Regional economics consists of economic agents which are exchanging transactions and combine into subsystems. The relationships between agents can be illustrate using graph theory. One of the most suitable ways to describe method the ways of interactions and managing social systems is model management scheme. The main goal of the paper is developing structure and model of local economic subsystems managing. In the research process the scheme of model management of social subsystems on the municipality territory was formulated and the functions of its elements were described. An algorithm of local economic subsystems managing was presented, which allows processing bank transactions and searching closed subsystems which are consists of economic agents. It also allows modeling of key indicator changing (number of agent connections) through three strategies. The scheme of model management and algorithm were applied on the municipal territory with population of 59 thousand peoples. Bank transactions between organizations for 1 month in 4 bank branches is the research base. The 17 closed subsystems were found and network effect in the management of a key indicator (number of agent connections) presence was proved.
