- Notes. The full sample range from 2006 to 2016. A bank is defined as diversified if it has subsidiaries in more than one city. The sample is divided according to the bank–year observations; a bank can be diversified in one year and non-diversified in another year. Thus, appearing in both groups. All variables defined in the Appendix. a, b, and c denote statistical significance at 10%, 5% and 1% levels, respectively. The original amount of equity, NPL, fixed asset, and non-interest income is reported instead of log form (in units of million yuan)
