推进教育数字化需要行之有效的政策体系支撑，教育数字化政策的量化评估结果可为教育数字化政策的废、改、立提供必要的参考价值。文章基于2018—2023年中央及地方层面出台的100项教育数字化政策，采用文本挖掘和PMC指数模型等方法构建出由政策性质、政策时效及政策措施等10个指标构成的评价体系，并结合PMC指数、曲面图和雷达图有针对性地选取7份政策文本进行了系统深入的评估分析。结果表明：我国教育数字化政策整体指向明确，国家级和省级政策相比，各项一级变量均值相差不大，但在政策性质、政策时效和政策保障方面存在诸多差异。建议政策的制定应注重整体时效性，并有助于弥补经济发达地区与经济欠发达地区的差距；且须明确责任主体，筑立监控体系；同时完备制度保障，确保执行效果。
【英文摘要】：
The promotion of the digitalization of education requires the support of an effective policy system. The results of quantitative assessment of education digitalization policies can provide necessary reference for the abolition, amendment, and establishment of such policies. Based on 100 education digitalization policies issued by the central and local government from 2018 to 2023, this paper used the text mining and PMC Index model to construct an evaluation system consisting of 10 indicators, such as policy nature, policy timeliness and policy measures. In addition, seven policy texts were selected for systematic and in-depth evaluation and analysis based on PMC index, surface chart and radar chart. The results showed that the overall direction of China's education digitization policy was clear, and the mean values of all first-level variables did not differ much between the national-level and provincial-level policies. However, there were many differences in terms of policy nature, policy timeliness and policy guarantee. It is suggested that the formulation of the policy should pay attention to the overall timeliness and help to bridge the gap between the East and the West. And it is necessary to clarify the main body of responsibility and build a monitoring system, as well as to complete the system guarantee to ensure the effectiveness of implementation.
