A model of accounting and analytical support of cost optimization in the context of new institutionalism

Subject. This article deals with the theoretical and methodological features of the formation of accounting and analytical support for transformation and transaction cost optimization.
Objectives. The article aims to indicate the need to classify costs according to their belonging to transactions and disclose the theoretical and methodological features in the context of accounting and analytical cost optimization support.
Methods. For the study, we used general scientific methods (analysis, comparison and interpretation) and statistical methods in economics. The results of the study are shown in tabular and graphical forms.
Results. The article defines the notion of Transaction Cost and the need to decompose cost into transformation and transaction parts to take measures to optimize the level of costs. It systematizes the theoretical and methodological features of accounting and analytical models for transformation and transaction cost optimization. The article also proposes to integrate digital technologies into the management cost accounting system.
Conclusions and Relevance. The article justifies the necessity to break costs into transformation and transaction parts for these types of cost have different approaches to the accounting and analytical support formation for optimization. The organization of accounting and analysis of costs by their belonging to transactions can improve the quality of accounting and analytical support and, consequently, the information base for management decisions. At present, the digital technologies that can be used in financial and operational activities contribute to cost reduction.
