COVID-19 and SMEs: An umbrella review of systematic literature (2020–2024) and future directions for entrepreneurship

Abstract This special issue addresses the impact of COVID-19 on entrepreneurship. It builds on insights shared at the dedicated session – supported by the Hungarian Academy of Sciences' Post-COVID research grant (MTA PC-II-17/1/2022) – of the 2nd Danube Cup Conference in Belgrade in November 2023, featuring three papers presented there, along with four additional contributions. The goal of this issue is to advance scholarly understanding of post-COVID dynamics in entrepreneurship and share valuable findings with a broad academic audience. To provide a comprehensive overview of current research on this topic, we include an umbrella review examining the COVID-19 crisis' impact on small and medium-sized enterprises (SMEs) from 2020 to 2024. Drawing on 26 systematic literature reviews identified through Scopus, Google Scholar, and Elicit, this review captures key challenges, strategies, and emerging trends affecting SMEs. Major research themes identified include resilience, supply chain management, digitalization, crisis management, and the financial impact of COVID-19.
