Ecological efficiency evaluation of marine ranching based on the Super-SBM model: A case study of Shandong

To investigate the efficiency level of marine ranching in the process of ecological management and the balance between the economy and ecology, we proposed a comprehensive index system based on the entropy weight method and measured the Marine Ranching Ecological Efficiency (MREE) of 18 marine ranch...
