Measurement of the Knowledge-Sharing Efficacy of Web2.0 Site Constructed on the Basis of Knowledge-based Systems by Applying the Model of UTAUT: Evidence of the early adopters
Many websites have gradually constructed the sharing mechanism of web2.0 through knowledge-based Systems. We use the Unified Theory of Acceptance and Use of Technology and the theory of knowledge-sharing self-efficacy to show that the performance expectancy, effort expectancy and social influence have significant impact on the knowledge-sharing self-efficacy of an individual and that facilitating conditions have no conspicuous impact. The contributions of the research include providing a reference from which the managers of the Web2.O sites constructed on the basis of knowledge-based systems cam make decisions for development, and demonstrating the feasibility of applying concepts from the field off information activity in social sciences to the field of knowledge-based systems to study problems from different viewpoints and form new research directions.
