$BBjL\!'(BHow can the Taxi Industry Survive the Tide of Ridesourcing? Evidence from Shenzhen, China.
Abstract: This talk discusses the impact of ridesourcing on the taxi industry and explores where, when and how taxis can compete more effectively. To this end a large taxi GPS trajectory data set collected in Shenzhen, China is mined and more than 2,700 taxis (or about 18% of all registered in the city) are tracked in a period of three years, from January 2013 to November 2016. The long sequence of GPS data points is first broken into separate $B!H(Btrips$B!I(B, each corresponding to a unique passenger state, an origin/destination zone, and a starting/ending time. By examining the trip statistics, we found that ridesourcing had worsened congestion during its expansion phase in 2015, but the overall impact was small. The taxi industry in Shenzhen has experienced a significant loss in its ridership since early 2015. Yet, the evidence is strong that the shock was relatively short and that the loss of the taxi industry had begun to stabilize since the second half of 2015. Data also show that taxi drivers had learned to cope with the competition from ridesourcing by gradually adjusting their search efforts to concentrate in areas with denser population and greater probability of generating profitable trips. We conclude that a dedicated service fleet with exclusive street-hailing access will continue to co-exist with ridesourcing and that regulations are needed to ensure this market operate properly.
