Abstract:Based on the relevant data of intelligent manufacturing listed enterprises from 2013 to 2017. firstly,the technological innovation efficiency of listed companies is measured and analyzed by using DEA cross-efficiency model. Secondly, the factors that affect the efficiency of technological innovation and its degree are analyzed by using the Tobit regression model. The empirical results show that the technological innovation efficiency gap between intelligent manufacturing enterprises is large and on the low level as a whole. The annual average efficiency is concentrated between 0.35 and 0.4, but there is an upward trend over time. It is found that enterprise repayment ability,enterprise profit ability,enterprise operation ability,enterprise size and the market scale of the core industry in the field of intelligent manufacturing have a positive effect on the efficiency of technological innovation. Among them, the operation ability of the enterprise has a significant impact, while the size of the enterprise has a small impact. Finally, three suggestions are put forward to improve the technological innovation efficiency of intelligent manufacturing enterprises.
