The existing literature on political capital and bank lending has largely overlooked the role of political environment. Based on the theories of political marketplace, all-pay auction and political instability, we examine the conditional effect of political capital on access to bank loans with political environment surrounding private firms changing, using a nationwide survey of private firms in 2010. In particularly, we characterize the political environment with political capital inequality and political instability. We find that private firms have more difficulty gaining access to bank lending with the increase in the degree of political capital inequality. Furthermore, political capital exerts a positive effect on access to bank loans only when political capital inequality within a province exceeds 0.4775 and political instability does not exceed 0.7.
