Based on the perspective of technology gap, the analysis and comparison have been made on the regional differences of the listed steel corporations and the technological gaps in China from 2009 to 2018 by the method of meta-frontier and DEA model.In order to find out the root cause of inefficiency,we decompose the innovative inefficiency of steel listed companies in various regions by the two dimensions of “production technology gap” and “enterprise management level”.The research shows that:innovation of steel enterprises overall efficiency is low, with the efficiency decreasing along the eastern, central and western regions.Pure technical efficiency and scale efficiency are both not high.The meta-frontier efficiency is less than the frontier efficiency.The technology gap between eastern steel enterprises and midwest ones are located in0.05~0.3, and there is a reduced trend in recent years.The innovation efficiency loss of steel listed companies from different regions is different.In the eastern region the low management level is the bottleneck factor causing the loss of innovation efficiency of steel enterprises.The efficiency loss of steel companies in the central and western regions is subject to the combined effects of production technology gaps and management inefficiencies.
