  The data circulation is a complex scenario involving a large number of
participants and different types of requirements, which not only has to comply
with the laws and regulations, but also faces multiple challenges in technical
and business areas. In order to systematically and comprehensively address
these issues, it is essential to have a comprehensive and profound
understanding of 'data circulation'.
  The traditional analysis method tends to proceed based on the traditional
circulation model of commodities, that is, tangible objects, which has some
defects and shortcomings, and tends to be a formalized approach, which is faced
numerous challenges in practice. This paper analyzes the circulation of data
with a philosophical approach, obtains the new explication of data and
executing entity, and provides a new definition of the concepts of data
utilization and data key stakeholders (objects). At the same time, it puts
forward the idea of ``data alienation'', and constructs a new interpretive
framework of ``data circulation''.
  Based on the framework of this interpretation, it is clearly proposed that
``data alienation'' is the core of ``data circulation'', benefit distribution
is the driving force, and legal compliance is the foundation, and further
discussed the three modes of ``data circulation''. It further discusses the
three modes of ``data circulation''. It is pointed out that ``data
circulation'' is different from traditional ``commodity circulation''. To
achieve ``data circulation'',a comprehensive information infrastructure needs
to be established. from a theoretical point of view, it lays a solid foundation
for the development of ``data circulation''.
