This book helps to solve the problem of substantial waste and inefficiency in port production by analyzing operational efficiency at more than 30 Chinese and Korean leading container ports using three types of DEA model. In addition it offers a returns-to-scale analysis, which is particularly useful for port managers or policy makers deciding on the scale of production. The results provide port managers and relevant scholars with insights into resource allocation and operating performance optimization. This book was supported by the National Science and Technology Academic Publications Fund of China in 2015.
