摘要：The concept of sustainable development (SD), formulated 30 years ago, was, is and will be one of the most pressing problems of human development constantly solved. The fundamental question of this phenomenon is quantification of the condition. There is no unified approach yet, despite numerous studies of all kinds. All the proposed ways are not evaluating sustainable development but individual components (economic, social, environmental) or socio-economic systems (SES) development. In order to achieve an adequate quantification of SES SD, two aspects of this process should be distinguished: quantitative and qualitative. The quantitative side is the order (dynamics) of the development of the socioeconomic system, which can be expressed in the degree and intensity of development. The qualitative side is the coherence of the development of SES as a complex system. Socio-economic systems belong to large, complex, whose essential characteristic is the structure, the basis of their stability. It is the harmony of development that reflects the coherence between structural changes in development and internal development processes. The complex quantification of SES in sustainable sustainable development integrates both sides of this process - quantitative and qualitative, ie sustainable and harmony.
