Abstract: Market circulation of data elements is a key link to activate the economic and social value of all kinds of data and build a data resource system, which directly affects the effectiveness of the construction of digital China. Government data authorization operation and data trading platform are two main modes of market circulation of data elements. In this study, eight market-based circulation platforms with data elements were selected to carry out comparative analysis from six dimensions, including the composition of working capital, platform participants, platform data sources, product and service types, data rights confirmation paths and technical solution applications. Based on the analysis results and the information ecology theory, this findings show that the data element market ecosystem is composed of data products and services, data subject, data platform and data environment. The ecosystem needs the support of the cooperation mechanism of data community, the linkage mechanism of the two modes and the interaction mechanism between inner and outer circles. This study has significant implications for future development: It is necessary to enrich and innovate application scenarios to drive the integrated development of data elements, establish income distribution mechanism to crack the conflicts of interest among data subjects, and promote the safe and reliable market circulation of digital technology, so as to promote the construction of market circulation ecosystem of data elements.
