This study is a pre-test research conducted before introducing an evoting system by Korean e-Government. The purpose of this empirical study is to establish research hypotheses based on UTAUT model of Venkatesh et al. and to prove causal relationships among defined factors influencing on user acceptance for an e-voting system. In Korea, though actual user groups were extremely limited, we collected data from 116 persons who had experienced trial operation for this e-voting system and derived both theoretical and practical propositions and implications. As the result of this study, including the new variable of 'ubiquity' in consideration of the specific characteristics of evoting, overall variables defined in this research model are examined partially by means of empirical analysis process to identify the statistical significance. The outputs of this research may provide theoretical basis and political implication necessary for developing countries' planning to introduce e-voting in the future.
