With the steady advancement of the construction strategy for emerging engineering disciplines and the explosive proliferation of domestic operating system industrial ecosystems, cultivating compound technical talents proficient in distributed application development based on HarmonyOS has evolved into an indispensable strategic pathway to foster high-quality growth within the digital economy sector and safeguard national critical information security infrastructure. At present, undergraduate and vocational colleges are plagued with multiple structural drawbacks in the delivery of HarmonyOS application development curricula, including stagnant teaching content that lags behind iterative technological breakthroughs, rigid instructional methodologies disconnected from real-world industrial engineering scenarios, as well as monotonous, ossified student performance evaluation frameworks. Such systemic defects fundamentally fail to satisfy the core training objectives of emerging engineering education, which prioritize interdisciplinary competence, innovative thinking and hands-on engineering practice. Grounded in the core ideological connotation of emerging engineering construction, this paper integrates the proprietary technical architectures of HarmonyOS and the actual talent recruitment demands of downstream industrial enterprises. It systematically dissects the intrinsic value and feasible implementation avenues of curriculum renovation, and puts forward targeted, operable reform countermeasures. The research outcomes are intended to optimize the overall curriculum architecture, elevate comprehensive instructional quality, and furnish solid theoretical references and actionable practical inspirations for institutions of higher learning undertaking homologous curriculum transformation initiatives.
