ABSTRACT: Based on the panel data of 16 listed banks in China from 2004 to 2014, this paper makes empirical analysis to examine the relationship between bank’s capital buffer and macroeconomic fluctuations or income diversification. The results show that the banks’ income diversification has negatively correlation with macroeconomic fluctuations. It means the banks’ capital buffer behaves in a counter-cyclical way, and different bank ownership structure or capital level also has asymmetric influence in expansion and slack time. What’s more, the non-interest income of bank has a significant negative impact on capital buffer and its periodicity. The diversification of bank income structure not only reduces the bank’s capital buffer level, but also weakens the counter-cyclical characteristics of capital buffer. At the same time, the diversification of the income structure of the bank with high capital adequacy ratio has no obvious effect on the counter-cyclical characteristics of the capital buffer. Based on the above conclusions, this paper believes that the regulatory authorities in the implementation of the counter-cyclical capital regulation should fully consider the impact of bank income structure and bank capital levels.
