【摘要】：文章首先对开放经济技术溢出理论进行了推导,在此基础上构建出技术溢出计量模型并利用我国1990-2010年的工业分行业数据,对我国工业行业国内研发、进口和出口对全要素生产率的水平效应和垂直效应进行了分析。对全要素生产率的估计使用半参数方法以避免内生问题,对计量模型使用普通最小二乘法(OLS)和动态最小二乘法(DOLS)进行回归。最后结果表明,国内研发显著的促进了生产率提高;进口的水平溢出为负,而垂直溢出为正;出口的水平溢出为正,但垂直溢出为负,且就绝对值来看,出口的水平效应远大于进口的水平效应。所以一方面要进一步加强对进口技术的消化吸收,进一步促进进口的垂直效应;另一方面也要改变目前劳动密集型的出口方式,加大出口的技术含量,转变出口垂直效应为负的现状。
[Abstract]:Firstly, this paper deduces the theory of technology spillover in open economy, and then constructs the measurement model of technology spillover and makes use of the industrial data of China from 1990 to 2010 to research and develop the domestic industry in China. The horizontal and vertical effects of import and export on TFP are analyzed. The semi-parametric method is used to estimate the total factor productivity (TFP) to avoid the endogenous problem, and the ordinary least square method (OLS) and the dynamic least square method (DOLS) are used to regression the econometric model. The results show that domestic R & D significantly promotes productivity improvement; horizontal spillover of imports is negative, while vertical spillover is positive; horizontal spillover of export is positive, but vertical spillover is negative, and in absolute terms, The horizontal effect of export is much larger than that of import. Therefore, on the one hand, it is necessary to further strengthen the digestion and absorption of imported technology and further promote the vertical effect of import; on the other hand, it is also necessary to change the current labor-intensive export mode and increase the technical content of export. Change the export vertical effect to negative status quo.
