In the era of big data,data is regarded as a valuable property due to its objective value.Because differ-ent data subjects have objective needs for balancing the interests of data propertization,the establishment of a system for data propertization is both rational and necessary.China has already had legislative,judi-cial,and policy foundations for data propertization.Data sharing is both the cause and the result of data propertization.The propertization of data in China should adopt a basic legislative model that protects both the right to personal data and property rights.However,a control theory model should be applied to regu-late government data and sensitive corporate data.In addition,regarding data sharing between individual users and enterprises,this paper suggests a transaction model based on data property rights should be a-dopted before the sharing.For data sharing among enterprises,this paper recommends that based on prac-tical cases,data categorization and scenario-based laws should be established from the bottom up to clarify and distribute the specific content of corporate data property rights.
