要素市场扭曲、双重抑制与中国生产性服务业全要素生产率:基于中介效应模型的实证研究

Factor Market Distortion,Dual Inhibition and Total Factor Productivity of Producer Services Industry of China——An Empirical Research Based on Mediating Effect Model

本文从社会网络和产业演化的角度,系统考察了要素市场扭曲对我国生产性服务业全要素生产率的双重抑制机理,并构建中介效应模型,以我国2004—2010年的省份面板数据进行了实证性检验。研究发现,转轨时期我国正规要素市场的扭曲导致生产性服务企业畸形依赖社会网络特别是政府关系网来获取生产要素,由此导致的经营目标短期化直接抑制了我国生产性服务业的全要素生产率。同时,要素市场扭曲还通过制约制造业的演化进程间接抑制了我国生产性服务业全要素生产率的提升。要想切实促进我国生产性服务业的增长,必须系统性地纠正要素市场扭曲对生产性服务业效率的双重抑制。

From the perspectives of the social metwork and manufacturing industry evolu- tion, this paper investigates an important dual inhibition mechanism of the factor market distortion on the total factor productivity of Producer Services in China. We establish a me- diating effect model theoretically, and test it empirically by using the panel data of different provinces in China. The results show that the Producer Services companies are overlyrelying on social networks, specially the networks of government relationsip, to obtain factors of production because of the formal factor market distortion in transition period. Itleads toshort- term business objectives os enterprises and inhibits the total factor productivity of Producer services directly. What＇s more, the factor market distortions can restrict the evolution of the manufacturing industry, which further inhibits the growth of Producer Services＇total factor productivity indirectly. Inorder to promote the development of Producer Services effectively, systematic adjustment policies must be applied tocorrect the dual inhibition of factor market distortion on total factor productivity of the Producer Services in China.
