Abstract: With the increase in greenwashing, corporate greenwashing governance has become a crucial component of urban environmental management. Industrial clusters are a key form of urban economic organization, yet the mechanisms through which they affect corporate greenwashing remain unclear. This study examines how different types of industrial agglomeration influence corporate greenwashing using a sample of Chinese A-share listed companies. The key findings include the following: (1) Specialized agglomeration inhibits corporate greenwashing through a “supervision” effect generated by intra-industry competition, while diversified agglomeration exacerbates greenwashing via a “collusion” effect arising from inter-industry cooperation. (2) The inhibitory role of specialized agglomeration is amplified under conditions of low public and strong government environmental concern, while the promotional effect of diversified agglomeration becomes more pronounced in contexts of high public and weak government environmental concern. Government environmental concern can be categorized into “general” and “specific” types, with the former being more effective in governing corporate greenwashing. (3) Specialized agglomeration demonstrates superior efficacy in curbing greenwashing among firms with green innovations related to energy-saving, alternative energy production, waste management, and transportation, while diversified agglomeration intensifies greenwashing tendencies in firms without green innovations. (4) Collusive greenwashing under diversified agglomeration yields short-term firm value gains but incurs hidden costs, including elevated operational risks and declining profit margins. This research provides critical insights for promoting corporate green transition and fostering zero-carbon industrial clusters.
