摘要
Driven by globalization and digitalization, electronic commerce has fundamentally transformed the global business landscape (Yang et al. 2025). Global e-commerce is projected to generate USD 5.5 tn in revenue by 2027 at a steady 14.4% compound annual growth rate (CAGR; ITA 2024). This continued growth has driven the rise of international e-commerce firms (ECFs), which sell physical products through their own online shops or marketplaces to consumers (Li et al. 2025; Swoboda and Sinning 2022).
