中文摘要：

本文以2008-2011年间医药行业上市公司数据为样本,分别从平衡维度和交互维度实证检验了战略双元与企业绩效之间的关系,并进一步验证了战略双元在高管团队异质性与企业绩效之间的中介效应。研究结果表明：平衡维度与交互维度的战略双元均对企业绩效具有显著影响,说明企业在不同时点上探索——开发两种战略导向交互作用、动态匹配的复杂平衡关系对于企业绩效具有重要意义;同时,平衡维度的战略双元在高管团队教育异质性与企业绩效之间起完全中介作用,在高管团队职业异质性与企业绩效之间起部分中介作用。交互维度的战略双元在高管团队职业异质性与企业绩效之间起完全中介作用。

英文摘要：

An empirical analysis is made using the data between 2008 and 2011 based on 68 China＇s A- share listed companies in the pharmaceutical industry. We analyses the relationship between strategic ambidexterity and firm performance from Balanced Dimension（ BD） and Interactive Dimension（ ID）. The mediating effect of strategic ambidexterity between TMT heterogeneity and firm performance is also tested. The results of the empirical analysis show that strategic ambidexterity（ BD） mediates entirely the relationship between top management team（ TMT） heterogeneity in education and firm performance,and mediates partially the relationship between TMT heterogeneity in career experience and firm performance. Strategic ambidexterity（ ID） mediates entirely the relationship between TMT heterogeneity in career experience and firm performance.
