This research used Veblen’s Institution Shift Theory, and adopted mixed methods such as
network survey, literature survey and comparative study. The core research findings are as
follows:1) Originated from the rapid development and wide application of digital technology, the
development of data economy should experience three stages: data-based economy, data-driven
economy and data-enabled economy. The evolution from the direct value of data exchange to
digital industrialization and industrial digitization reveals that there are different representative
key technologies, data industry scales, data value transformation modes and functioning space
at different development stages. 2) The emergence and development of digital economy have
brought about data economy, which is an important part of digital economy and an essential stage
of development. The relationship between them is both independent and complementary, and data
economy could promote the development of digital economy to a more intelligent stage. 3) Along
with the technological upgrading, the supply side of data/services and the demand side of industrial
intelligence updating, it can be found that the circulation of the three elements is progressive.
Meanwhile, the operation characteristics of data economy have been found, such as the field of
data economic activity is from partial to overall, value-added space from a single process to the
whole process, market structure from static decentralization to dynamic concentration, market
relationship from individual competition to coordination and mutual benefit. Therefore, from
the development of data economy to the advanced stage of digital economy, there needs to be
a huge overall change, rather than a partial change in a certain industry. 4) Currently, there are
still many obstacles and problems in the process of data as a factor of production and its role in
market allocation, various types of data conflicts, including data sovereignty and rights protection,
monopoly and competition, fairness and efficiency, which should be resolved as soon as possible.
