Abstract

This article analyzes the relationship between service quality indicators and economic efficiency using
econometric methods. The study evaluates the regression relationship between quality indicators such as customer
satisfaction index, service speed, number of complaints, and economic indicators such as profitability, labor productivity,
and revenue. The results obtained confirm that an increase in service quality increases economic efficiency to a statistically
significant extent.
