The Empirical Research of Energy Utilization Efficiency in Industrial Sectors Based on DEA-Malmquist

摘要

This study selected Sichuan Province of China's energy production and consumption province as the regional research object.It studied energy utilization efficiency in industrial sectors from output of energy consumption,energy utilization technical efficiency,pure technical efficiency,and change index of energy utilization efficiency by the data of energy consumption and GDP.The output of energy consumption and energy utilization efficiency were big difference in industrial sectors.It provided the basis of taking different measures according to the different characteristic in industrial sectors while reducing energy consumption and energy conservation.
