Functional Expansion and Developmental Scenarios of Management Accounting Based on Data Analytics Modelling

This paper explores the theory and practice characteristics of management accounting, expands upon the function of management accounting, and outlines the business process of strategic management accounting. Then, it constructs the functional effect analysis model of management accounting, establishes the causality analysis model of the structural equation, explores the markov property of the equation, and uses multiple linear regression equations to estimate the regression parameters. Finally, it analyzes the correlation between the overall level of strategic management accounting, the application level of management accounting, and the horizontal integration level of management accounting and enterprise performance. According to regression analysis, the three dimensions have a significant positive correlation with enterprise performance at the 1% level. The structural equation analysis indicates that the path coefficient of management accounting on performance is 0.388, which is significant at a 1% level. The application of management accounting can have a positive impact on the performance level of enterprises, as shown. This research promotes the innovative practice of management accounting and is of great significance for the high-quality development of enterprises.
