The energy efficiency assessment of a mechanical manufacturing system is the system- atic evaluation about energy consumption status,energy consumption processes and energy efficiency of the system. As the premise of reducing the system＇s energy consumption and improving energy ef- ficiency, the assessment system has gradually been studied in the world. This paper firstly analyzed the characteristics of energy efficiency assessment for mechanical manufacturing system and, conse- quently, summarized four traits, namely the multiple-energy-sources feature and the multiple- layer architecture feature of the energy consumption status and the complicacy-variety feature and total life--cycle feature of the energy consuming processes and instantaneous energy efficiency. And then, based on the characteristics analysis, the current researches of the energy efficiency assessment for mechanical manufacturing system were analyzed, including the assessing contents and the energy efficiency indicators. Finally, the future trends of the energy efficiency assessment for mechanical manufacturing system were concluded. The trends can be detailed as the construction of the integrated index system and the development of the basic database for energy efficiency, the quota of the energy consumption of manufacturing products and tasks, the standardizations of the energy efficiency as- sessment, and the development of informationization ment and improvement, et al. platform for supporting energy efficiency assess
