[[abstract]]Human capital enhances corporate competitiveness. In order to retain talent within organization, employee attitude becomes a critical issue. This study investigates the relationship between employee participation, trust and affective commitment. We take path analysis and find out that both perceptions of financial participation and degree of non financial participation are positively associated with affective commitment. Also, the relationship between financial participation and affective commitment was mediated by trust. However, trust doesn’t have complete mediation effects on the relationship between non financial participation and affective commitment. The result is offered to corporation officers for the reference of making human capital retention decisions.[[sponsorship]]Oxford Journal (ISSN 1551-4498); Association for Business & Economics Research (ABER)[[conferencetype]]國際[[conferencedate]]20120627~20120628[[booktype]]電子版[[iscallforpapers]]Y[[conferencelocation]]Cambridge, Englan
