This text examines the rapid evolution of instant delivery services in China, where smartphones facilitate one-hour delivery for a wide array of retail goods beyond simple food orders. It highlights how major players like JD.com and Alibaba are driving this shift toward "short-distance e-commerce" to meet the needs of busy, urban consumers, particularly working mothers. The author explains that while these services offer extreme convenience and easier package reception, they require retailers to undergo massive structural reforms in logistics and inventory management. Using the example of Watsons, the source illustrates the technical difficulties of synchronizing online and offline stock, which can lead to consumer frustration. Ultimately, the text argues that successful integration of instant delivery demands a total commitment to digital transformation rather than half-hearted operational changes.
