Abstract: Abstract: In the era of digital economy, the digital and intelligent transformation of the accounting industry presents new challenges for vocational talent cultivation. Kunming Metallurgy University's Big Data and Accounting major explores the "Job-Course-Competition-Certificate" integrated education model. This model reconstructs the "foundation-core-expansion-practice" four-level progressive curriculum system, integrating new technologies such as intelligent finance and accounting robots, and builds a curriculum system that links jobs, courses, competitions, and certificates. Supported by a provincial-level High-Level Higher Vocational College professional group and dual-teacher team, a "business scenario + simulation training" hybrid teaching model is created, achieving a "1+X" certificate pass rate of over 90% and a breakthrough in national skill competition awards. The practice shows that this model bridges the structural gap between educational supply and industrial demand through "four-chain integration" ecological reconstruction and "digital and intelligent empowerment" teaching innovation. However, challenges such as lagging curriculum updates and data silos remain. Future reforms should focus on co-developing industry standards and deepening the application of artificial intelligence in tracking learning growth, providing a replicable model for the high-quality development of vocational education.
