英文摘要：

At the background of China＇s traditional culture and economic transformation, the effect of entrepreneurs＇ social networks on enterprises＇ growth has been an important topic attracting attention from both academic and practical fields. This paper decomposes entrepreneurs＇ social networks into three dimensions： entrepreneurs＇ external horizontal social networks representing interactions with other economic entities, entrepreneurs＇ external vertical social networks indicating interactions with governments, and entrepreneurs＇ internal vertical social networks representing entrepreneurs＇ control over daily operations. The empirical analysis indicates that under current institutional circumstances entrepreneurs＇ social networks play a positive effect on enterprises＇ growth. Among the three kinds of social networks entrepreneurs＇ external horizontal social networks play the most influencing role while the effect of the other two kinds of networks can not be neglected either.
