Abstract

Purpose: The resolution of this study was to conduct a bibliometric analysis of innovation performance and efficiency of research and development (R&D) expenditure as a proportion of gross domestic product (GDP), to estimate its relative effects on economic growth and productivity. Design/Methodology/Approach: Scopus database was the source of material collected to conduct this study. Selected keywords from literature were combined with Boolean operators and searched. Subsequently a rigorous screening procedure with an inclusion and exclusion criteria was adopted to select the relevant articles for the study. A four prong bibliometric analysis: co-authorship analysis; keyword co-occurrence analysis; bibliographic coupling; and co-citation analysis was then conducted. Findings: From the co-authorship analysis based on countries, the United states emerged with the highest number of documents, followed by China and the United Kingdom, with Italy in the third position. However, China had the greatest number of citations. South Africa, Nigeria and Ghana had 3,2 and 1 documents with 14, 20 and 5 citations respectively. From the results of the keyword co-occurrence analysis, it was observed that innovation, and research and development were the most dominant keywords that reoccurred, indicating that they were the topmost research hotspots. From the bibliographic coupling analysis, it was discovered that articles themed on innovation and R&D subsidies have clouded the research space of innovation performance and efficiency of R&D intensity as a proportion of GDP since 2007 till date. Implications/Research Limitation: It is expected that this study would significantly contribute to theoretical literature by providing a bibliometric record of innovation performance and efficiency of R&D intensity as a ratio of GDP. However, the study uses data from Scopus and limitations of the database have implications for the results. Also, although numerous manual screening criteria were set to filter documents, there may have been subjective bias. Practical Implication: Besides the theoretical contribution of this study, the results would also help governments to plan and instigate research that is geared towards national development. Originality/Value: This distinctive research conducted a bibliometric review of the performance of innovation and efficiency of R&D spending as a fraction of GDP, and corroborated a grave research field that is currently understudied.
