共享出行对道路交通伤亡事故的影响

Impact of Ride Sharing on Traffic Deaths and Injures

基于2004—2016年中国65个地级市交通事故伤亡数据,使用双重差分的方法研究了共享出行对道路交通安全的影响。结果表明:短期内,"滴滴出行"的出现使得一二线城市道路交通死亡人数显著增加,西部地区相对于东部和中部地区交通事故死亡人数显著减少,受伤人数区域间无显著差异;长期来看,"滴滴出行"的出现对道路交通死亡人数和受伤人数均无显著影响。

Based on the traffic accident data of 65 cities in China from 2004 to 2016,this paper studies the impact of ride sharing on road traffic safety using DID strategy.Results show as follows:in a short period,the entry of "didi chuxing" increases traffic accident deaths significantly in the first-tier and second-tier cities,reduces traffic accident deaths in the western region significantly compared with that in the eastern and central regions;the number of injuries is not significantly different among regions;in the long run,the entry of "didi chuxing" has no significant impact on road traffic deaths and injuries.
