The impact of a business incubator on SMEs' innovation in emerging markets is investigated in this study. Furthermore, the challenges that incubators face in helping SMEs improve their innovation. In total, 530 items were discovered, with 56 duplicates removed. The remaining 63 products' philosophies were also eliminated. They were removed because 85 of the remaining 125 relevant articles to the review questions did not address any of the review questions. The abstracts of the remaining xx papers were used to determine their eligibility. Due to muddled abstractions, more than 30 people were also dismissed. As a result, the remaining 171 papers' references and citations were scrutinized more closely.
