摘 要
自 2007 年股权分置改革基本完成开始,种种因素引致我国证券市场大股东
减持热潮持续升温。大股东的减持行为一直被视为是市场波动的重要原因之一,
因此本文在解释股权分置等概念、梳理处置效应等理论的基础上,选取搜集了
2007 年 1 月至 2020 年 12 月 A 股天然气板块符合筛选条件的 56 家公司全部减持
数据。用实证研究的方法,从股权结构、资本结构、财务绩效水平三个角度设置
多个解释变量,进行相关性分析、多重共线性分析和回归分析,以研究 A 股天然
气公司大股东减持的影响因素。根据回归结果分析得出结论:第一大股东持股比
例越高时,大股东减持比例越低;股权制衡度越高时,减持比例越高;资产负债
率越高时,大股东减持比例越高;权益乘数越高时,大股东减持比例越高;
Basic EPS 越高时,大股东减持比例越低;市盈率PE 越高时,大股东减持比例
越高;净资产收益率 ROE 越高时,大股东减持比例越低;流动比率越高时,大股
东减持比例越低;营运周期越长时,大股东减持比例越高;对于国有背景公司,
大股东减持比例会较低;在宏观经济情况上行时,大股东减持比例较低。最终在
分析结果的基础上,从四个角度提出对大股东减持影响因素的应对建议:灵活制
定政策严格执行监管、提升投资者素养、投资者的分析和应对、加强信息披露的
有效性充分性。
关 键 词:大股东;大股东减持;A 股天然气板块;影响因素

I ABSTRACT
ABSTRACT
Since the split share structure reform was basically completed in 2007, various
factors have led to the upsurge of reducing the holdings of major shareholders in
China;s securities market. The reduction of major shareholders has always been
regarded as one of the important reasons for market fluctuations. Therefore, based on
explaining the concepts of split share structure and combing the theory of disposal
effect, this paper selects and collects all the reduction data of 56 companies in the A-
share natural gas sector that meet the screening conditions from January 2007 to
December 2020. Using the method of empirical research, multiple explanatory
variables are set from the perspectives of ownership structure, capital structure and
financial performance level, and correlation analysis, multicollinearity analysis and
regression analysis are carried out to study the influencing factors of the reduction of
major shareholders of A-share natural gas companies. According to the analysis of
regression results, it is concluded that the higher the shareholding proportion of the
first largest shareholder, the lower the reduction proportion of the largest shareholder;
The higher the degree of equity balance, the higher the proportion of reduction; The
higher the asset liability ratio, the higher the reduction proportion of major
shareholders; The higher the equity multiplier, the higher the reduction proportion of
major shareholders; The higher the basic EPS, the lower the reduction proportion of
major shareholders; The higher the PE ratio, the higher the reduction proportion of
major shareholders; The higher the roe, the lower the reduction proportion of major
shareholders; The higher the current ratio, the lower the reduction proportion of major
shareholders; The longer the operation cycle, the higher the reduction proportion of
major shareholders; For companies with state-owned background, the reduction
proportion of major shareholders will be low; When the macroeconomic situation goes
up, the reduction proportion of major shareholders is low. Finally, on the basis of the
analysis results, this paper puts forward countermeasures to the influencing factors of
the reduction of major shareholders from four angles: flexible formulation of policies,
strict implementation of supervision, improvement of investor literacy, analysis and ABSTRACT
response of investors, and strengthening the effectiveness and sufficiency of
information disclosure.
