Study on efficiency of China's power equipment manufacturing industry based on total factor productivity index

Abstract

This article, from the reality of the electric power industry development, using DEA method constructs the power equipment manufacturing industry production efficiency index, then, calculates using software. From the calculation, the results show that the efficiency changes frequently exists, and the new energy efficiency of the enterprise is relatively low. Finally, Suggestions are proposed according to the problems. © Springer-Verlag 2012.
