本文利用第八次全国私营企业抽样调查数据，考察了家族成员参与管理对我国企业技术创新活动的影响，以及这一影响如何因企业所处地区制度环境的不同而发生改变。采用研发投入作为技术创新投入度量指标、知识产权数量作为技术创新产出度量指标，在控制了企业特征、企业家特征、行业等因素后，研究发现：高管团队中的家族成员人数对企业创新投入和创新产出均存在显著正向影响；但随着所处地区制度环境的完善，这一正向影响有所减弱。上述研究结果表明，在我国当前转型经济背景下，家族成员参与管理仍然是促进家族企业技术创新的一种有效机制，特别是在制度环境更为落后的地区。

Using data from the Eighth National Private Firm Sampling Survey, this paper examines the impact of family involvement in management on Chinese private firms’ innovation activities, and further analyzes how this impact depends on local institutional environments. After controlling for other co-factors, the empirical results show that: (1) the number of family member on top management team has a significant positive effect on both firm’s innovation input and output; (2) the above effect is weaker in regions with better institutional environments, suggesting that in transition economy like China, family management is still an effective governance mechanism for firm’s innovation activities, especially for firms in regions with worse institutional environments.
