This paper identifies the causal effect of commute time on labor supply in urban China and provides implications for the development of active commuting. Labor supply is measured by daily workhours, workdays per week and weekly workhours, and city average commute time is adopted as an instrumental variable to correct the endogenous problem of individual commute time. We find that in urban China, commute time does not have effect on daily labor supply but has negative effects on workdays per week and weekly labor supply. These results are different from those found in Germany and Spain, and are potentially related to the intense competition among workers in the labor market of China. Moreover, the effect of commute time on workdays per week is stronger for job changed workers. In addition, the effects of commute time on labor supply are not different between males and females. Finally, policy implications for active commuting are discussed.
本文旨在识别通勤时间对中国城市劳动力供给的因果效应，并为积极通勤的发展提供启示。劳动力供给的衡量指标为每日工作时长、每周工作天数和每周工作时长，城市平均通勤时间被用作工具变量以校正个体通勤时间的内生性问题。我们发现，在中国城市，通勤时间对每日劳动力供给没有影响，但对每周工作天数和每周工作时长有负向影响。这些结果与德国和西班牙的研究结果不同，这可能与中国劳动力市场中工人之间的激烈竞争有关。此外，对于换工作的工人，通勤时间对每周工作天数的影响更大。此外，通勤时间对劳动力供给的影响在男性和女性之间没有差异。最后，讨论了积极通勤的政策意义。
