Innovations are a continuous process so the issues related to life cycle management of a retail enterprise are relevant. Effective management of enterprise life cycle allows reducing risks and decreasing the degree of uncertainty of its innovation activity. To describe the innovations life cycle the authors used Verhulst equation according to which the logistic function determines the innovations life cycle as a sigmoid – s-shaped curve. The method suggested by the authors determines the correlation interaction between determination of the moment when the innovation is introduced into retail enterprise activity and the innovation ageing period. The article substantiates that it is reasonable to use sales volume as a factor of effect from introduction of innovation in retail enterprise. Such factors as profit, efficiency, consumer traffic or mean receipt sum can be used as well. The novelty of the author approach is that it contains the interaction between life cycle stages of retail network and innovation introduction moments which enables to estimate the effectiveness of innovations in the enterprise. The information provided by such analysis will enable the management to elaborate a competent and effective development strategy of the company and in such a way increase its competitiveness.

The paper is devoted to topical issues of urban planning in relation to megacities. We consider this issue taking into account the limitations of natural, communal, and social resources. The problem is especially acute for the overwhelming majority of the state capitals, as well as cities with historical heritage that are of great interest due to the rapid development of tourism and the high mobility of the population in the world. The authors formalize the problem of determining the optimal ratio of the volume of urban buildings intended for non-residents to the total housing stock. We conduct economic calculations to determine the quantitative indicators that can be used as the basis for administrative measures aimed at limiting the flow of people arriving with the intention of temporarily deploying in megacities.

The present-day development of the Russian Federation is mostly shaped by the innovative development capacity of the national economy. Industry forms the core of such development. The paper presents the study of the current state of the innovative development in industry being the source of the basic innovations, as well as identifies the limitation factors. The authors have found out that low innovative activity of the industrial enterprises holds back the implementation of innovations in the related sectors, for instance, trade.
