Abstract: With the continued deepening of electric power system reform and the accelerated construction of new-type power systems, electric power marketing services have exhibited notable characteristics including scenario diversification, stakeholder proliferation, and massive data generation. Consequently, marketing auditing faces unprecedented challenges. Grounded in the practical experience of marketing auditing positions in power supply enterprises, this paper systematically reviews the typical problems confronting electric power marketing auditing under the new circumstances, including insufficient audit coverage capability, relatively outdated technical means, ineffective closed-loop problem rectification, and prominent barriers to cross-specialty collaboration. Drawing on industry best practices, this paper proposes optimization strategies such as establishing a standardized auditing system, promoting digital transformation, deepening closed-loop management mechanisms, and strengthening cross-functional coordination, with the aim of providing references for improving the quality and efficiency of marketing auditing in power supply enterprises.
