Improvement of the mechanism of management accounting of enterprise expenses in the conditions of clusterization

The object of research is the implementation of clustering of the economy as an effective mechanism for management accounting of the costs of enterprises. One of the most problematic areas is the identification of the main priority areas of clustering the economy, which will actively influence the development of management accounting of enterprises' costs. The use of a cluster mechanism for management cost accounting, thanks to management, information, personnel, financial, investment, and innovation potential, will create a research base for developing cost accounting methods and assess the prospects for its use in clusters.The analysis of the current state of the introduction of clustering of the economy is made on the example of Ukraine. The main characteristics of the directions of development of the introduction of clustering of the economy have been determined. The main priority areas of clustering of the economy will actively influence the development of management accounting of enterprises' costs.In the course of the study, approaches to clustering the economy as an effective mechanism for management accounting of enterprises' costs are used. The stages of the introduction of clustering of the economy as an effective mechanism for management accounting of the costs of enterprises are determined. These stages provide for the determination of the role of clustering the economy in creating an effective mechanism for accounting for expenses in clusters and the development and implementation of action plans for its implementation. The next step is to analyze the implementation of management accounting of expenses in clusters and develop the principles of its formation. For their implementation, it is proposed to develop directions for the development of the introduction of clustering of the economy and to present the cluster mechanism as an effective factor in improving the management accounting of enterprises' costs. Thanks to this, it is possible to prevent and solve the problems of management accounting of expenses in clusters and to increase the efficiency of the cluster association. In comparison with similar well-known methods, the proposed approaches allow to form an effective management cost accounting system and improve management in clusters using the cluster approach
