外生和内生两个视角下服务业结构对生产率的影响

Impact of Service Industries Structure on Productivity in Exogenous and Endogenous perspective

现代经济中新的服务行业和新的服务方式不断出现,导致服务行业之间的差异越来越大,服务行业之间的结构对整体经济的影响也越来越大。本文在李建华和孙蚌珠对服务业结构分析的基础上,扩展Pugno和程大中的模型,将服务业结构对生产率的影响分解为两个部分,一部分是服务业结构对生产率的外生影响,另一部分是服务业结构对生产率的内生影响,即居民家庭通过不可标准服务消费提高人力资本积累水平,进而提高生产率。通过建立计量经济模型,从影响方式和影响强度两个方面实证服务业结构对生产率的外生影响和内生影响。

With new service industries and new service mode emerge in modem economy, the difference of service industry becomes more and more obvious, and service structure has much impact on economy. This paper extends the model of Pugno （2006） and Cheng （2010）, based on Structural criteria for the classification services of Li ＆ Sun （2012）. The impact of service industry structure on productivity is divided into two parts： one part is exogenous impact, and the other part is endogenous impact that un-standardized service consumption Improve human capital accumulation, and then improve productivity. This paper analyze the way and strength of exogenous impact and endogenous impact by empirical research.
