基于共享投入两阶段DEA模型的中国省际高技术产业研发创新效率评价研究

The research on the R&D innovation efficiency evaluation of China’s provincial high-tech industry based on two-stage DEA model with shared inputs

摘要:

基于中国高技术产业技术开发和成果转化两阶段视角，考虑共享资源在两个子系统间的分配结构，构建包含共享投入在内的中国高技术产业研发创新效率评价指标体系，运用共享投入两阶段DEA模型对我国29个省份2010—2014年的研发创新效率进行测算。研究结果表明：我国高技术产业综合效率水平不高，东部地区高技术产业效率高于西部和中部地区，研发创新综合效率基本呈现倒“U”型变化特征，省际间高技术产业效率差距较大；中国高技术产业技术开发效率显著高于成果转化效率，高技术产业研发创新效率利用模式属于“高技术开发，高成果转化”型的省份仅占样本总数的27.5%，且主要来自东部地区。最后，根据中国高技术产业实际情况，给出了一些政策建议。

Abstract:

This paper, considering “the allocation information of shared resources in the two sub-systems”, constructs an evaluation index system of the R&D innovation efficiency for China’s high-tech industry from the two-stage perspective of technological development and achievement transformation sub-stage. It employs shared input two-stage DEA model to evaluate the R&D innovation efficiency of 29 provinces in China during 2008-2014. The results show that the overall efficiency of China high-tech industry R&D innovation is not high, and the efficiency of the eastern area is higher than other regions. There are significant differences in all provinces, and the overall efficiency of China high-tech industry R&D innovation shows an inverse U-shape trend. The technological development efficiency is higher than achievement transformation efficiency significantly, and 27.5% of the R&D innovation efficiency utilization model across the country belongs to “high technological development, high achievement transformation” type. Finally, according to the actual situation of high technology industry in China, some policy suggestions are given.
