Intelligent Manufacturing Enterprises' Efficiency Evaluation of Technological Innovation: Research Based on DEA

摘要

In this paper, we utilize Chinese intelligent manufacturing enterprises' panel data during 2010-2013 to evaluate technology innovation efficiency. Studies have shown that the average technology innovation efficiency of intelligent manufacturing industry is in the rising stage, but the overall efficiency is still relatively low. Differences in technology innovation efficiency in various fields of intelligent manufacturing industry is relatively obvious. The development of CNC machine tool industry is relatively mature, while the technical development of intelligent manufacturing complete sets of equipment area is still in its infancy.
