Our results are based on our 10-year investigation of IT adoption in Chinese companies and industry-specific patterns of...
Article
The application of e-ordering systems has brought significant changes to the drug distribution industry in China, but the effects of these changes have remained unclear. Adopting a practice perspective and based on longitudinal data collection using multiple methods, we reveal that the Chinese drug distribution practice has passed through the follo...
Article
Corporate blogs are expected to facilitate communication, knowledge sharing, and collaborative innovation within organizations. However, empirical evidence has yet to be found illustrating whether and how such applications have affected job performance. Drawing upon social network theory, we postulate a conceptual model suggesting that employees on...
Article
Content generated on intra-organizational blogging platforms may help managers understand the emerging ideas, issues, and opportunities of their companies, whereas the difficulty is how to go beyond the overload of information and obtain an overall view. This paper proposes a system framework for extracting representative information from intra-org...
Article
Voting mechanisms are widely adopted for evaluating the quality and credibility of user-generated content, such as online product reviews. For the reviews that do not receive sufficient votes, techniques and models are developed to automatically assess their helpfulness levels. Existing methods serving this purpose are mostly centered on feature an...

In sponsored search advertising, keywords serve as an essential bridge linking advertisers, search users and search engines. Advertisers have to deal with a series of keyword decisions throughout the entire lifecycle of search advertising campaigns. This paper proposes a multi-level and closed-form computational framework for keyword optimization (...
Conference Paper
Live streaming selling is a transformative e-commerce channel that features real-time interaction between a streamer and a mass audience. However, streamers' service capacities cannot fulfill viewers' needs for social interaction, resulting in a loss of viewer engagement and financial gains. Accordingly, we examine whether the implementation of an...

E-commerce platforms generally provide various functions that can be adopted as signals for online sellers to convey implicit information to customers to promote sales. In this article, based on signaling theory and the stereotype content model, we categorize e-commerce signals into two types: signals of competence and signals of warmth. Signals of...
Article
Complements and substitutes are two typical product relationships that deserve consideration in online product recommendation. One of the key objectives of recommender systems is to promote cross-selling, which heavily relies on recommending the appropriate type of products in specific scenarios. Research on consumer behavior has shown that consume...
Chapter
Recent years have witnessed the great passion of shoppers to purchase products at promotion, resulting in “smarter” consumers with growing price sensitivity towards promotion. In order to provide such price sensitive consumers with personalized promotion recommendations, it is important to take account of the temporal uncertainty of consumer prefer...

Previous research has found that social networking applications such as microblogs can develop gratification and addiction among users. Although it is generally believed that gratification reflects the gains through use and that addiction is caused by excessive use of the technology, limited research has been done to empirically verify the relation...
Conference Paper
Existing research on recommender systems has mostly focused on developing algorithms to predict the degrees to which a consumer may like a product. Recommended products are usually presented based on their predicted ratings in descending order. Considering the cognitive process of online consumers, when users evaluate the recommended products in se...

Our study is aimed at identifying the characteristics of emerging mobile technologies and the typical attributes of tasks...
Article
To envisage possible future enterprise systems, we describe four scenarios that all respond to the increasing need for better supply chain-wide coordination of resource allocation decisions. We use two drivers to derive these scenarios; namely “normal form of providing corporate computing resources” and “stance of regulators towards explicit forms...

Chapter
One interesting aspect of the emerging industry-wide information infrastructure not yet explicitly addressed is that two systems exist in parallel to one another, the government-imposed centralized e-bidding platform and the company-driven B2B platforms. While the government-imposed platform experienced, to some extent, a reduction in importance it...
Chapter
There are three possible limitations to our study and its results. The first two concern the domain that we studied. It might be the case that our findings are specific to both the Chinese context and the pharmaceutical distribution industry. Specifically the first limitation related to China as a research site may seem to suggest a high degree of...
Chapter
As described above, we have used two approaches to analyse our data, which we labelled a life cycle and a teleological approach. The life cycle approach is based on our previously published multi-level framework for studying the emergence of B2B e-commerce systems and the teleological approach is based on a bottom-up coding process.
Chapter
Partly based on our findings, but also extrapolating our own ideas, we suggest that the 2020 Enterprise has the following three characteristics.

The study, which commenced in 2004 and is still ongoing, is supported by a research environment that we call a Learning Community (LC). This is a novel concept and research tool that comprises an industry group which engages in collective action to create a novel information infrastructure. ‘Industry group’ is defined in terms of a value system whi...
Chapter
In the early 2000s, amid the difficulties facing the overall medical and healthcare industry, the chaotic situation in the pharmaceutical distribution chain triggered the government to centralize drug procurement on the national level, based on electronic biddings systems. To put this policy in perspective, China’s pharmaceutical distribution syste...
