Assessing global interest in decentralized finance, embedded finance, open finance, ocean finance and sustainable finance

Purpose - This paper analyzes global interest in Internet information about decentralized finance (DeFi), embedded finance (EmFi), open finance (OpFi), ocean finance (OcFi) and sustainable finance (SuFi) and the relationship among them. Design/methodology/approach - The paper used a comparative methodology based on regression and correlation analyses to assess global interest in Internet information about DeFi, EmFi, OpFi, OcFi and SuFi. Findings - The findings reveal that global interest in Internet information about EmFi was more popular in Asian and European countries. Global web search for Internet information about OcFi decreased during the financial crisis while global web search for Internet information about OpFi and EmFi increased during financial crisis years. Global web search for Internet information about DeFi, SuFi and EmFi increased during the pandemic years. There is a significant and positive correlation between interest in DeFi, EmFi, OcFi and SuFi. Also, there is a significant and negative correlation between interest in EmFi and interest in OpFi. The regression coefficient matrix shows that OpFi, EmFi, OcFi, DeFi and SuFi are significantly related. Originality/value - To the best of the author's knowledge, this is the first paper that analyses the association between interest in DeFi, EmFi, OpFi, OcFi and SuFi. Thus, this study addressed an important knowledge gap in the literature by exploring people's interest in Internet information about DeFi, EmFi, OpFi, OcFi and SuFi.
