This paper investigates a multifactorial model, which allows defining an optimum level of banking regulation intensity based on the provision of a financial stability (at the macrolevel) and financial stability of banks (at the microlevel). An aggregated index of banking regulation intensity as well as an integrated index of financial stability of banks, which were the main factorial and resultative characteristic features during investigations, was formed for carrying-out of an empirical analysis. The optimum level of intensity of banking regulation has been suggested to define as the extremum of function of integrated index of financial stability of banks (determined by the method of the uniform optimality) on the relevant influencing factors (method of principal components).

The study is aimed to investigate the impact of banking regulation intensity on the efficiency of banks with different forms of capital ownership. To test the hypothesis about the different level of influence of banking regulation instruments on state, private and foreign banks, the GLS-modeling tool was used. The study sample includes data on the banks from six countries (Ukraine, Poland, Kazakhstan, Georgia, Estonia and Belarus) within the research period of 2001-2014. Empirical calculations indicate that there is no need to introduce differentiated regulatory regimes depending on the form of ownership and the origin of bank's capital, since there are no significant differences in the impact of different components of the regulatory mechanism on the banks of different ownership forms and different origins of capital. Particularly noteworthy is the formulation of a strategy for regulating stateowned banks, with slight differences in the effectiveness in the use of indicative and administrative instruments, while at the same time the importance of
