A commune is a system in which various types of relationships between individuals and groups take place. It is bound by law to provide specific services and tasks. This requires the use of certain economic, infrastructure and financial resources. Finances are therefore the basis for the implementation of public tasks and determine the conditions for local economic development. The aim of the article is to analyse the spatial disproportions of communes' development in relation to their financial situation with the use of a synthetic measure (TOPSIS) in 2012, 2014, 2017. As part of the research, data from the Regional Data Bank of the Central Statistical Office and the regional accounting office were used, which allowed to build a synthetic measure of development and financial situation. The financial situation determines the scope and level of public services and tasks performed by rural communes. It is also one of the elements of creating opportunities or barriers to the competitiveness of rural communes.

The financial situation determines the scope and level of public services and tasks performed by rural communes. It is also one of the elements of creating opportunities or barriers to the competitiveness of rural communes. The value of the development measure fluctuated in 2012 from 0.38 to 0.54; in 2017 from 0.37 to 0.63. The best units (Strawczyn, Morawica, Sitkowka-Nowiny) in the studied area are characterized by a high position within the financial situation and good industrial function, which is supported by a well-developed infrastructure and social. These are units for which the agricultural function disappears and the industrial function significantly develops.
