我国电子信息制造业技术创新效率差异与收敛性研究

Study on Efficiency Differences and Convergence of Electronic Information Manufacturing Industry in China

文章从技术创新投入、环境、产出三个层面,分析了我国电子信息制造业技术创新的现状,运用DEA模型和非参数Malmquist方法,对我国电子信息制造业技术创新效率从行业、地区两个维度,进行静态比较和动态测度,并分析了区域间技术创新效率的差异是否存在收敛性。实证结果表明:我国电子信息制造业技术创新效率总体不高,东部高于中部和西部,2001-2010年间,我国电子信息制造业的技术创新效率平均提高了22.4%,中部提高的幅度最大,总体上存在收敛趋势。最后,结合现状与实际问题,进一步探析了实证结果的启示。

From the perspectives of input,environment and output of technical innovation,this paper analyzed the status quo of technology innovation in Chinese electronic information manufacturing industry. Then by use of DEA model and non-paramet-ric Malmquist index methods,this paper made both static and dynamic measurement to technology innovation efficiency of elec-tronic information manufacturing industry including industry and region dimensions,and further tried to find out whether there was convergence or not between different regions. Empirical results showed that：the efficiency level of electronic information manufacturing industry in China is not high overally, where the eastern is higher than the central and western, and it in-creased by an average of 22.4%during 2001-2010 in which the centre improved best,and there existed the convergence trend. Finally,combing the status quo with practical problems,we further explored the insights from empirical results.
