作者通过构建以研发资本存量作为创新投入变量建立省级区域技术创新指标体系,运用数据包络分析方法(DEA)对我国30个省级区域2004-2015年的技术创新效率进行测算与比较分析。研究结果表明,考虑研发资本存量后,可以显著考察到前期的研发资本投入对当期的技术创新活动的影响。作者又以湖北省为例进行技术创新效率分析,发现湖北省技术创新效率不高的主要原因为：纯技术效率低、创新投入资源未充分利用、创新产出不足。

The impact of the accumulation of innovation input on technological innovation has been recognized by most scholars. But now there are few scholars set up the evaluation index system with variables of the innovation accumulation. Based on the R D capital stock as the innovation input variable, this paper establishes the provincial regional technological innovation index system, and uses the data envelopment analysis method to measure and compare the technological innovation efficiency of the 30 provincial-level regions in China from 2004 to 2015. The results show that, considering the R D capital stock, we can significantly examine the impact of the previous R D capital investment on the current technological innovation activities. In this paper, taking Hubei Province as an example to analyze the efficiency of technological innovation, it is found that the main reasons for the inefficiency of technological innovation in Hubei Province are: low efficiency of pure technology, insufficient utilization of innovation resources and insufficient innovation output.
