Throughout the protracted three-year COVID-19 pandemic, China’s express logistics industry has exhibited remarkable resilience and robust growth, thereby ensuring the seamless continuity of package delivery services. This paper aims to assess the resilience of Chinese express companies’ Elastic Logistics Platforms (ELPs). The study selects a sample set based on the Concentration Ratio (CR) of prominent express and parcel service brands. Drawing on annual reports from 2019 onwards, the research employs an information technology-driven analytical model to examine the innovative adaptability of ELPs across diverse scenarios. The express products are systematically categorized into three types: (1) Domestic standard and expedited services, complemented by premium specialized products, which underscore the industry’s commitment to product diversification and market competition, while simultaneously integrating with the agricultural and manufacturing sectors. (2) Local and on-demand delivery services, which focus on consolidating distribution terminals and innovating last-mile logistics, thereby bridging real-time consumer demand with efficient logistics operations. (3) International services that bolster the “dual circulation” strategy and contribute to a cohesive domestic market approach. The findings of this analysis are set to guide the development of multi-channel marketing strategies and policy choices, aiming to enhance the express logistics industry’s prosperity and sustainability.
