PENGARUH KUALITAS AUDIT, AUDIT EKSTERNAL, EARNINGS POWER, DAN EFISIENSI OPERASIONAL TERHADAP KINERJA BANK DI BEI

Abstrak

This study examines the effect of audit quality, external audit, earnings power, and operational efficiency on the performance of banks listed on the Indonesia Stock Exchange. It replicates Alsmady (2022) and adds the operating expense to operating income ratio (BOPO) as a measure of efficiency. Panel data of 16 banks for 2015-2022, selected by purposive sampling, were analyzed in EViews 12 with bank size, age, and leverage as controls. Performance is measured by two market-based indicators (Tobin's Q and market-to-book ratio) and two accounting-based indicators (earnings per share and return on equity). Earnings power is the most consistent determinant: it has a positive and significant effect on market-to-book, earnings per share, and return on equity, but a negative and significant effect on Tobin's Q. Audit quality, measured by Big Four auditors, raises earnings per share only. External audit, proxied by working capital, shows no positive effect on any measure. Operational efficiency improves earnings per share, while its coefficient on return on equity has the opposite sign. Only five of the sixteen hypotheses are supported, so bank managers should prioritize earnings power and cost control.
