Abstract：Data from Chinese A-share listed companies spanning 2OlO to 2O21 were analyzed to investigate the potential impact of national urban agglomeration construction on the capacity utilization rate of manufacturing enterprises and its mechanisms. National Urban Agglomeration planning was used as a quasi-natural experiment. The difference-indifferences method was applied for empirical analysis. Results show that national urban agglomeration construction significantly increases the capacity utilization rate of enterprises. This effect is more evident in state-owned enterprises， traditional manufacturing firms，and companies in central and western regions. The improvement occurs through industrial agglomeration，human capital enhancement，alleviation of financing constraints， and optimization of the business environment.
