Industrial ecology, eco-efficiency, eco-design, X multiple of revolution are theoretical basis for sustainable development. Among these, eco-efficiency is the most popular method for quantitative analysis. The concept of eco-efficiency was firstly put forward in the academic by Schaltegger and Sturn in the year 1990. Being promoted greatly by the World Business Council for Sustainable, eco-efficiency has obtained great attention in sustainable development research. Claude Fussler firstly introduced the concept of eco-efficiency to China in 1995. There are many achievements in the researches of eco-efficiency in china in recent ten years. Different accounting methods of eco-efficiency in different researching fields were developed, especially in the researches on circular economy in different scales of urban, regional and national level. In this paper, eco-efficiency counting methods and applications in different scales have been sum up based on the review of relevant literature in recent ten years. The accounting methods of eco-efficiency were divided into three categories: (1) Economic/environmental single ratio method. Sometimes, the total production of the product or service, total sales and the total net sales were used to stand for the economic dimension. Resources consumptions, carbon dioxide emissions or other environmental impacts were used to present the environmental dimension. (2) Indicator system method was consisted by indicators which independent from each other but stand for each sections of the research subject. The indicator system method is suit for analyzing the complex systems which contains social, economic and natural subsystems. (3) Modeling method. Data envelopment analysis method is the main method, and other productivity models have been used for eco-efficiency analysis. Then, eco-efficiency could be applied on different scales, such as plant, industry, regional and etc. According to the summarize of current researches, we found that: (1) Researches on eco-efficiency have shifted from simple evaluation to driving mechanism exploring shown in international literatures, but domestic researches still remain in the simple evaluation level. (2) Modeling and methods of eco-efficiency exist in the area of accounting, finance and productivity have been brought to modify and correct the economic/ecological ratio model, while domestic researches focus on building a multi-index system of eco-efficiency, and apply the productivity models for assessment. (3) In the area of eco-efficiency application, international researches showed interests on industrial system and its production system, and applied eco-efficiency method to eco-design and product development. Comparatively, domestic researches mainly focus on the assessment of ecological parks, urban and regional areas, but very few researches in the scale of industrial scale. (4) International researches of eco-efficiency were associated with global ecological issues, such as global warming, biodiversity, food security, while domestic researches focused on analyzing pollutants and wastes. (5) Current studies didn't explain the roots of ecological and environmental crisis, and the social dimensions were usually not taking into consideration. Finally, the article point out, domestic government should spread the notion of eco-efficiency, propel the researches and applications both in micro and large scale; Improve the eco-efficiency accounting methodology with theories and methods of economy, management, accounting and other disciplines; Use the full array polygon graphical methods to reflect the different aspects of the social-economic-natural complex ecological system.
