六、内容简介
This paper briefly discusses what are NFTs, and where are NFTs going. I introduce a new direct proxy for the public's attention in the NFT market: the non-fungible tokens attention index (NFTsAI), based on 590m news stories from the LexisNexis News & Business database. This index is developed from large-scale text mining to reflect the mimetic and emergent nature of the issues. Furthermore, this index could capture well movements and moments in the non-fungible token space. I further apply the time-varying parameter vector autoregressive (TVP-VAR) model to analyse the connectedness between the NFTs attention index and financial markets. In addition, SADF and GSADF tests are employed to detect price bubbles in the NFT markets.
