This paper aims to analyse the potential of "smart city" management facilitated through the integration of economic-legal and technological tools.Based on an expert survey, measures are identified to integrate economic-legal and technological tools in the concept of "smart city" management, and a model of "smart city" management is developed. Foreign practices of "smart city" management are reviewed in the context of raising environmental and ecosystem sustainability. It is shown that "smart city" management is contingent upon the implementation of specific measures to integrate economic-legal and technological tools, as well as on the development of a model of "smart city" management and adoption of existing foreign practices in raising environmental and ecosystem sustainability.
