An Empirical Analysis of Shandong Power Grid Operational Efficiency Based on DEA-Malmquist

Abstract

This article intends to use China State Grid Corp's business performance evaluation system to study the Shandong Electric Power Group Corp's power grid operation efficiency. And through analyzing the operational efficiency of each decision unit by DEA, we analyze the adjustment direction of the input and output on the angle of horizontal, vertical and internal analysis, find the investment shortage, and put forward some improvement measures. From the changes of the input and output efficiency in the last 15 years, the changing trends of the total factor productivities is found, and the successful experience of the high efficiency is obtained with the specific background.
