Technology acceptance in public sector: an empirical study of a knowledge management system in Kaohsiung City Government

This research investigates the applicability of the extended Technology Acceptance Model (TAM) to user acceptance of a Knowledge Management System (KMS) in the public sector. Significant positive relationships between perceived usefulness, ease of use, behavioural intention, and behaviour were consistent with previous research results. The observed mediating role of perceived usefulness in the relationship between ease of use and behavioural usage was also in consonance with earlier findings of similar research in the private sector. Cognitive instrumental processes, including job relevance, output quality, result demonstrability, and perceived ease of use significantly affect perceived usefulness. Policy implications and recommendations for promoting KMSs in the public sector are further discussed.
