Linkage between commuting time and sickness absence in the context of China: transmission channels and heterogeneous effects

Abstract Background Most of employees in urban China have experienced a heavy commuting burden,which has become an urgent issue that should be solved in the process of new urbanization strategy. However, not only has the exploration of relationship between the commuting and sickness absence been still scant in China, but also there is no discussion made to analyze the mechanism linking the commuting time and sickness absence. To address these gaps, this study firstly investigates the commuting-absence effect as well as the potential transmission channel between them. Methods Using a unique dataset of 2013 Matched Employer-Employee Survey (CMEES) in China, we apply the zero-inflated negative binomial model to explore the nexus between the commuting and sickness absence. To discuss the potential mechanism linking commuting and sickness absence in the context of China, the estimations of the commuting on health-related outcomes and work efforts are performed by the OLS and Logit regression to discuss the mechanism. Results The empirical results reveal that the commute has a positive effect on sickness absence, while it is still robust against several specifications. More importantly, the commuting-absence effect is mainly transmitted through health-related outcomes of employees, whereas we find no clear evidence supporting the shirking behaviors. Additionally, the heterogeneous effects of commuting-absence are differentiated across the Hukou status, gender, transportation modes, scale of cities and types of enterprises. Conclusion The longer commute induces to lower productivities through the sickness absence, that is, the longer journey from home to work is positively related with the increasing sickness absence, which keeps in consistency with previous studies. And the potential effect of commute-sickness absence is mainly transmitted through their health-related outcomes. Additionally, the impacts of commute time on sickness absence are differentiated across the Hukou status, gender, transportation modes, scale of cities and types of enterprise.
