[Purpose/significance] This paper conducted policy synergy assessment for the two policy groups of open scientific data policy and personal data protection policy with the method of policy text content analysis,in order to make policy suggestions for the formulation and improvement of the current open scientific data policies from the research perspective of quantitative analysis of policy texts. [Method/process] This paper first firstly selected some benchmark policies from the two policy groups of open scientific data policy and personal data protection policy,secondly constructed the policy text content analysis units of policy synergy observation between the two types of policy groups through the content analysis method,and then conducted policy synergy assessment for the two types of policy groups through the contrast analogy method,and finally made policy suggestions for the formulation and improvement of the current open scientific data policies through descriptive inference for the results of above policy synergy assessment. [Result/conclusion] It is recommended that the main policy subjects of the various stakeholders develop and publish independent personal protection policy documents as soon as possible,and formulate more complete and detailed policy contents related to personal data protection based on all the data lifecycle phases involved,and also supplement,adjust and improve the relevant policy contents of data rights,processing purposes,processing methods and so forth according to the newly introduced personal data protections laws.
