摘要:The subject of the research is the theoretical and methodological principles of the monitoring mechanism of investment development of regions’ infrastructure. The objectives of the research are the generalization of theoretical and methodological bases of monitoring mechanism of investment development of regions’ infrastructure, as well as analysis of the current trends of investment development of the infrastructure in the regions of Ukraine with the identification of positive and negative trends. Methodology. The article deals with theoretical and methodological approaches to the definition of conceptual foundations of the mechanism of monitoring the investment development of the regions’ infrastructure with the help of general scientific methods of analysis: systematization and generalization, induction, and deduction. Results. It is proposed to interpret a monitor of the investment development of the regional infrastructure (IDRI) as a systematic and complex measurement of the indicators of regional infrastructure development, the number of implemented investment projects, monitoring compliance with the developed strategic regional programs and concepts, which will ultimately help to effectively and efficiently regulate the detected deviations and passing the appropriate decisions. The IDRI monitoring mechanism should also provide a possibility of creating a system for collecting and analysing data concerning the assessment of infrastructure objects by the territorial community, which will allow potential investors to focus not only on analytical data on monitoring of regional authorities but also to take into account the public interest in a particular region. The general principles of the monitoring mechanism of investment development of the regions infrastructure are proposed in the following directions: complex and system monitoring and data collection concerning the development of the regions’ infrastructure, while the aggregate of indicators should reflect the change in the level of investment potential as a result of the implementation of measures and implementation of investment projects for the development of regions’ infrastructure; assessing the level of effectiveness of regional infrastructure functioning, using comparative analysis procedures – the concept of benchmarking, which will allow reducing costs of improvement processes accordingly, as the best experience of management of other territories is studied and evaluated in order to use the acquired knowledge in the activities of the authorities. Conclusions. The researched theoretical and methodological principles of the monitoring mechanism of the investment development of the regions’ infrastructure enable to substantiate the necessity of implementation of complex and system monitoring of the functioning of the infrastructure complex and the investment potential of regions. The researched tendencies of investment development of the Ukrainian regions’ infrastructure allowed establishing significant spatial asymmetries, which negatively affects the implementation of both national development strategies and regional programs and concepts. Thus, the main directions of the monitoring mechanism of the investment development of the region’s infrastructure in the composition should be based on analytical observation not only of the regional authorities but also potential investors and the territorial community. Practical meaning. On the basis of official static monitoring data of investment support and the level of development of the infrastructure complex of Ukrainian regions, trends of investment development of the regions infrastructure are investigated in the article, which allows noting about significant territorial imbalances as a level of investment support, as well as the efficiency of the functioning of the regions infrastructure complex, and this determines the need for the development of comprehensive regional development programs and proper control over their implementation in relation to investment regional infrastructure support. The system implementation of the mechanism for monitoring over the investment development of the regional infrastructure will facilitate the adoption of effective management decisions for all participants in the process, namely, the territorial community, investors, and regional authorities, which will increase the investment attractiveness of regions and the development of the Ukrainian regions’ infrastructure.
