Abstract: Data Property Rights （DPR） is a developing concept. At present， to identify the legal attributes of DPR faces three paradoxes： first， as property rights， data bring economic benefits but can be copied； second， as Real Right， data can be the object of real right， but its exclusivity is limited； third， as Intellectual Property， data is intellectual but may not be creative. “20 Articles on Data” has drawn a blueprint for clarifying the legal attributes of DPR in three aspects： first， the “separation of three rights” lays the foundation for the data market； second， DPR operating mechanism should be constructed according to the marketization principle； third， follow the rule of law to protect data property rights transactions. In the future， the legal attributes of DPR will develop in three trends as follows： first， market transactions will promote DPR to become independent property rights； second， administrative regulation will promote data property protection from market regulation to property protection； and third， the legal nature of data property rights changes with technological innovation.
