Motivation: We note significant problems of developing countries, including Ukraine, with the adaptation of organizational and economic mechanisms of the construction industry to increase impact of digital technologies on their economic systems and construction sectors. Novelty: The scientific novelty is a set of management activities for the adaptation of organizational and economic mechanisms of Ukrainian construction companies to the development of digital technologies. Methodology and Methods: The research methods used in this study are a quantitative analysis of statistics on the dynamics of world GDP, the global construction industry, the construction industries of developing countries, including Ukraine, the global digital market, digital markets in developing countries, including Ukraine, for ten years using onedimensional statistical methods (UT) based on random sampling. The paper also uses the correlation and regression analysis, namely the linear regression model, as well as the statistical verification of the obtained model by calculating the pair correlation coefficient, the coefficient of determination and the Chaddock scale in the study of the impact of digital technology development on the Ukrainian construction industry. Data and Empirical Analysis: To conduct the study, data were collected and an empirical analysis was conducted regarding the dynamics of world GDP, the world construction industry, the construction industries of developing countries, including Ukraine, the global digital market, digital markets in developing countries,

The article is devoted to the study of green enterprise logistics management and the circular economy incentives used for the implementation of green environmental projects in the countries of the European Union and Ukraine. The article develops methodological approaches and practical recommendations to improve the management system of the enterprise that collects garbage and makes preparations for garbage cardboard and paper recycling. Such system is based on the principles of “green logistics”, taking into account the competitive environment on Ukrainian market. The objectives of the study are the following: elaboration of methodological approaches to the formation of prospects for the development of an enterprise operating in a highly competitive environment; implementation of the strategy of searching and entering new markets for the purchase of raw materials that requires the improvement of the enterprise management system in the context of “green logistics”. A qualitative assessment of the effectiveness of the implementation of the principles of "green logistics" at the enterprise taking into account the economic, social and environmental effects has been carried out in this research. The system for the enterprise management based on the principles of “green logistics” has been proposed. It is recommended to be used at any enterprise that practices the appropriate type of activities (collecting, pressing and preparing cardboard and paper, as well as high-pressure plastic for processing). This approach of the sustainable development of the municipal solid waste treatment industry can be transferred to the country’s entire economy.

Introduction.Compliance of timing of construction works and supply of resources to the site with the works program is an urgent need, because any failure to supply or mismatch of schedules of works and the movement of materials and technical resources may have serious negative consequences for the construction process.Problem Statement. It is necessary to minimize deviations of actual construction terms from those specified in the design documents by creating tools for managing the organization of the construction process based on operational data, their mathematical processing, identification of trends and remedy of deviations based on current information on the course of construction.Purpose. To improve tools and means of the resource logistics and organizational and structural support of construction in order to minimize deviations of the actual terms of the supply of resources to the site from those specified in the design documents at the stage of design works and preparation of CSOS (construction site organization scheme) and SWEP (site work execution program) with seasonal factors taken into consideration. Materials and Methods. The research uses methods of expert estimations, seasonal decomposition of time series, and comparative analysis.Results. The analysis of modern software for the construction of construction, the scheme of organization of the construction project has been established, it is proved that seasonality is a factor that performs moderate influence on the terms of construction and supply of resources, created models of forecasting deviations of the course of the building process taking into account seasonality.Conclusions. The existing methods for forecasting deviations, which are used in the Microsoft Project, OpenPlan, Spider Project, SureTrek Project Manager, Primavera Project Planner, and other software should be added with models designed to predict realistic timelines with seasonal factors taken into consideration. K e y w o r d s : construction, seasonal fluctuations, construction organization, and term of works.

Decomposition of Return on Equity (ROE) after Return on Assets (ROA), Return on Sales (ROS), Total Assets Turnover (TAT) and Equity Multiplier (EM) provides an analytical framework appropriate for observing factors that make and influence profitability. An analysis of the literature makes it clear that classic and modified DuPont models are widely used to analyze the profitability of many industries, including construction. Despite critical feedback from some scientists, this method remains a useful tool for identifying factors influencing the effectiveness of an enterprise, industry, or region. Aims -to calculate the profitability indicators of the "construction" activity enterprises in 1999-2019, to analyze their dynamics and to identify the reasons for the changes. Methods is a widely used Dupont profitability analysis method that involves decomposing the outputs into components in order to identify the effects of those components on the outcome. The profitability indicator analysis of "construction" activity enterprises in 1999-2019 revealed that the construction industry operated at a loss for a decade in a row (2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017), which is reflected primarily in the capital structure. During these years, equity decreased to a critical level; in 2015, uncovered losses exceeded the amount of authorized and reserve capital. Only in 2018 the situation started to level off. Factor analysis of profitability indicators has revealed the in depth factors that affect them, namely: loss of the main activity of construction enterprises for ten consecutive years, which caused a decrease in equity to a critically low level and, accordingly, high values of financial leverage. It can be seen that while in the 2000s, the volume of general sources of financing (the amount of liabilities) was 3.65 times higher than the amount of construction capital, in 2009 -5.2 times, it was 15.5 times in 2019. Therefore, the reverse direction of the financial lever should also be considered. In the case of profitable activity, the financial lever will allow to reach high values of return on equity. But in times of crisis or continuation of a downward trend, this can lead to a loss of financial sustainability in the construction sector.
