Abstract

The retail sector in Brazil has been making great strides in recent decades, going from revenue of R$224.3 billion to R$611.2 billion in 2021, a result that reflects 7.03% of the Brazilian World Domestic Product (GDP), being one of the most important sectors of the country's economy (ABRAS, 2022). Intense competition has been causing changes in the service offered by the sector, redefining traditional activities in order to attach characteristics of other formats or directing its activities to a more specific niche. This study aims to carry out a historical analysis of efficiency, from 2013 to 2022, of the retail chains listed in the 2022 ABRAS Ranking in the state of Rio de Janeiro, using the DEA (Data Envelopment Analysis) calculation. Through the analysis, it was observed that establishing a single criterion of organizational and operational performance based only on revenue results does not reflect the relative efficiency of each retailer. The results showed that of the 21 retailers presented in the ranking, only eight showed maximum efficiency in the year 2022. Three of these were positioned after the tenth place in the ABRAS 2022 ranking.
2013年至2022年间里约热内卢州超市部门的效率
近几十年来,巴西的零售业取得了长足的进步,从2243亿雷亚尔的收入到2021年的6112亿雷亚尔,这一结果反映了巴西世界国内生产总值(GDP)的7.03%,是该国经济中最重要的部门之一(ABRAS, 2022)。激烈的竞争导致该部门所提供的服务发生变化,重新定义传统活动,以便附加其他形式的特征,或将其活动导向更具体的利基。本研究旨在使用DEA(数据包络分析)计算,对里约热内卢州2022年ABRAS排名中列出的零售连锁店的效率进行历史分析,从2013年到2022年。通过分析,我们观察到,仅仅基于收入结果建立单一的组织和经营绩效标准并不能反映每个零售商的相对效率。结果显示,在上榜的21家零售商中,只有8家在2022年效率最高。其中3个在ABRAS 2022年排名中位于第十名之后。
