“…Similarly, each color represents a cluster, and the link between the nodes indicates the co-occurrence of these two keywords. The distance between keywords directly reflects their relevance, and the shorter the distance, the stronger the relationship between them ( Shi et al, 2020 ). In the first dataset, we set the minimum number of occurrences of a keyword to 100, and 193 keywords met the threshold of the 28,661 keywords were divided into four clusters.…”

“…Firstly, Bibliometrix was used to conduct the keywords frequency analysis by obtaining information of the keywords frequency from the data set. After merging some keywords with the same meanings, the resulting keyword count lists were used to generate a word cloud of keywords of the SC field (Figure 2), which is an entire and clear graphical display of hot topics around sustainability at the community level (Shi et al, 2020). In Figure 2, the size of the keywords is positively correlated with the keywords frequency.…”

“…This method can provide valuable insights into the characteristics and structure of a specific research domain in a systematic, transparent and reproducible process (Broadus, 1987; Kamalski & Kirby, 2012). It provides a more reliable and objective analysis than other techniques (Aria & Cuccurullo, 2017) and have proven effective in literature analysis in different disciplines (Shi et al, 2020). The bibliometric approach of this study involves three major steps, as described below.…”

“…(2) Conceptual structure analysis. The keywords are distributed in the form of dots in the two dimensional space, clearly revealing the relationship between them and the spatial distribution of the themes (Shi et al, 2020). To be specific, the stronger the relevance of the keywords, the closer they are presented in the concept structure diagram.…”

“…Researchers are key participants in driving the development within a particular field, and the productivity and impact are usually deemed as two important facets for measuring their contributions (Forliano et al, 2021). In this representation, the area of the circle is proportional to the number of publications per year, and the colour depth concerning the circle is proportional to the average annual citations since publication (Shi et al, 2020). (2) Conceptual structure analysis.…”
