摘　　要：本文提取了我国2013—2021年裁判文书网中交通事故案件信息,以本外地原告的胜率差异来测度本地偏好程度。回归结果显示,外地诉讼方的胜率要显著低于本地,这种差异具有较强的外生性和稳定性。基于地级市本地偏好指数和城市间贸易流数据,本文还发现,本地偏好对国内贸易存在显著的负面影响,其作用机制为增加了贸易成本,造成了贸易转移和挤出效应。本文证实了本地偏好对国内贸易的重要影响,为建设全国统一大市场提供了新的思路。This study extracts information on traffic accident cases from China's judgment document from 2013 to 2021, and measures local bias based on the difference in win rate between non-local and local plaintiffs. We find that the win rate of the non-local is significantly lower than that of the local, and it has strong exogeneity and stability. By estimating the local bias of cities and combining the estimation with trade data, we find a significant negative impact of local bias on trade, increasing trade cost, resulting in trade diversion and crowding out effect. Our findings confirm the important influence of local bias on domestic trade.
