| Summary: | 碩士 === 國立東華大學 === 高階經營管理碩士在職專班 === 98 === Knowledge can be considered as a key organizational resource or as an asset embedded with context, and must be managed effectively. It is becoming accepted that knowledge management is required for modern organizations seeking to stay competitive in an increasingly dynamic and competitive world. The purpose of knowledge management systems is to support the flow of knowledge and intelligence among diverse units of employees. The role of knowledge management systems is to provide the exchanging intermediaries (or platforms) of explicit knowledge between knowledge contributors and knowledge seekers to assist knowledge sharing of employees in the organization. However, there is still a lack of deep understanding of the influence of the factors associated with personal motivation and social context on the usage of knowledge management systems in previous research. Based on social-psychological-technical perspectives, the purpose of this study is to develop the user acceptance model of knowledge management systems. An empirical survey of valid 233 responses from a engineering consultants firm in Taiwan shows that social context factors (organizational support, trust, and subjective norm), personal motivation factors (perceived usefulness and perceived enjoyment), and technology quality factors (perceived ease of use and output quality) are three key factors affecting the acceptance of the knowledge repository systems. Our findings also suggest interpersonal trust and institutional trust as two important dimensions of trust indirectly influence users’ attitude toward use and users’ intention to use system. In addition, among the antecedents, attitude toward use and subjective norm are two most salient variables to predict the construct of intention to us, while subjective norm and perceived usefulness are two most significant determinants of attitude toward use. It is worthy to mention that organizational support is the most important antecedent of subjective norm, whereas perceived ease of use is the most key antecedent of perceived usefulness and perceived enjoyment. The findings may be used as theoretical base for future research and offer empirical foresight to managers of organizations when the knowledge repository systems are being introduced initially into the organizations.
