The relevance of research is due to the increasing role of planning in the activities of modern construction enterprises. World and Russian economy is subject to crisis phenomena, which are periodically aggravated, having a negative influence on the results of activities of micro-level economic subjects. The purpose of this research is to improve the process of company planning and rise of effectiveness at the building enterprises. The object of the research is building enterprises and the entire set of planning processes implemented on them in order to improve the effectiveness of their processes. The subject of the research is the organization and economic relations appearing in the process of functioning of building enterprises and planning of their activities in modern conditions. The author investigated the state and prospects of the development of building complex of the Irkutsk region, analyzed the organizational structure of management of a number of building enterprises, as a result, disadvantages in the planning of organizational work at these enterprises were revealed. The basic concepts of planning presented in the scientific and economic literature were researched, summarized, and refined, the essence of enterprise’s planning activity in market conditions was determined, stage-by-stage model of company planning, which allows to systematize this process, was developed. The author’s model covers the strategic and tactical aspects of company planning, which includes several successively related stages. The methodology of research is based on the use of general scientific methods, aimed to understanding the process of function planning of building enterprises. Elements of systematic and complex approach, methods of economic, logical, comparative analysis, scientific search and classification were used in the course of the study.

The relevance of the study is conditioned by the need for structural reforms in the regional investment and construction complex, caused by the transition of the Russian economy to an innovative way of development. The purpose of this study is to improve the mechanism for restructuring of the regional investment and construction complex, and to develop a step-by-step model for its implementation. Based on the analysis of the state of the regional investment and construction complex, factors that adversely impact the efficiency of innovation processes in the regional economy and issues that hamper development of the regional investment and construction complex are revealed. A mechanism for restructuring of the regional investment and construction complex has been developed, which includes five interrelated elements: target functions, links of the mechanism, and normative, strategic and operational subsystems that allow reflecting the transformations implemented in the regional economy as a whole, and in the investment and construction complex of the region in particular. A step-by-step model for the restructuring of the regional investment construction complex is proposed, the practical use of which will improve the performance of the investment and construction complex, the enterprises that make up its structure, as well as the indicators of the region’s economic development as a whole. A system of equations is proposed, with the help of which it is possible to describe changes in interaction with the economy of a particular region in the regional investment and construction complex and the enterprises that make it up. In the work, methods of systemic analysis and tools of mathematical statistics and economic and mathematical modeling have been used.

The purpose of the current research is identification of problems that the investment and construction business faces in conditions of innovative economics. The urgent necessity to systematize these problems and find ways of their solution determined the relevance of the research. Using the methods of statistical processing of information, economic groups and logical analysis, the authors assessed innovative activity of enterprises, concluded that it was reduced, and pointed out the main problems of the investment and construction sphere. The problems include technological backwardness and low level of innovation, insufficient qualification of stuff, which is able to generate and introduce innovations in construction, and lack of attention of company management to the strategic aspects of innovation. The problem of investment and construction enterprises related to the restoration of business that suffered from pandemic is especially highlighted. These problems are closely related to the low level of investment in the innovative development of the construction business. Financing of the innovative activity is directly related to all participants of the innovative process. It is necessary to organize a clear mechanism for participants’ interaction. As a result, authors of the current research classified the participants of the innovative process in investment and construction business, determined their functions. The authors suppose that the problems of innovative financing are the most significant. In this connection, the problem of venture financing of the innovative activity is considered in more detail and solutions are offered.

This article shows the results of a socially significant research, the relevance of which is constantly growing in current conditions, due to the impending global crisis. Research objectives are to develop theoretical knowledge in sphere of quality ecological assessment of the urbanized territories and identification of opportunities for their practical use in certain regions. Authors have systemized factors that affect on the quality of urban environment and identified main approaches, which are used in implementing of the quality ecological assessment of the urbanized territories’ environment. Results of ecological and hygienic assessment of air quality of Irkutsk Region’s (Russia) cities have been introduced as a part of the author’s methodology. Main sources of pollution and their impact on atmospheric pollutant emissions have been identified. Urban areas with high level of air pollution have been revealed. Based on the findings, set of measures has been proposed to restore ecological balance in Irkutsk region, the implementation of which will improve the environmental conditions of atmospheric air as one of the criteria of quality assessment of urban territories. Methods of systemic and comparative analysis, expert opinions and social polls as well as ecological monitoring of the environment have been used during the research.
