Mapping the Scientific Shreds on Barriers to SMEs’ Innovation

The present study aims to showcase the vital contributions to innovation barriers in the context of small and medium enterprises (SMEs) for 1975–2022. With the help of VOSviewer, this bibliometric analysis employs a quantitative method based on documents retrieved from SCOPUS database to assess historical patterns, results and the key elements affecting open innovation in SMEs. The results show an upward trend of research publications in the totality of the 222 documents contributed by 160 authors from 59 countries. The majority of research was conducted in developed countries. Findings also reveal the most cited research articles, keyword analysis, country collaboration and the number of documents published yearly. Language bias may occur as this bibliometric study only included literature written in a single language. Consequently, studies released in other languages may go unnoticed. This study is helpful for policymakers to provide a conducive environment for innovation among SMEs to keep economic growth on priority. This study offers the first comprehensive assessment of innovation barriers in a holistic manner. With the help of bibliometric analysis, the study assesses the intellectual framework of open innovation in SMEs.
