Alliance formation research suggests that choosing appropriate alliance forms is an important mechanism in achieving cooperative goals．This study extends prior alliance formation research by bridging two previously separated domains—entrepreneurship and strategic alliances—together． Specifically，we explore the in_x005ffluences of entrepreneurial orientation on a set of decisions involved in the alliance formation process，including decisions on alliance governance structure，alliance scope，and planned time boundedness．Moreover，we also examine the moderating effects of past alliance experience on the relationships between entrepreneurial orientation and alliance formation decisions．Data on 205 paired partner firms in China indicate that a higher level of entrepreneurial orientation will be associated with equity-based governance structure，broad alliance scope，and open time boundedness．Results also suggest that past alliance experience positively moderates the relationship between entrepreneurial orientation and planned time boundedness．
