Developing E-commerce may reduce trading cost, enhance trading efficiency, allocate social resources and push forward reform and innovation in the management of traditional enterprises. E-commerce facing entry into WTO of China, business administration and computer applications has fallen behind, E-commerce infrastructure has not been built well, and network society has not formed a definite scale. On the basis of analysis on the environment of the development of E-commerce, this paper puts forward some appropriate countermeasures. They are to lay down China E-commerce strategy, carry out knowledge management, establish E-commerce strategy alliance, reconstruct digital core products, reorganize enterprise resources, practice administration technology such as SCM, CRM and ERP, and strengthen E-commerce infrastructure for a better environment of E-commerce development.展开更多

However, the ranking result always has a big deviation with actual rank for the existence of unknown web traffic, which cannot be identified accurately under current techniques. In this paper, we introduce a novel method to approximate the actual rank. This method associates unknown web traffic with websites according to statistical probabilities. Then, we construct a probabilistic top-k query model to rank websites. We conduct several experiments by using real HTTP traffic traces collected from a commercial ISP covering an entire city in northern China. Experimental results show that the proposed techniques can reduce the deviation existing between the ground truth and the ranking results vastly. In addition, we find that the websites providing video service have higher ratio of unknown IP as well as higher ratio of unknown traffic than the websites providing text web page service. Specifically, we find that the top-3 video websites have more than 90% of unknown web traffic. All these findings are helpful for ISPs understanding network status and deploying Content Distributed Network(CDN).展开更多

We take a case study approach to explore borderless development at business, managerial, and operational levels and to study four facilitators of borderless development： information technology, the virtual world, virtual operations, and concentration on core business. We conclude that firms may achieve global dominance in their area of core competency through borderless development.展开更多

Web usage mining is the process of applying data mining to the discovery of user behavior patterns based on Web log data, well suited to this problem. As an important field of Web usage mining, mining user navigation patterns is the fundamental approach for generating recommendations. In this paper, we propose an ant colony approach for navigation patterns. We use the ant theory as a metaphor to guide user＇s choice in the Web site.展开更多

With the development of financial market after China＇s entry into WTO, the investment banks confront with immensely international competition. Meanwhile, Chinese investment banks are facing with problems such as elementary business structure, small capitalization and faultiness of governance, which lead to their less competitive power. This article conducts research from the perspective of path optimization of business structure of investment banks. Through economic analysis of path optimization of business structure, we conclude path optimization of business structure of domestic investment banks will lay a solid foundation for enhancing their competitive power. Whereafter this article constructs optimized path for business structure of Chinese investment banks and analyzes the influence factors of the optimized path. At last, this article advises on how to enhance the business structure of Chinese investment banks.展开更多
