The Impact of Market Power on Capital Misallocation: A Total Factor Productivity Perspective

The proper allocation of corporate capital is critical to sustainable business development, and misallocation of resources can impede sustainable economic growth and competitive markets. This study investigates the relationship between market power and capital misallocation in Chinese A-share listed companies, with a novel focus on the mediating role of total factor productivity (TFP). Using a comprehensive dataset of 20,818 firm-year observations from 2009 to 2021, we employ linear regression analysis to elucidate the mechanisms through which market power influences capital allocation efficiency. The results reveal a significant positive correlation between market power and capital misallocation, with TFP partially mediating this relationship. Specifically, a one-unit increase in the market power index is associated with a 1.106 unit decrease in TFP, and a 0.028 unit increase in the capital misallocation, indicating potential threats to long-term sustainability. This effect is more pronounced in non-state-owned enterprises, firms located in eastern regions, and those without shareholdings in financial institutions. These results contribute to the literature on market structure and resource allocation by providing empirical evidence of the detrimental effects of market power on capital allocation efficiency, operating through the channel of reduced productivity. Our findings have important implications for policymakers and firm managers, suggesting the need for targeted antitrust measures, promotion of market competition, and strategies to enhance TFP. This research advances our understanding of the complex interplay between market power, productivity, and capital allocation in emerging economies, offering valuable insights for addressing market failures, improving allocative efficiency and actively promoting sustainable business and sustainable socio-economic development in the Chinese context.
