Moreover, natural sciences and engineering/technology still dominated the SDG-related research databases compared with social sciences. In fact, this has been underlined in many SDG-related studies, in which some stated how vital science and technology were for SDGs [83, 84], while some other papers focused on the roles of science and technology in itemized issues such as food security and safety [85, 86], risk reduction [87], and industrial innovation and upgrade [88]. A relatively high number of citations of business and economics papers could reflect the real motivations of the commercial and financial sectors to adopt SDGs, as explained by the UN and many firms and consulting compa \begin{table}

nies [57; 58; 59]. Those medicine and public health-related fields demonstrated how SDG 3 was of significant concern again. Besides, development studies could be linked to the general sustainable development studies, and energy echoed the emerging importance of climate change issues [26; 89; 90]. Figure 2 illustrates the number and trends of citations in the top eight fields. The numbers in the top year for each field were also presented. The citations of most fields dropped significantly after 2020, with \"Business and Economics\" the exception.
