In this paper, we use the data of internal capital market (ICM) to explore the effect of CFO character on the establishment of ICM. We have found that the salary of CFO affects the establishment and operation scale of ICM greatly. Specifically, the CFO salary is positively correlated with the ICM scale in the private enterprises (PEs) significantly. In addition to this, when we have explored the power of CFO on the establishment of ICM, we found that the two factors have a significant correlation. Specifically, when the CFO is a member of director board, then the ICM has a bigger scale in the PEs. Furthermore, when the CFO has a financial background, the firms are more likely to use ICM and have a larger operation scale, even more significantly in the PEs.
