Enhancing the quality of public security services is a vital pathway to improving people's well-being,supporting high-quality development,and strengthening the senses of fulfillment,happiness,and security.Using multi-channel retrieval,we identified 471 policy documents on public security services issued between January 2015 and May 2023 by the Ministry of Public Security and provincial public security authorities,and excluded texts outside the study scope.Drawing on policy text analysis and ROSTCM6.0,we construct a PMC-based evaluation index system with 10 first-level and 51 second-level indicators.Indicator content is determined by high-frequency terms in the texts and governance practice,and a binary scoring scheme is adopted to ensure scientific rigor and objectivity.We then randomly select 22 policy documents from the Ministry and various regions,assign values against the index system,calculate the PMC indices,and visualize the results with PMC surface plots.Based on the empirical findings,we propose optimization strategies:increase joint issuance to advance holistic and collaborative governance;diversify policy instruments to enhance flexibility and contextual adaptability;anchor long-term objectives to clarify strategic management planning;encourage local experimentation to spur innovation across the police force.Public security service policies need to clarify the overall planning of strategic management,promote holistic collaborative governance,give full play to the flexibility of the situation,stimulate the vitality of panoramic innovation,promote the optimization of open and transparent government services,and continuously improve the quality of public security services.
