The article is devoted to the problems of creating an environment favorable for healthy and full life in the regions of Southern Siberia in accordance with the goals of national projects and the UN Sustainable Development Goals recognized by the Russian Federation. The article critically analyzes various ratings of Russian regions (ecological, ESG-ranking, urban environment quality index, “Green Patrol”, IQ of cities, etc.), their advantages and disadvantages. A new mechanism for comparing  Russian  regions  within  the  framework  of  the  national  project  is  considered,  and  the  results  of  its  testing  in  the South Siberian regions are given. The ways of joint solution of specific environmental and social tasks by government bodies, business and society are outlined, including through the activation of public participation in them (within the framework of “green  finance” by  issuing  special  bonded  regional  loans),  as  well  as  rethinking  the  migration  and  social  policy  of  the state, careful analysis and consideration of regional peculiarities.

The article is devoted to the analysis of cause-and-effect relationships in the territorial ecological and economic systems of Siberia, in which the technogenic load is as close as possible to or even goes beyond the ecological capacity of the respective territories. Among such territories, first of all, oil and gas producing regions of Western Siberia, Kuzbass (Kemerovo region), Norilsk industrial region, the territory of the Middle Yenisei — Angara and Lake Baikal are singled out. Environmental measures are proposed, the implementation of which could ensure the improvement of the ecological situation in these regions.

Scientific research of economic regions has been going on for more than one century, but there is still no complete clarity about the essence of this phenomenon. The purpose of the article is to identify the key features of an economic region and formulate its definition on this basis. When writing the article, a retrospective method was used. A model of the structure of an economic region is proposed, which reflects its cardinal transformation as it evolves. It is argued that at the highest level of development, the region becomes a mono-product and is part of a multi-product macroregion. Four phases of the development of the region are identified, each of which corresponds to its own list of features. For this reason, it is stated that an economic region cannot have a fixed set of characteristics: the region is continuously changing under the influence of both external and internal factors. At the same time, the nature of its changes can be both evolutionary and regression. It is assumed that the specialization industry of the region as part of the macroregion should have the maximum return on assets compared to other national industries. In this regard, the analysis of the profitability of the assets of industries from a random sample of countries was carried out, the leading industries were identified and, based on this, the structure of a conditional macroregion  is  shown.  Definitions  of  an  economic  region  and  a  macroregion  are  proposed.  According  to  the  author,  the reasons for the emergence of an economic region are of an intrasocial nature. The article substantiates the role of social pressure in expanding the borders of the region.

The article considers the application of an effective method for the analysis of nonlinear systems — the theory of bifurcations. The classical problem of fixed capital growth under the influence of investments is analyzed, where the volume of investments depends on the already existing capital and the economic number that assesses the level of economic development. The dependence of fixed capital on the economic number is considered in a state of equilibrium. When out of equilibrium, various types of bifurcations arise. The Taylor formula is used to find a solution for close values to the equilibrium point of the economic system. As a result, we obtain a new state of equilibrium that does not lead to a bifurcation of fixed assets. Analytical  formulas are given for determining bifurcation points and boundary states. The state of the economies of three EU countries in the period 2007—2015 is considered, and an analysis is made of the occurrence of bifurcations of fixed assets.  The  conditions  for  the  emergence  of  two  possible  solutions  and  the  appearance  of  a  supercritical  bifurcation  in  the economies of these countries are determined. A system of two ordinary differential equations is considered that describes the growth of fixed assets and labor resources depending on the economic number and mutual influence on each other. Analytical  formulas  are  derived  to  determine  the  moments  of  occurrence  of  bifurcations.  This  system  of  equations  has  Hopf type bifurcations. As a rule, bifurcations are associated with the appearance or disappearance of stationary solutions, and with the Hopf bifurcation, periodic regimes arise — a stable focus or a limit cycle. With an increase in the economic number, the focus loses stability and a limit cycle appears, the radius of which varies as the square root of the economic number.

The article is devoted to the issues of researching potential consumers and applying the segmentation  method based on the “work to be done by the product”. This  method proposes to focus  not on portraits of potential consumers, but on the problems they want to eliminate and how they do it. The method is based on the assumption that to satisfy a  need and solve a problem, a consumer  must buy or “hire” a particular product that can do the necessary work. The work can be done by different products, and it is also important to consider the context  in  which  the  problem  is  immersed.  The  method  allows  us  to  understand  the  needs  and  motivations of consumers.  With  its  help,  the  target  audience  can  be  structured  more  precisely  and  target  segments  can  be selected. This, in turn, leads to the creation of more appropriate products for potential consumers from different segments.

This article is devoted to the results of the approbation of the author's methodology for analyzing the strategies of socio-economic  development  of  the  subjects  of  the  Russian  Federation,  taking  into  account  the  innovative  component,  and the presentation of an integrative  mechanism  for taking into account  the effects of concentration in strategic planning. The types of regions are identified by the level of innovative development, taking into account the effects of concentration and by taking into account the innovative component in the strategies of socio-economic development of the subjects of the Russian Federation. The obtained research results can be used to update regional socio-economic development strategies.

The  article  describes  the  developed  tool  of  innovation environment  management  with  the  help  of  cooperation. The tool allows assessing the level of development of the innovation environment of regions in order to determine their features and potential to ensure technological leadership in the markets of the future. The results of approbation of the tool in the Tomsk region are presented. Recommendations on managing the  innovation environment  with the help of cooperation and increasing the level of development of the region's innovation environment taking into account its technological backlog and innovation orientation are formulated.

Most of the small towns of Russia, which form the basis of rural areas of the country. is in a state of depression and depopulation all post-Soviet period. The reason for this is a set of problems, first of all the imperfection of federal legislation regulating the functioning of local self-government bodies. Its external consequences is a chronic shortage of financial resources for the development of small towns and surrounding rural areas, as well as a low professional level of management in local authorities. The analysis carried out in the work shows that there are a number of reserves for increasing the effectiveness of local  self-government, which can increase the financial security of local  communities, and weaken the effect  of depressive factors, and in some cases, perhaps, provide conditions for infrastructure development. even in the existing conditions.
