Recent joint report by World Bank Group and development research center of the State Council of China pointed out the importance of sustainable development of infrastructure in China. However, the most recent report by Natural Research Defense Council (Oct 0214) indicated that only a few port cities in China paid attention to the air pollution from ship and port activities. This study reports the finding of assessing energy efficiency of port operations in China based on the data from public domains by using the combination of Data Envelopment Analysis (DEA) and Panel Data Estimation (PDE). This study also exams the gap between the proposed green port evaluation index and actual guideline of port operations by local government. The aim of this study is to report the effectiveness of sustainable development policy and highlight the workable plans on improving energy efficiency with financial success.
