Waste landfill plant and waste disposal plant efficiencies in China

As resident awareness of environmental issues has grown, waste disposal has become an important part of urban environmental governance. Most previous research from developed countries that has sought to evaluate the technical, energy and environmental efficiencies of urban waste disposal have employed DEA. However, as there has been little research into China's waste disposal efficiencies, this study used a dynamic DDF (directional distance function) DEA (Data Envelopment Analysis) to analyze the total waste disposal efficiencies in 23 provinces in China from 2012 to 2016, from which it was found that nine had excellent efficiencies of 1, but significant efficiency improvements were needed in 14 others.
