| 以新浪微博为数据源，基于LDA主题模型构建话题分类模型，识别能耗双控话题相关
文本中的7个舆情话题，并从话题内容、数量和时空分布等方面分析2021年9月20日至10月20日
的舆论响应分布特点。研究发现：（1）话题内容整体呈现积极情感导向，主要围绕生活、生产、管理
3个相关角度；（2）各话题响应时序存在明显差异，生活相关话题最先得到广泛响应，生产相关话题
次之，而管理角度的理性分析话题存在滞后性；（3）各类话题存在空间差异，生活、管理角度话题讨
论高值区主要集中在东北地区，生产角度话题讨论集中在长三角、珠三角等秦岭、淮河以南地区；
（4）舆情发展过程中加工贸易相关行业和第三产业对于能耗双控政策的敏感性较高。 |

| This paper used Sina microblog as the data source to construct a topic classification model based on the LDA
topic model, identify seven opinion topics in the texts related to energy consumption dual control topics, and analyze the
characteristics of nationwide opinion response distribution from September 20 to October 20, 2021 in terms of topic content,
quantity and temporal distribution. The findings are as follows: (1) The overall topic content is positively emotionally orient⁃
ed in terms of three related perspectives of life, production and management; (2) There are obvious differences in the re⁃
sponse time sequence of each topic, with life related topics receiving extensive responses first, followed by production,
while rational analysis topics from the management perspective have a lag; (3) There are spatial differences in various top⁃
ics. The high-value areas of discussion on topics from the perspectives of life and management are mainly concentrated in
northeast China, while the discussion on topics from the perspective of production is concentrated in the Yangtze River Del⁃
ta, Pearl River Delta and other areas of south of the Qinling Mountains and Huaihe River; (4) In the process of public opin⁃
ion development, the processing trade-related industries and the tertiary industry are relatively sensitive to the dual control
policy of energy consumption. |
