中国地方政府加班的时空格局及经济效应OA

For a considerable period following China's reform and opening-up,local governments were required to make substantial efforts to promote economic growth,primarily by improving administrative governance efficiency through overtime work.Existing research has focused on overtime in the private sector but has paid limited attention to overtime in the public sector,particularly in local governments.Whether an optimal range of local government overtime exists and how overtime relates to economic growth remain unclear.Accordingly,this study uses high-frequency satellite nighttime light data to measure the intensity of local government overtime in China from 2012 to 2024.The Jenks natural breaks classification method is used to illustrate the spatial distribution of overtime intensity among different groups of local governments.Markov chains are employed to examine the dynamic evolution of overtime intensity,while the Theil index is used to identify regional differences and their sources.Finally,econometric models are used to test the economic effects and underlying mechanisms of local government overtime.The findings are as follows:(1)The intensity of local government overtime in China exhibits fluctuating upward and downward trends,as well as a spatial distribution characterized by higher levels in the north and lower levels in the south.(2)The intensity of local government overtime is relatively stable,although cross-level transitions remain possible.Overtime intensity in neighboring areas also has significant spatial spillover effects on individual cities.(3)Regional differences in the intensity of local government overtime have decreased.The interregional Theil index is higher than the intraregional index,indicating that differences between regions are the primary source of variation in local government overtime.(4)Local government overtime has an inverted U-shaped impact on urban economic growth,with administrative governance efficiency playing a substantial role in this relationship.This study makes two academic contributions.First,it extends the use of satellite nighttime light data,which have previously been applied to depict overtime in enterprises,to the measurement of local government overtime intensity.This extension broadens the method's application from the enterprise level to the government level.The study also examines the spatiotemporal patterns of local government overtime using time-series data,thereby providing empirical data for further research on overtime among local governments.Second,this study proposes and tests the inverted U-shaped impact of local government overtime on urban economic growth through changes in administrative governance efficiency.The findings demonstrate that continuously increasing overtime intensity to improve administrative governance efficiency and promote urban economic growth is not advisable.They therefore provide empirical support for further advancing policies aimed at reducing the burden on local governments.
