Does banking competition increase corporate labor income share? Evidence from China

This paper investigates the impact of banking competition on corporate labor income share in China. Utilizing hand-collected unique data on bank branches within a certain distance of firms and a large sample of Chinese A-share list firms spanning the period 2000-2022, we find that banking competition significantly boosts corporate labor income share. A 10 percent increase in banking competition, the corporate labor income share increases by 0.06 percent on average. The results remain robust after replacing proxies, changing estimation methods, controlling for other shocks, and addressing endogenous concerns. Easing financing constraints, improving investment efficiency, and enhancing human capital are three essential channels through which banking competition promotes corporate labor income share. We also find that the impact of banking competition on corporate labor income share is more pronounced for firms with higher external financing dependence, higher financing gaps, more investment opportunities, higher governance efficiency, and higher information asymmetry. Our findings highlight the significance of enhancing banking competition to promote income distribution, foster common prosperity, and drive high-quality economic development.
