On December 19, 2023, Gelonghui reported that STO Express Co.,Ltd. (002468.SZ) stated on the investor interaction platform that the scale of franchise express companies has basically reached an average of over 50 million orders per day. The marginal cost reduction effects brought by scale effects still exist, but the cost reduction space, especially in the transshipment link, may gradually narrow. In terms of delivery costs, there is hope to further reduce costs and improve delivery efficiency in the future by continuing to enhance the automation level of outlets, direct distribution from distribution stations, and increasing the proportion of delivery by unmanned vehicles.
