Through empirical analysis, it was found that the diversification measure (HHI) was significantly negatively correlated with the corporate performance indicator (ROA);meanwhile, capital structure (total debt leverage and long-term debt leverage) played a mediating role in the process of diversification strategy affecting corporate performance. The research results indicate that by optimizing their capital structure, enterprises can effectively enhance operational performance when implementing diversification strategies, thereby promoting their development and growth. This finding provides empirical support and theoretical basis for the implementation of diversification strategies by manufacturing enterprises.展开更多
