Data on ESG disclosure and corporate overleveraging

=This study employed data from Chinese listed non-financial companies from 2013 to 2022 to explore whether environmental, social, and governance (ESG) disclosures reduce corporate over-leveraging and the impact of economic policy uncertainty on this relationship.
All data are obtained from the China stock market and accounting research (CSMAR: https://data.csmar.com/), wind database (https://www.wind.com.cn/portal/en/EDB/index.html) and the policy uncertainty website (https://www.policyuncertainty.com/scmp_monthly.html). This study eliminates all records with missing values and used 1% and 99% tail-cutting methods to address extreme values in the data. Consequently, 12,869 sample data points are obtained.

本研究选取2013至2022年中国非金融类上市公司数据，旨在探究环境、社会和治理（ESG）披露能否抑制企业过度杠杆行为，以及经济政策不确定性对该关系的影响。
所有数据均取自中国股票市场与会计研究数据库（CSMAR：https://data.csmar.com/）、万得数据库（Wind：https://www.wind.com.cn/portal/en/EDB/index.html）以及政策不确定性网站（https://www.policyuncertainty.com/scmp_monthly.html）。本研究剔除所有存在缺失值的记录，并采用1%与99%缩尾处理方法处理数据中的极端值，最终得到12869条有效样本观测值。
