Eco-efficiency indicators in new technological development is an important aspect but it has little been mentioned in documentations on technology management in the country and abroad. Based on qualitative analysis of the technological development process, this article presents basic features of the use of eco-efficiency indicators in the process of technology development in three different stages: First, planning stage of a technology; Second, the stage before the development of technology; and Third, stage of technology transfer. The goal of this study is to provide some proposals for the use of eco-efficiency indicators in the process of technological development, as well as in the appraisal of technology development projects. Keywords: Eco-efficiency indicators; Technological development; Industrialization, Modernization; Sustainable development. Code: 13090301 Introduction Technological development implies the development of technical skills, machinery and equipment which constitute a basic element for promoting innovation in production. This makes the technology enter the market with products or services that it generates. However, besides the necessity of technological innovation promotion, limited use of natural resources brings a lot of challenges to the process of technological innovation. In addition, by direct observation, environmental pollution mainly comes from manufacturing processes. In the eyes of scientists, technology is the root cause and also the solution of environmental problems .
