Definition of industrial enterprises development conditions and new approaches to resources using

The article presents an analysis of the conditions required to provide the industrial sustainable development in the digital transformations. A study has been carried out that determines the complementary assets role in modelling the enterprises development management processes operating in the context of ecosystem interactions in order to determine the properties of complementary interactions that contribute to the further value formation as a result of controlled changes in interactions by activity type or by product type. It is proposed to establish interactions by economic activity types presented in the Russian Classification of Economic Activities, which will allow us to determine the maximum possible profitability as a condition of complementarity from the main activity type and additional incoming types. The complementarity signs, which make it possible to achieve the required development and sustainability level in the ecosystem, have been determined

Formation of the investment portfolio on the basis of adaptive-discrete model, considering globalization effects

The article implements the idea of usage of universal properties of an adaptive regression modeling procedure in the processes of making investment solutions with predictor optimality. The necessity of using of universal properties is that the same value in the stock market can be predicted on the basis of inertial changes, and on the basis of discrete, discontinuou
