E-commerce is growing to represent an increasing share of overall sale avenue, and online shopping is expected to continue growing for foreseeable future. As such, it is vital to identify the performance of shopping online and investigate the effects that shopping online has on e-commerce.The methods used in this study are consulting some authentic materials and looking into some cases in point. It is found that shopping online has so many disadvantages, such as credit crisis, the insecurity of e-bank, express problem, a series of relevant law problems, limited payment options and so on.Because of these limitations, shopping online has interfered with e-commerce. Overall, shopping online is more or less a bar to e-commerce.展开更多

In the past years, cloud computing has become from a theoretical concept into the real applications in different industries such as telecommunication and healthcare. Inevitably, its influences on different industries have also attracted much attention. Based on the literature review, this paper discussed how the traditional E-commerce businesses and industry were influenced by cloud computing in technical architecture, service modes and the industrial chain. Besides, it analyzed the driving-forces which led to the changes of E-commerce in cloud era. Finally, it concluded that only when the E-commerce enterprises involved cloud computing in the business strategy and established the core competencies, could they realize the sustainable development in the cloud era.展开更多

In most of the existing recommender systems, only the purchase information is utilized data and the navigational and behavioral data are seldom concerned. In this paper, we design a novel recommender system for comprehensive online shopping sites. In the proposed recommender system, the navigational and behavioral data, such as access, click, read, and purchase information of a customer, are utilized to calculate the preference degree to each item; then items with larger preference degrees are recommended to the customer. The proposed method has several innovations and two of them are more remarkable: one is that nonexpendable items are distinguished from expendable ones and handled by a different way; another is that the interest shifting of customers are considered. Lastly, we structure an example to show the operation procedure and the performance of the proposed recommender system. The results show that the proposed recommender method with considering interest shifting is superior to Kim et al(2011) method and the method without considering interest shifting.展开更多
