　　报告摘要：

　　The recent rise of dockless bike-sharingis dominated by two firms in China:one started first in 82 cities, 59 of which were subsequently entered by thesecond firm. Using these variations, we study how the entrant affects the incumbent’smarket performance. To our surprise, the entry expands the marketfor the incumbent. Not only does the entry boost its total number of trips andencourage more bike investment, it but also allows the incumbent to achievehigher revenue per trip, improve bike utilization rate, and form a wider andmore evenly distributed network. The market expansion effect on new usersdominates a significant marketstealingeffect on the incumbent’s old users.These findings, together with a theoretical model that highlights consumersearch and network effects, suggest that a market with positive network effectsis not necessarily winnertakesall,especially when users multi-homeacrosscompatible networks.
