The wide acceptability of ICTs and social media enriches the delivery platform of e-government (E-gov) services. The public can explore problems, provide ideas, and design solutions to improve E-gov services (EGS) in a convenient and timely manner. The role of the public transforms from passive users to active, informed partners or co-creators of EGS innovations and problem solving. However, value cocreation is an interactive process, and service value can only be created through joint efforts of all participants. This study builds an influence factor model of public engaging intention towards EGS value co-creation, based on technology acceptance theory, trust theory, and motivation theory, to explore the impact factors and impact paths. Comprehensive validation is further conducted through path analysis using structural equation modeling (SEM) methods. Path analysis interprets how the public will accept and adopt value co-creation behavior for EGS. The results presented in this study might be helpful for government policymakers or IT managers seeking to enhance EGS value creation through designing more effective incentive mechanisms. This study also introduces a comprehensive picture of the potential paradigm of public service value creation in an era of increasing user dominance.INDEX TERMS E-gov service, value co-creation, technology acceptance, public engaging intention, social media.
