Abstract: University data security governance constitutes a critical component of national data security strategies. By comparing and analyzing 12 data security governance policies in universities in China, the United States, and the United Kingdom, this provides useful reference for the formulation of data security governance policies in universities in China. Firstly, relying on the fusion of feature words and PMC index model. By using text mining to extract feature words, the indicator dimensions of the PMC index model are extracted, and based on this, the model is constructed. Combining the calculation results of the PMC index and the PMC surface graph, a comparative analysis is conducted on 12 policy samples of data security governance in universities in China, the United Kingdom, and the United States. Secondly, through comparative analysis, it was found that the PMC index score of data security governance policies in Chinese universities is the highest, with an average of 7.39, followed by the UK with an average of 6.98, and the United States with an average of 6.55;The three countries of China, the United States, and the UK have strong commonalities in policy functions, policy operability, policy evaluation, and management systems, while there are differences in policy types, policy nature, policy content, technical systems, and operational systems. Finally, policy recommendations are proposed: to reconstruct policy functions and create a "restraining" effect; Improve the technical system and present the method of "processing"; Rebuild the operational system and restructure the state of 'governance'.
