基于2012-2022年沪深A股1081家上市公司数据，研究发现区域文化多样性通过促进企业战略联盟来提升环境创新，且知识基础广度正向调节、深度负向调节这一效应。
ABSTRACT Culture significantly influences corporate strategic behavior and performance. Based on institutional theory and resource‐based perspective, this study constructs a relational model integrating regional cultural diversity and firms' strategic alliances, knowledge base, and environmental innovation. Using 1081 Shanghai and Shenzhen A‐Shares listed firms (2012–2022) as samples, it conducts multiple regression analysis to examine the effect of regional cultural diversity on firms' environmental innovation, the mediating role of strategic alliances, and the moderating role of the knowledge base. Findings show that regional cultural diversity positively affects firms' environmental innovation, which is mediated by strategic alliances. It also shows that this effect is positively moderated by the breadth of the knowledge base but negatively moderated by the depth of the knowledge base. These findings suggest promoting the protection and integration of regional cultural diversity and accelerating the formation of corporate strategic alliances to enhance firms' environmental innovation capabilities.
