The study is based on primary data collected from 125trade enterprises within the SERVQUAL framework. A multiple linear regression model is employed togetherwith tests for multicollinearity (VIF), autocorrelation (Durbin–Watson) and heteroscedasticity (Breusch–Pagan).The results show that service quality indicators explain 73.1% of the variation in competitiveness, with reliabilityand responsiveness exerting the strongest influence. A step-by-step algorithm for the assessment mechanismis proposed.
