中国区域大中型工业企业技术创新效率变动的实证研究

The Dynamic Analysis on Technological Innovation Efficiency of Regional Big Medium-sized Industrial Enterprises in China

以2001-2008年中国30个省级区域大中型工业企业面板数据为样本,利用非参数Malmquist指数方法实证测评了30个区域大中型工业企业在2001-2008年间技术创新效率的动态变化,考察了大中型工业企业省际技术创新效率的变化来源与差异。主要结论有:2001-2008年间,中国大中型工业企业技术创新效率出现了一定的下滑,主要原因是技术效率的下降,并且技术效率的恶化是纯技术效率和规模效率共同下降的结果;大中型工业企业技术创新效率的增长机制存在一定程度上的不稳定,其技术创新效率变化指数具有明显的波动特征。

Taking panel data of Chinese 30 provincial regions＇ big medium-sized industrial enterprises from 2001 to.2008 as sample, based on Malmquist index and DEA model, this paper evaluates the dynamic changes in technological innovation efficiency of them, and examines the source of changes and differences in technological innovation efficiency of inter-provincial big medium-sized industrial enterprises. The results show that： there is a decline of the technological innovation efficiency of those enterprises, mainly dues to a decline in technical efficiency, which is the result of the drop of pure technological efficiency and scale efficiency at the same time; the growth mechanism of technological innovation efficiency is instable to certain degree, and there is obvious fluctuation of its technological innovation efficiency variation index.
