Abstract: Expected ecological efficiency has been described as the minimum efficiency requirement by ecological resources owners for such resourcesuse in companies. Based on that， green EVA was analyzed to fit the necessity of ecological resources owners for expected ecological efficiency. Then， green EVA indicators were established in accordance with expected ecological efficiency to elaborate the opportunity cost of green EVA for ecological resources owners and modify the impact of varied enterprises' environment protection investments on EVA. In addition， the features of how companies make breakthrough in the value creativity for scarce ecological resources were weighed and a green EVA calculation method was given. By calculating the green EVA of Baosteel in 2014 and comparing it with the traditional EVA， the operability and applicability of green EVA indicators were verified. Moreover， it was suggested that green EVA assessment should be put into trial use in SOEs with high energy consumption and pollution.

Key words: green EVA, eco-efficiency, environmental protection investment
