Justification options taxation of small businesses in the region

This article analyses the operation of small businesses at the regional level under different tax systems with the help of complex simulation models. The features of simulation models for small businesses in the region. Complex simulation models analysing the operation of small businesses can not only judge the effectiveness of a tax system, but also to make a choice in favour of one of them for a particular small enterprises in the region. Profit distribution process reasonably small enterprise and the values of the relevant parameters of simulation model; in this technique was developed implementing imitation - optimization campaign to modelling of small businesses. Shows the principal features of simulation models of small firms, consisting in accounting factors differentiated demand substitutability of labour resources in multidisciplinary productions diversification activities on multi- enterprises; developed a schematic diagram calculations using optimization models (in the case of multi- enterprise).
