摘要：
This study examines how related and unrelated variety at the regional level are correlated with establishment-level R&D investment in the environmental industry in Korea. We find a positive correlation between unrelated variety and R&D investment, while related variety does not show a significant correlation. Additionally, the relationship between unrelated variety and R&D investment varies with establishment size. Unrelated variety has positive externalities only for micro establishments and has no clear effects on small, medium, and large establishments.
