Simulation of macroeconomic object performance based on ecological criterion

Complex analysis of regional ecology situation requires research of all regional system interconnections both with each other and with external environment. This work presents results of estimation of macroeconomic object stability corresponding to industrial complex of Samara region. Pro-posed analysis is based on research of marginal productivity of business-recourses usage. Mathematical models are represented that adequately describe the operation of complex productive-economic object based on ecological criterion. We produced analysis of the main business resource influence on system performance indicators by simulation methods. Control and management system is developed and proposed, it provides to predict of managerial decisions in the field of investment activity for regional ecological situation improving. We present approaches for decision making that improve ecological situation in the region.
