进口技术外溢、关联效应与我国产业部门效率水平提升研究

Import Technology Spillover,Correlation Effect and Industrial Productivity

在考虑国别和行业层面研发知识源构成情况异质性前提下,本研究基于制造与服务行业投入-产出关系表,构造了考虑制造业和服务业关联效应下的多样化进口技术外溢,并由此考察了其对我国相关产业部门效率水平提升的影响。分析证实:(1)在考虑本土产业间和产业内关联效应的情况下,进口技术外溢对我国各产业部门效率水平的提升作用均非常明显,关联效应起到了重要"催化"作用;(2)尤其关联效应下,相比各产业部门内直接进口技术外溢,无论制造业还是服务业,通过间接进口技术外溢获得的效率水平提升均更加突出;(3)受关联效应下的逆向需求和前向投入关联影响,制造业或服务业进口技术外溢均表现出对另一方效率水平提升更显著的推动作用。

Based on trans-national and trans-industrial panel data,and by full consideration of heterogeneity of knowledge in both country side and industry side,also in consideration of industrial correlation effect between manufacture and service,this paper mainly focuses on technology spillover of import and its diversified decomposition characteristics,and their influence on improving of related industrial productivity.The main findings show：（1） in consideration of intra-industrial and inter-industrial association effect,technology spillover of import has an apparent influence on improving of industrial productivity,enhanced association effect here plays an important catalytic role.（2） under influence of association effect,and compared with intra-industrial association effect,inter-industrial association effect plays a more prominent role in promoting productivity of both manufacture and service.（3） through association of reverse requirements and forward input,technology spillover in manufacture and service both have more important influence on improving of productivity in each other.
