Abstract: 【Purpose/significance】This paper explores the relationship between postgraduates' attitude towards scientific
data sharing and willingness to share scientific data, constructs a data sharing willingness model, and analyzes relevant in⁃
fluencing factors, so as to provide reference for the practice of data sharing and application.【Method/process】Through the
questionnaire survey of graduate students and doctoral students, combined with TAM, the scientific data sharing model is
constructed, and AMOS is used to verify the model. The verification results are analyzed, the hypothesis is modified, and
the relevant theoretical model is obtained.【Result/conclusion】Through the structural model test, it is found that there is a
NIMBY phenomenon when the attitude and willingness of scientific data sharing are different. Combined with data analysis,
we get the scientific data sharing NIMBY model. At the same time, the data analysis shows that perceived risk is the main
reason for the existence of NIMBY phenomenon in data sharing, and data sharing experience has an important impact on da⁃
ta sharing willingness. On the basis of interviews, this paper explores the construction of data sharing acceptance model to
promote the willingness of data sharing, so as to solve the problem of NIMBY phenomenon in current data sharing, and pro⁃
vide reference for scientific data sharing practice.
