Method for regularity control of mathematical models of economy in system of modelling support ECOMOD is described. Method includes the procedure for finding maximal subgroup of group of scaling transformations, that preserves the relations of the model. It besides takes into acount some additional dimensional requirements, that system of relations in itself does not contain. These substantial requirements can be formalized so that it is possible to draw a conclusion about the regularity of the model from the correspondence between existing maximal subgroup and additional requirements. Also the method for finding automodel solutions is presented, that exploits the same procedure. It is based on the system of measurement units, that contains dimensions of material and financial assets along with dimension of time and all dimensions derived from them. Some independent growth rate is then assigned to each of the base dimensions, and growth rates of all dynamic variables are expressed using their dimensions.
