上市公司年报可读性30项指标2001-2025年

01、数据介绍

读取年报全文与MD&A 章节文本，去掉全部空白字符与目录引导点，按句末标点，切分句子（源文本按约30字硬换行，换行不是句读，不切）。然后jieba分词并只保留纯中文/英文词（含数字与标点的词一律丢弃），以「未登录词 + 词频低于 100 的低频词」构造难词比例，另出词长分布、虚词比例与词汇熵。最后用逐字笔画表（9574 字）与《通用规范汉字表》（8105 字，一/二/三级）算汉字难度，合成中文 Fog = 0.4×(平均句长_词 + 100×难词比例)。

覆盖 2001-2025 年 A 股上市公司年度报告，对整份年报全文与管理层讨论与分析（MD&A）章节两种文本分别测算篇幅、句法、词汇、汉字四组共 30 项可读性指标（两种口径合计 60 列），共 71926 条公司-年度观测、6091 家上市公司。

数据包括Python代码、测算结果。
