实物量分析法是欧美一些发达国家常用的项目投资编制办法,在我国则是80年代末开始引入的。实物量分析法与传统估价方法相比具有与工程实际结合紧密,估算精度高的特点,应当大力推广,实物量分析法与传统方法各有所长,并不相互排斥,因此,在大力推广实物量分析法的同时,应不断对传统估价方法加以完善,使其适应形势,发挥更大的作用。 相似文献

量本利分析法一般用于利润预测和判断经营状况。量本利分析法的基本原理是利用成本习性,即根据成本和产量之间的关系,对利润进行匡算的一种科学方法。企业中的财务预算、成本控制都使用这种方法。采用这种方法虽然简便易行,但也存在许多局限性。本文就量本利分析法的局限性所存在的相关问题加以分析,并提出解决方法。 相似文献

The paper focuses on third generation wireless technologies and on alternative technologies for wireless local area networks. The authors present the evolutionary migration path from second to third generation systems. Technological, economic and behavioral factors related to decision-making towards the migration are proposed. As an example, the paper studies the case of the national incumbent operator of India. It analyzes qualitatively the migration problem from the perspective of the operator, the equipment manufacturer and the users. For the quantitative analysis, real options are used to value the investment decisions. The analysis suggests that the initial (sunk) investment cost, the average revenue per user, the growth of the subscriber base and the volatility of the markets are the key factors in the investment process. 相似文献

This paper analyzes the impact of WLAN technologies for incumbent MNOs based on an empirical cross-country study of the players in the public WLAN-hotspot market using the theory of disruptive innovation and theoretical extensions for the industry- and country-level. The main research question to be analyzed is whether and why PWLAN has shown a disruptive or sustaining impact trend for incumbent MNOs in the hotspot markets of Germany, the UK, and the USA in recent years. The results imply that incumbent MNOs and new entrants have taken advantage of the opportunity provided by PWLAN, but the market success of both types of players varies between the countries analyzed. Incumbent MNOs dominate in Germany but not in the UK and the USA. The reasons for these country-specific differences were further investigated, and the results suggest that the analysis of disruptive potential in telecommunications needs to include country- and firm-specific factors, which are, again, largely influenced by the local regulation. 相似文献

In January 1995, the Kobe earthquake devastated a major part of Kobe's distribution infrastructure. Apart from the expected complaints about lost sales, wholesalers reported some surprising comments after the reopening. Wholesalers stressed the advantages of newly designed distribution channels, especially the opportunity to end longstanding business relationships known as keiretsu. This study is concerned with the recent development of vertical collaboration in the Japanese distribution channel. Multiple regression analysis revealed that the supplier's service to wholesaler, the supplier's offerings to the wholesaler, and buyer's service to the wholesaler did contribute to the enhancement of the performance of the wholesaler. The three factors explained 16% of the wholesaler's performance. The regression analysis also showed that the wholesaler's intra-logistics activities contributed to the improvement of the performance of the wholesaler and explained 5% of its performance. 相似文献

This special section aims to investigate the interaction of global and local forces in shaping agrifood governance. It starts from the recognition that a multitude of actors and norms shape today’s agrifood system. The resulting opaqueness of the systems makes it extremely difficult to understand and explain processes and outcomes of agrifood governance. Given the sustainability challenges facing the agrifood system, improvements in our understanding of what the interaction of global and local actors and norms means on the ground are urgently needed, however. The section, therefore, analyses agrifood governance in India across a selected group of cases. It does so by employing a systematic framework emphasizing the material and ideational dimensions of power and their interaction. The section has chosen India as the setting in which to analyze this interaction due to the crucial role the food demand and supply of this rising power plays in today’s agrifood system. This article provides the special sections’ analytical framework, which uses the interplay of material and ideational dimensions of power as a focal lens. In addition, the article applies this framework to an empirical study of the political conflict around GMO foods in India, specifically the case of ‘Golden Rice’. 相似文献

This paper explores business-to-business (B2B) marketing on the Internet, and how the confluence of the two may transform the B2B landscape. Specifically, it discusses the notion of linkage value to demonstrate why the B2B phenomenon on the Internet is so significant. It then considers the mechanisms and enablers that have made the Web such an important B2B marketing channel. It also explores how the Web can reduce transaction costs, thereby facilitating more efficient exchanges and markets. The concepts of links and nodes are then introduced and the processes of disintermediation, reintermediation, disaggregation and reaggregation are explored. Finally, Web B2B configurations are considered by way of a model that describes four archetypal configurations, and the factors that are antecedent to these modes and how the Web may influence them. 相似文献
