In this paper, we analyze whether leverage had impacts on investment in the period 1999-2009, and whether these impacts, if they exist, differed among companies with different investment opportunities and with different major shareholders. In order to identify governance with different major shareholders, we grouped China's listed firms into central government owned firms (CSOEs), local government owned firms (LSOEs) and non-state-owned firms (NONSOEs). Our results are as follows. First, our analysis reveals that leverage does have significantly negative impacts on CSOE, LSOE and NONSOE investments. Secondly, in LSOEs and NONSOEs, negative leverage impacts on low-growth firms are stronger than average firms, implying that a disciplinary effect of leverage over investment can be found in LSOEs and NONSOEs. Finally, however, no such effect can be observed in CSOEs. We have provided a first finding that the effect of leverage varies according to a firm's major shareholders.
