Introduction. Public-private partnership (PPP) is considered as the interaction of the state and business structures - subjects of economic activity of Ukraine and foreign subjects of economic activity (also subjects of economic activity of Ukraine with foreign countries), which is one of the conditions for attracting the necessary investment resources, increasing innovative activity in the national economy, development of economic and social infrastructure, solving economic, social and environmental problems, etc. Purpose. Taking into account the trends in the number of PPP projects in foreign economic activity in Ukraine and the world, their financing, areas of implementation, geographical localization, the article should provide a quantitative assessment of data characterizing the state and level of implementation of PPP projects in foreign economic activity, obtained after performing mathematical operations. Method (methodology). The article uses theoretical generalization, analysis, synthesis, statistical methods of data processing, etc. This ensured the analysis of literary sources, the formation of a system of indicators intended for assessing the state of PPPs in foreign economic activity and its practical approval. Results. The article recommends a system of indicators, which includes: the growth rate of the number of PPP projects in foreign economic activity, the average base (chain) growth rate of the number of PPP projects in foreign economic activity, the growth rate of the number of PPP projects in foreign economic activity, the average base (chain) rate increase in the number of PPP projects in foreign economic activity, the level of implementation of PPP projects in foreign economic activity, etc. For each of the recommended indicators, the method of calculation is indicated depending on the selected strategy of interaction of PPP subjects in foreign economic activity. With their use, an assessment of PPP in foreign economic activity was carried out based on the study of PPP projects implemented by Davydivska OTG. Based on the results of the assessment, conclusions were drawn regarding the trend in the implementation of PPP projects in the foreign economic activity of Davydivska OTG.

The current model of resource management mainly contributes to mass short-term consumption, which creates an unstable and extremely critical situation on the planet. Going beyond the traditional industrial model of Take-Make-Waste, the circular economy aims to reduce waste (and therefore minimize costs) and to redefine sustainable development. This entails a gradual separation of economic activity from the consumption of scarce resources and the removal of waste from the system. In order to foreground the principles of a circular economy in Ukraine, this study analyzes its benefits based on the relevant experience of the EU. The paper also presents the results of research and content analysis on the situation of waste management in Ukraine and compares the trends using key indicators. The core of the paper is developing a conceptual model of making and coordinating management decisions on the implementation of business projects in the context of a circular economy in Ukraine. A multifactor model (the Farrar–Glauber method was further developed) has been built by identification of the main factors, i.e., the volume of generated waste from economic activity per unit of GDP at constant prices, emissions of pollutants, and capital investments for the protection of the environment. Factor coefficients indicate how many units will change the resultant trait Y, measured in thousand tonnes, if one of them changes by 1 (each in units of measure). It means that if the volume of waste generated from economic activity per unit of GDP at constant 2011 purchasing power parity (PPP) prices decreases by 1 kg/$1000, waste management of I–IV classes will be reduced by 952,737 thousand tonnes. The approbated model can be used to analyze the situation with recycling in the EU countries, considering the amount of capital investment in environmental protection.

The pace and scale of the digitalization of today’s global information society open up new opportunities for business. At the same time, they set new challenges for business owners and managers in the field of marketing. Given this fact, the purpose of the study was to present the impact of digitalization on the marketing activity of the enterprise in the field of services by promoting the use of online sales via electronic distribution channels, social networks, and mobile applications. A comparative system of estimating the parameters of the influence of digitalization on the marketing activity of the enterprise was proposed as a confirmation of this impact. Based on the developed “tree of goals,” the dynamics of the digitalization of services were projected and the prospects of development of this sphere of activity were outlined. For testing the proposed methodology, the railway passenger transportation company (JSC “Ukrzaliznytsia”) was chosen as the object of the research. Research methods used in the study include: (1) statistical; (2) SWOT analysis; (3) systematization, comparative, and structural-dynamic analysis; and (4) an expert survey. As a result of revealing the impact of individual elements of digitalization on the level of marketing activity, the number of recommendations regarding the development of digitalization of electronic ticket sales services and their accounting for enterprises dealing with railway passenger transportation were proposed.

The object of research is the formation of blocks of the categorical apparatus of the construction industry to determine the strategic guidelines for development of construction. The need for criticality to the variable parameters of the construction complex requires the effectiveness obtained by mathematizing and modeling the formalized data. In the course of the research, a comprehensive approach to the analysis of the conceptual apparatus is used, which determines the main directions for strategic development of construction in general. The need for an integrated approach is confirmed by the experience accumulated by science and practice. The formed modular base of the indicative space of the conceptual-categorical apparatus of construction makes it possible to focus further research in direction of stable development. Thanks to the formed blocks of the indicative space, the combined tools and tools for designing, developing and improving complex analysis in resource unity allow to evaluate the feasibility of construction activities, that is, they have the property of representability. The direction of actions through goals, functions, principles, i. e. the procedural component coordinates the sequence and interrelation of the construction stages.

The analysis of the publication activity of domestic universities according to SciVerse Scopus scientometric database is conducted and its dependence on the effectiveness of the motivation systems in these universities is established. The necessity of rating the publication activity of scientific and scientific-pedagogical workers of higher educational institutions as effective ways of ensuring the competitiveness of universities, providing and improving the presence in international and domestic universities rankings is substantiated. The positive experience of managing the publication activity on the example of the Taras Shevchenko National University of Kyiv and the "Lviv Polytechnic" National University is shown. The methodology for the formation of the rating of the SSPS publication activity by the indicator is developed, which is calculated as the average number of scientific publications (monographs, articles, conference proceedings) for a certain period. It is shown that the indicators of publication activity and citation indexes are not the only and final criteria for assessing scientific results, but only an instrument for supporting decision-making by experts. Measures are developed to strengthen the publication activity.
