Entrepreneurship plays a pivotal role in driving economic development and social progress. In contrast to existing literature that primarily focuses on the impact of zombie enterprises on innovation, resource distortion, and environmental pollution, this study aims to investigate the influence of zombie enterprises on entrepreneurship by utilizing data from prefecture cities in China. Additionally, we explore how banking competition moderates this relationship. Employing the system GMM estimator, our findings reveal that zombie enterprises significantly hampers urban entrepreneurship quantity and diminishes entrepreneurship quality. Furthermore, the inhibitory effect of zombie enterprises on entrepreneurship quality is greater than that of entrepreneurship quantity. In addition, we observe that state-owned zombie enterprises have a more pronounced negative impact compared to private zombie enterprises. Notably, banking competition exhibits a nonlinear moderating effect on the association between zombie firms and entrepreneurship; joint-stock banks and city commercial banks play prominent roles in shaping this effect. Threshold model regression analysis confirms these nonlinear effects. Overall, our conclusions offer important policy implications for accelerating the disposal of zombie firms as well as enhancing entrepreneurship quantity /quality to promote high-quality urban development. Plain language summary: Zombie firms, banking competition, and urban entrepreneurship Entrepreneurship plays an important role in economic development and social progress. Different from the existing literature that concerns the impact of zombie enterprises on innovation, resource distortion, and environmental pollution, this paper attempts to study the effect of zombie enterprises on entrepreneurial behavior from the dimensions of quantity and quality. Based on the data from prefecture cities in China, this paper examines the impact of zombie enterprises on entrepreneurial activity and quality and focuses on the moderating effect of banking competition on this relation. The study finds that the degree of zombification has a significant inhibitory effect on urban entrepreneurial activity and entrepreneurial quality, the inhibitory effect of zombification on entrepreneurial quality is stronger than that on entrepreneurial activity, and the inhibitory effect of state-owned zombie enterprises on entrepreneurial behavior is greater than that of private zombie enterprises. Banking competition has a nonlinear moderating role in the inhibitory effect of zombie enterprises on entrepreneurship, and this moderating effect is mainly produced by joint-stock banks and city commercial banks. The threshold model regression further confirms the existence of nonlinear moderating effects. The conclusions of this paper provide policy implications for accelerating the disposal of zombie enterprises, enhancing entrepreneurial activity and quality, and promoting high-quality urban development.
