Strategic Practice of “Core Category Deep Cultivation + Diversified Supplement” in Small and Medium-Sized Medicinal and Chemical Foreign Trade Enterprises: A Multiple-Case Study Based on Resource-Based View and Dynamic Capability Theory

Small and medium-sized medicinal and chemical foreign trade enterprises generally face strategic dilemmas such as weak risk resistance due to single-category operation and resource dispersion caused by blind diversification. Based on the Resource-based View (RBV) and Dynamic Capability Theory (DCT), this study takes Wuhan Kuda Hui Trading Co., Ltd. as the core case and selects three other enterprises of the same scale with different strategic types for comparative analysis. This study explores the internal logic and implementation paths of the “Core Category Deep Cultivation + Diversified Supplement” strategy. The findings reveal that this strategy accumulates heterogeneous resources through core categories and leverages dynamic capabilities to achieve synergistic expansion of supplementary categories, effectively balancing resource efficiency and risk resistance. Moreover, this study proposes a four-stage implementation path, including category selection, resource deep cultivation, diversified expansion, and synergistic optimization. The quantitative dimensions and implementation models of this strategy are industry-compatible. The conclusions provide a theoretical framework and practical guidance for small and medium-sized medicinal and chemical foreign trade enterprises to break through strategic dilemmas.
