Blockchain Technology and Accounting Information Quality: Multi-dimensional Mechanisms and Industry Heterogeneity Evidence

Abstract

This study explores how blockchain technology enhances enterprise accounting information quality through a mixed-methods approach combining theoretical analysis and empirical testing. By constructing a "technology characteristics-quality dimensions-market efficiency" theoretical framework, we examine the specific mechanisms by which blockchain's decentralization, immutability, traceability, and transparency affect accounting information reliability, timeliness, and comparability. Using machine learning techniques on data from listed companies across retail, finance, and manufacturing sectors, we verify significant improvements in accounting information quality post-blockchain implementation, with notable industry heterogeneities. The research contributes a blockchain accounting maturity model and provides practical guidance for enterprises and regulatory authorities in promoting digital transformation of accounting systems.
