Implementation of smart-city tools as a response to challenges in socio-humanitarian field in Ukrainian metropolises

The article investigates theoretical foundations of public management in the socio-humanitarian sphere of metropolises based on the smart city concept. It defines the essence of the concept of "public management in the sociohumanitarian sphere" in a metropolis, which should be considered as a multi-branch and inter-sectoral complex formed with the involvement of local authorities, business partners, the public, and citizens, and aims to create, maintain, and develop a favorable safe environment as a unified system of life and livelihood of the city based on the balanced development of the main sectors of the economy and socio-humanitarian sphere. The abstract also defines criteria for the efficiency of public management in the socio-humanitarian sphere within a modern metropolis, which include integrity, sustainability, and security of the subjects in obtaining a positive effect of solving socio-humanitarian issues within a metropolis. The main mechanism of public administration in a metropolis is establishment of interaction in the triad "power - business - community" and coordination of their interests (business - "here and now", community - "the welfare of our children", the state - "the welfare of citizens"). It is confirmed that the digitalization of public administration contributes to strengthening control over the use of all types of resources for the optimal development of the sociohumanitarian sphere of Ukrainian cities.
