生产性服务业与其他产业的互动关系--基于历次投入产出表的分析

Interaction Relationship between Productive Services and Other Industries

本文首先界定了生产性服务业的内涵和外延,并根据分析的需要重新调整组合了国民经济部门数据,把生产性服务业划分为劳动密集型、资本密集型和知识技术密集型三大类。利用历次的投入产出表和延长表系统地计算了直接消耗系数、完全消耗系数、影响力系数和感应度系数,在此基础上分析了不同类型的生产性服务业与其他主要产业部门的关系,以及它们在我国国民经济中的地位。得出结论:生产性服务业总体与其他产业的联系比较弱,而与制造业特别是先进制造业的产业关系最为密切,不同类型的生产性服务业与其他产业的关系表现出一定的差异性。并提出相应的发展政策建议:增加生产性服务业的有效需求,优化需求结构,调整供给结构,促进与其他产业的良性互动。

This paper first defines the connotation and extension of productive services, then readjusts and composes national economy sector data based on the demand for analysis. This paper divides the producer services into 3 categories： labor-intensive, capital- intensive, and knowledge and technology intensive, uses previous input-output tables and extension tables to calculate the direct consumption coefficient, total consumption coefficient, influence coefficient and induction coefficient, analyzes the relationship of different types of productive services with other major industry sectors and their status in our national economy. The paper puts forward： productive services takes weak linkages to other industries in general, while tight linkages to manufacturing industries, esp. advanced manufacturing industries. There are also some differences between different types of productive services and other industries. Then the paper proposes some suggestions： increasing the effective demand of producti,（e services, optimizing the demand structure, adjusting the supply structure, and promoting positive interaction with other industries.
