【摘要】 2018年《大气污染防治行动计划》已完成终期考核,对政策主题变迁规律的分析能为下一阶段政策制定提供决策依据。以2005—2018年128篇国家级大气污染治理政策为分析样本,构建文本关键词关联网络,通过凝聚子群识别和主题相似度计算得到不同历史阶段的政策主题变迁路径,进而对政策变迁规律和未来趋势进行分析。研究发现,大气污染治理政策主题变迁特征以演化、融合主题为主,同一主题在相邻阶段出现较少;政策颁布主题由面及点;政策措施由单一向复合转变;技术创新的作用不断加强。"重污染地区和时期的区域间联防联控""能源和重点行业深入改造升级""节能减排技术设备的研发与应用"将是十三五后期乃至更长时间内大气污染治理的重点主题。更多还原

【Abstract】 Based on the final assessment in 2018 of The Air Pollution Prevention and Control Action Plan, the paper has made an analysis on the pattern of policy topic changes in view of providing a decision-making basis for policy promulgation in next stage. Using 128 national air pollution control policies in 2005-2018 as samples, the text keywords correlation network is constructed, the change path of policy topics in different historical stages obtained by subgroup recognition and topic similarity calculation, and the pattern of policy topic changes and future trends analyzed. It is found that the patterns of topic evolution and integration appear in the adjacent stage of topic change paths, and no same topic is found; policy topics are changed from general to specific; the measures from single to compound; and the role of technological innovation is constantly strengthened. The key topics of air pollution control in the late 13 th Five-Year Plan and even longer period will be the "joint control of interregional defense in areas and periods of heavy pollution", "further upgrading of energy and other key industries" and "R&D and application of energy saving and emission reduction technology and equipment".更多还原
