While many studies have devoted to the industries for VoIP research, less attention has been paid to the public sectors. This thesis conducts an empirical study of intention of VoIP adoption for the public sectors in Kinman. Based on the technology acceptance model, the study constructs the research model by integrating innovation diffusion theory and theory of planned behavior to define such factors as system quality (external factor), perceived usefulness, perceived ease of use, perceived compatibility, key quantity of users, cost, behavior attitude, and adoption intention. There are 263 valid questionnaires returned. Structure equation model is established to derive the results. Research findings indicate that: (1) there are almost 65% subjects spending less than 400 NTD in VoIP, and voice quality and content functions are not as good as expected; (2) The perceived usefulness, perceived ease of use, perceived compatibility, key quantity of users, and cost are all significantly influenced by system quality; (3) The behavior attitude is not significantly influenced by perceived ease of use, but can be improved by increasing the degree of perceived usefulness and perceived compatibility, and key quantity of users; (4) Cost is significantly related to behavior attitude while insignificantly and negativly related to the adoption intention. The former is significantly while the later is insignificantly, indicating that users are instantaneously reject using VoIP for high cost, but may accept it with higher quality such as usefulness, ease of use, compatibility, and many users.
