Drawing on the management methods, means and system design of land finance, it focuses on the operation process of marketization of data elements, and discusses the feasibility framework of data finance from core issues such as participants, government data operation system, and implementation paths. And it is proposed that the focus should be placed on breakthroughs at the institutional and technical levels required by the data finance system, especially in conjunction with the new digital economic infrastructure built at the national level to fully support the implementation of data finance. At the same time, in order to give full play to the specific functions of each market entity, data finance should be combined to realize the coordinated governance of multiple market entities and market relationships, thereby promoting digital transformation and the sustainable development of the digital economy.
