Abstract:This paper empirically examines the impact of entrepreneurship-family conflict on new venture performance, and the moderation effect of conflict coping strategy and entrepreneurs’ self-efficacy. It finds that, firstly, in case of time-based entrepreneurship interference with family, the new venture performance would be much better, reflecting both on employee scale and sale revenue. On the other hand, if entrepreneur is involved too much in family affairs, time-based family interference with entrepreneurship would have a negative impact on new venture performance. Secondly, conflict coping strategy played a moderation role on the relationship between entrepreneurship family conflict and new venture performance.
