This paper investigates the impact of regional corruption on the cost of capital in firm. Relying on provincial-level corruption data in mainland China from 2003 to 2013, we find regional corruption has a significantly positive relationship with the cost of debt capital, and the positive relationship is stronger in non-SOEs, but regional corruption has not significantly relationship with the cost of equity capital. To some extent, listed companies’ financing activities are influenced by the regional corruption level, especially for non-SOEs.
