制造业集聚对企业创新"增量提质"的影响研究OACHSSCD

Manufacturing agglomeration serves as an important source of enterprise innovation.Based on data from Chinese A-share manufacturing listed companies from 2007 to 2024,this paper empirically examines the impact and mechanism of manufac-turing agglomeration on the"quantity increase and quality improvement"of enterprise innovation.The results show that manufactu-ring agglomeration can significantly promote the"quantity increase and quality improvement"of enterprise innovation,and this con-clusion remains valid after endogeneity tests and robustness tests.Mechanism analysis indicates that manufacturing agglomeration mainly promotes the"quantity increase and quality improvement"of enterprise innovation through the institutional environment opti-mization effect,the factor allocation efficiency improvement effect,and the digital transformation effect.Heterogeneous analysis in-dicates that the promoting effect of manufacturing agglomeration on the"quantity increase and quality improvement"of enterprise in-novation is more pronounced among large-scale enterprises,high-productivity enterprises,industries with high competition intensi-ty,and central and western regions.This study provides empirical evidence and decision-making references for optimizing manufac-turing agglomeration policies and promoting simultaneous improvements in the quantity and quality of enterprise innovation.
