This study applies a role transition approach to examine how the progress of new venture creation affects work-family conflict ( WFC) ． The paper contends that the identity confusion accompanied by the role transition serves as a stressor and intensifies the conflicts between family members and the focal entrepreneur， especially when the new venture is operating at an“in-between”phase． The progress of new venture creation therefore exhibits an inverted U-shape relationship with WFC． Moreover，the impact of role transition on WFC varies with the level of social support to entrepreneurship． Analyses of 201 nascent entrepreneurs from China support the hypotheses．
