Abstract
With the development of the times,large state-owned enterprises put forward a major strategic development layout, this paper takes the technological research and development in the strategic layout as an entry point, and proposes a set of index system to measure the technological innovation efficiency of the sample electric power enterprises. In this paper, the three-stage DEA method is used to evaluate the efficiency, and the research results show that: the enterprise's establishment years, gearing ratio, government subsidies and gross regional product all positively affect the redundancy of R & D inputs, and the impact of total assets is not significant, and after removing environmental noise and random interference terms, the Pure technical efficiency of sample enterprises is improved and scale efficiency is decreased, after adjustment, the scale reward of each enterprise reaches incremental or optimal scale status during the sample period.
