Abstract:

【Purpose/significance】 The "14th Five-Year Plan" clearly points out the importance of network security, information secu⁃

rity and data security, and information confidentiality is highly valued by China and the Communist Party of China. Exploring and re⁃

vealing structural characteristics of information confidentiality policy can help us to sum up the experience of policy construction and

improve the system of information confidentiality policy in China.

【

Method/process】 This paper constructs a "Subject-Tool-Theme"

three-dimensional analysis framework, and uses text content analysis and social network analysis to reveal the cooperation mechanism

of the subject, the arrangement of tools and the correlation effect of the theme in China's information confidentiality policy.【Result/

conclusion】 Through the analysis of 185 policy texts, it is found that China's information confidentiality policy has obvious structural

characteristics and presents a stable development trend in the three dimensions of subject, tool and theme. In view of the current prob⁃

lems of insufficient coordination of subject, structural imbalance of tool application and lack of comprehensiveness of theme direction,

suggestions were put forward to improve the multi-subject coordination policy system, promote the optimization and balance of three

types of policy tools, and focus on the policy theme at the technical standard level.【Innovation/limitation】An analysis strategy of infor⁃

mation secrecy policy that integrates three dimensions of policy subjects, policy tools, and policy themes has been explored, but it

lacks in-depth cross-dimensional analysis.
