Khomenko Y. Investment management: evaluation of economic systems stability

Research object: meso- and microlevel economic objects. Research purpose: development of conception of investment resource optimal allocation. Methods of research: system and technical analysis, mathematical statistics, economic and mathematical modelling, dynamic approach, co-relation and regression analysis, range statistics and Speerman's and Candell's range co-relation coefficients, empiric approach. Results: modified three-level model of governmental control of foreign investment is projected; recomendations for examination of basic resulting characteristics of investment process subjects based on long-term dynamic approach is suggested; peculiarities of mesolevel systems functioning are determined; integral index of functioning efficiency of regional econmical system is proposed; sample dynamic mathematical model of stable functioning of regional economical system is developed; methodological recomendations for regional project creation with respect to branch aspect are given;priority coefficien t of invetment market directions by national economy branches is suugested and proved; method of proved estimation of enterprize's financial stability for microlevel capital-attainer characteristics is suggested; enterprize rating by productive and financial coefficients is created. Novelty: modified three-level model of governmental control of foreign investment is projected, it specifies the control mechanism creation, which is specific only for transformation period, and it proves complex and purposefful approach to regions from the point of view of stability estimation of their economical systems; complexmethod of economical system stability estimation of mesolevel, based on rang co-relation methods and in behalf of this gives the opportunity to combine economic indexes of different nature to general index; sample dynamic mathematical model of functioning mode of regional economical system is developed, it allow to perform a transition from expert estimations to scientificly proved standarts while invest ment rating is analisied and determined; branch investment direction market priority coefficient is suggested, it generalize basic branch functioning characteristics: capitel investment dynamics, capital circulation rate and investment efficiency; financial stability estimation technique based on choice of coefficients from native and foreign practice, adapted to the Ukrainean accounting system, is developed, it allow to determine the investment rating of the enterprize. Field of use: regional.
