Abstract: 【Purpose/significance】User participation has an important impact on the resource utilization,value realization and sustain-
able development of the“Belt and Road”thematic database.It is particularly important to establish an incentive mechanism for user
participation in the“Belt and Road”thematic database【. Method/process】This paper analyzes the user participation roles and motiva-
tion of database construction,and uses literature research method to learn from the relevant practices of the user participation incentive mechanism.An incentive mechanism for user participation in the“Belt and Road”thematic database has been constructed.【Result/conclusion】User participation roles are divided into five categories:planning advisers.resource contributors,resource descriptors.,re-source reviewers,maintainers and evaluators.The motivations for their participation include intrinsic motivation and extrinsic motiva-tion.It is proposed to give priority to honor incentive and emotional incentive,supplemented by interest incentive, as the "Belt and Road" thematic database construction user participation incentive mechanism.The honor incentive mechanism includes points-rank-ing incentives.badge incentives,and written approval incentives.The emotional incentive mechanism includes interesting task setting and humanized system design.It will jointly serve the whole process of the construction of the“Belt and Road”thematic database【. In-novation/limitation】The user participation incentive mechanism constructed serves the whole process of the "Belt and Road" thematic database construction.It can effectively improve user participation and loyalty,and further exert the value of the "Belt and Road" the-matic database.
