Abstract: With the acceleration of digitalization,data have become a core resource across industries,driving continuous market growth.However,the current data trading market remains underdeveloped,mainly due to two reasons.Firstly,the high barriers for individuals to trade behavioral data.Secondly,the lack of sound compliance review mechanisms for inter-enterprise data tran-sactions,with incomplete trading rules that restrict market vitality.The fundamental difficulties in data trading lie in the unique characteristics of data,which differ from traditional “cash-and-carry” goods,leading to challenges in pricing,data rights confirmation,data quality assurance,non-repudiation of transactions,and the safeguarding of data sovereignty.This paper collects and organizes relatively mature data trading frameworks,classifies and compares them from the perspective of trading models,and provides a detailed introduction to the solutions proposed in the literature for the five major challenges mentioned above.Finally,in light of the current development of the data trading market,this study puts forward suggestions for future development.

Key words: Challenges in data trading, Data rights confirmation, Data pricing, Data sovereignty, Data quality assurance, Non-repudiation in data trading
