务部等五部委发布的《零售商供应商公平交易管理办法》,是近年来专门调整零供关系的政府部门规章,在稳定流通秩序方面发挥了一定的作用,但对此也有一些不同观点。为完善零供(买卖)关系的法律规范体系,推进和谐商业环境及商事法治建设,本文对调整零供关系的法律属性,少数零售企业恶意占压、骗取供应商贷款的综合治理,风险预誓机制等相关问题提出了自己的一些见解。  相似文献
