传统的效率评价方法视技术转移系统为一个“黑箱”，忽略对系统内部运作机理的分析。本文针对传统效率分析方法的不足，打开“黑箱”将产学研技术转移系统内部结构解析为技术创新和产业价值创造前后联结的两个阶段，并运用两阶段DEA方法对我国30个省区2010-2013年的产学研技术转移效率进行测算。测算结果表明我国产学研总体技术转移效率偏低，技术创新阶段是制约总体技术转移效率提升的瓶颈；各个省区技术转移优势环节不同，应该搭建全国统一的技术转移服务平台以充分发挥各省区各自优势弥补其薄弱环节。

The traditional technical efficiency measurement regards the technology transfer system as a "black box", ignoring the analysis of the internal operation mechanism. This paper opens the "black box" and divides the industry-university-research institute (IUR) technology transfer procedure into two relational sub-processes including technological innovation and industrial value creation. Then this paper evaluates the IUR technology transfer efficiency of China's 30 provinces from 2010-2013, applying the tow-stage DEA model. The empirical results show that: the overall efficiency is low, and the technical innovation stage is the bottleneck of the overall technology transfer efficiency; the advantages in technology transfer of the different provinces and regions are various, so a unified platform should be built to full use of the respective advantages of the provinces and regions and make up for the weak sub.
