With the accelerated development of global economic integration，cross-border e-commerce has become a crucial link connecting consumer markets across different countries and regions，experiencing unprecedented opportunities for growth. This report takes the “Four Little Dragons” of China’s cross-border e-commerce（Temu，TikTok，SHEIN，and AliExpress）as typical cases，delving into their development strategies and international communication practices. The report indicates that Chinese cross-border e-commerce platforms，through localized marketing strategies and innovative applications of social media，have effectively enhanced the global market recognition and competitive advantage of Chinese brands in regions such as the Americas，Europe，and Southeast Asia. However，challenges such as supply chain stability risks，logistics efficiency bottlenecks，and international trade compliance issues persist，posing threats to the robust development of cross-border e-commerce. Through in-depth analysis of industry data，the report reveals the key role of cross-border e-commerce in promoting global trade development，especially its significant impact on technological innovation，digital transformation，and the dissemination of national image and culture. As technology continues to advance and markets remain open，cross-border e-commerce is expected to achieve broader coverage and deeper integration on a global scale. Meanwhile，the report puts forward a series of strategic recommendations，including strengthening supply chain management，optimizing logistics systems，and enhancing the internationalization of brands，in order to jointly promote the sustainable development of China’s cross-border e-commerce worldwide.
