Exploring determinants of adoption intentions towards Enterprise 2.0 applications: an empirical study

Enterprise 2.0 is identified as one of the most promising technological innovations in the business domain, with immense potential for enriching communication, enabling collaboration and facilitating learning. Although organisations are increasingly implementing Enterprise 2.0 as a useful means of knowledge sharing and collaboration, no empirical research has been performed to identify individuals’ motivations to participate in Enterprise 2.0 activities. The high practical relevance and dearth of research indicate the importance of the present study. This study aims to apply the Unified Theory of Acceptance and Use of Technology to propose a research model that incorporates context-specific variables as enhancing constructs to predict individuals’ adoption intentions towards Enterprise 2.0 applications. We also categorise Enterprise 2.0 users into silent and social users and conduct a comparative analysis to examine whether differences exist in factors predicting users’ adoption intentions towards Enterprise 2.0 applications. To test the model, structural equation modelling is employed to analyse data collected from respondents working in seven Chinese companies conducting trial operations of an Enterprise 2.0 platform. The findings of this research provide managers with effective methods to promote individuals’ participation in Enterprise 2.0 activities. This research also provides a theoretical foundation for academics and practical implications for the development of Enterprise 2.0.

For this purpose, a research model and hypotheses are developed based on the relevant literature reviews. Data have been collected from 248 users who have used internet banking and the research hypotheses were tested by covariance structural model analysis. The results of this empirical study are summarized as follows. First, security, confirmation, and perceived ease of use have positive influence upon user`s perceived usefulness. Second, security, economy efficiency, and confirmation have positive influence upon user`s satisfaction. Third, loyalty incentives have positive influence upon continuance intention.

Exploring the Role of Perceived Interactivity in Establishing Behavioral Intention in Micro-blog Environments

The growing prevalence of the Web2.0 is promoting micro-blog as one of the most promising innovations in the past few years. This study develops a model aims at investigating the effects of perceived interactivity in establishing behavioral intention within micro-blog environments. We also categorized micro-blog users into extroverts and introverts to examine whether differences exist in the role of perceived interactivity in predicting behavioral intention. The results suggest that behavioral intention is determined by perceived interactivity, performance expectancy, sense of belonging, and hedonic expectancy which together provide a strong explanation. The results of this study provide directions for service providers to achieve higher levels of micro-blog usage by developing multi-faceted strategies.
