Abstract: Network information security policy is an important institutional guarantee for maintaining national security and development, and analyzing the institutional framework and rule characteristics of Chinese network information security policies is of great significance for enhancing its implementation effect of network information security policies. Coding statistics of 39 network information security policies, based on the components of institutional grammar tool (IGT), this paper highlights the complex orientation of the institutional framework of Chinese network information security policies from five dimensions: actors, action constraints, action scenarios, action goals, and evaluation results. Based on the framework of the system，focusing on the function definition rules, exit access rules, decisionmaking guidance rules, information transfer rules, and rewards and punishments incentives rules in the institutional analysis and development (IAD) framework, it is found that the current Chinese network information security policies are characterized by the rules of ambiguous definition of departmental rights and responsibilities, missing access conditions of the main body, weakening of the statement of the regulatory strength, poor reverse feedback channels, and unequal distribution of the rewards and punishments. In view of existing problems, in the future, the effectiveness of regulation can be improved by clarifying the rights and responsibilities of departments, adding access conditions, adding rulebased statements, optimizing feedback channels, and improving incentive and punishment measures.

摘要： 网络信息安全政策是维护国家安全和发展的重要制度保障，分析我国网络信息安全政策的制度轮廓与规则特征，对于提升网络信息安全政策的实施效果具有重要意义.对39份网络信息安全政策文本进行编码统计，基于制度语法工具(institutional grammar tool, IGT)的构成要素，从行动者、行动约束、行动情景、行动目标、评价结果5个维度彰显我国网络信息安全政策制度轮廓的复杂面向.在制度轮廓基础上，围绕制度分析与发展(institutional analysis and development, IAD)框架的职能界定规则、退出准入规则、决策指导规则、信息传递规则和奖惩激励规则展开分析，发现当前我国网络信息安全政策存在部门权责界定模糊、主体准入条件缺失、陈述规制力度弱化、逆向反馈渠道不畅和奖惩措施分配不均等规则特征.针对存在问题，未来可通过明确部门权责、增设准入条件、增加规则型陈述、优化反馈渠道与完善激励惩戒措施提升规制效力.
