Analysis on input-output efficiency of renewable resources industry in Hubei Based on DEA-Malmquist model

Abstract

Recycling of renewable resources is an important way to promote economic green, cycle and low-carbon development, and to build a resource-saving and environment-friendly society. In order to improve the input-output efficiency of renewable resources industry in Hubei Province and realize the effective allocation and scale benefit of renewable resources, this paper selects five input-output indicators, including fixed assets stock, annual average number of employees, number of enterprises, total industrial output value and total profit volume of discarded resources comprehensive utilization industry. Then we use DEA-Malmquist index model to calculate the input-output efficiency of the renewable resources industry in Hubei province from 2009 to 2016. According to the result, we explore the changing trend of production efficiency and the reasons of its change. The conclusion can provide reference for relevant departments to propose strategies for improving efficiency and promoting industrial development.
