摘　　要：中国产业结构演变的一个重要特征是服务业比重上升,而这是否会加大经济稳增长压力,亟待进一步探讨。运用熵值法及效率分析法测度各城市数字经济发展水平和城市服务业生产率,并基于2011—2019年中国地级市面板数据检验数字经济发展对服务业生产率的影响。结果显示:数字经济发展显著提升了中国城市服务业生产率,且空间溢出效应和门槛效应明显。异质性分析表明,数字经济为东部地区以及大数据综合试验区城市服务业带来的“数字红利”更大。进一步检验发现,数字经济对服务业生产率的促进作用大于对制造业生产率。数字经济改变了“鲍莫尔成本病”发生的前提,从而打破了“成本病诅咒”。由此可见,数字经济时代,服务业不是经济增长的绊脚石,服务业比重上升是经济高质量发展的必然途径和表现形式。This paper uses entropy method and efficiency analysis method to measure the digital economy development index and service industry productivity of each city.Based on the panel data of China's prefecture level cities from 2011 to 2019,this paper tests the impact of digital economy development on service industry productivity.The research shows that the development of digital economy has significantly improved the productivity of China's urban service industry,and the spatial spillover effect and threshold effect are obvious.Heterogeneity analysis shows that the digital economy brings greater“digital dividend”to the urban service industry in the eastern region and the big data comprehensive pilot area.Further inspection shows that the digital economy promotes the productivity of the service industry more than that of the manufacturing industry.The digital economy has changed the premise of“Baumol cost disease”,thus breaking the“cost disease curse”.In the digital economy era,the service industry is not a stumbling block to economic growth,and the rising proportion of the service industry is an inevitable way and manifestation of high-quality economic development.
