生产性服务进口复杂度对制造业全要素生产率的影响研究

T he influence of productive service import complexity on T FP of manufacturing industry

作为高级要素投入,生产性服务进口会对制造业全要素生产率(TFP)的提升产生推动作用。从直接效应和间接效应两个角度,分析生产性服务进口复杂度作用于制造业TFP的机理,在此基础上,利用1999—2015年的面板数据,引入本土生产性服务作为中介变量,对生产性服务进口复杂度对制造业TFP的影响进行实证分析。结果表明:(1)从总体层面看,生产性服务进口复杂度能显著促进我国制造业TFP的提升。(2)从生产性服务分部门来看,随着行业知识密集度变高,生产性服务进口复杂度对制造业TFP的影响逐渐变"弱"。(3)本土生产性服务在生产性服务进口复杂度对制造业TFP的影响中起到部分中介作用。

As a senior element input,the import of productive service will promote the promotion of TFP in the manufacturing industry. This paper studies the influence of productive service import complexity on the TFP in manufacturing from the angles of direct effect and indirect effect. By using panel data from 1999 to 2015 and the intervening variables,the results show that：（ 1） Generally speaking,complexity of productive service can promote the improvement of China＇s manufacturing TFP.（ 2） In terms of the division of producer services,the complexity of the import complexity of productive services has gradually weakened the impact on TFP of manufacturing industry,as the industry has become more knowledge-intensive.（ 3） The local producer services play a part in the effect of the productive service import complexity on manufacturing TFP.
