【摘要】：以2010—2014年滬深兩市主板A股432家民營(yíng)上市公司的平衡面板數(shù)據(jù)為樣本,運(yùn)用中介效應(yīng)研究方法,實(shí)證檢驗(yàn)了我國(guó)民營(yíng)上市公司中內(nèi)部控制質(zhì)量在股權(quán)集中度與公司績(jī)效關(guān)系中的中介作用。為保證研究的客觀性和穩(wěn)定性,分別用ROA和Tobin's Q對(duì)公司績(jī)效進(jìn)行衡量,采用Sobel Test法和偏差校正的非參數(shù)百分位Bootstrap法進(jìn)一步對(duì)中介效應(yīng)的顯著性進(jìn)行驗(yàn)證,并進(jìn)行了穩(wěn)健性檢驗(yàn)。研究結(jié)果表明:在我國(guó)民營(yíng)上市公司中,股權(quán)集中度和內(nèi)部控制質(zhì)量均對(duì)公司績(jī)效存在正向影響;股權(quán)集中度對(duì)內(nèi)部控制質(zhì)量存在正向影響;股權(quán)集中度對(duì)公司績(jī)效的影響有一部分是通過(guò)內(nèi)部控制質(zhì)量的中介作用實(shí)現(xiàn)的。研究結(jié)論在一定程度上揭示了民營(yíng)上市公司中股權(quán)集中度對(duì)公司績(jī)效產(chǎn)生作用的路徑,對(duì)提高公司治理水平和企業(yè)長(zhǎng)遠(yuǎn)價(jià)值具有實(shí)際意義。
[Abstract]:Based on the equilibrium panel data of 432 private listed companies in Shanghai and Shenzhen main Board from 2010 to 2014, the paper applies the method of intermediary effect research.The paper empirically examines the intermediary function of internal control quality in private listed companies in the relationship between ownership concentration and corporate performance.In order to ensure the objectivity and stability of the research, ROA and Tobin's Q were used to measure the performance of the company, and the Sobel Test method and the nonparametric percentile Bootstrap method were used to verify the significance of the intermediary effect, and the robustness test was carried out.The results show that: in China's private listed companies, both ownership concentration and internal control quality have a positive impact on corporate performance, equity concentration has a positive impact on internal control quality.The impact of ownership concentration on corporate performance is partly achieved through the intermediary role of internal control quality.To a certain extent, the research conclusions reveal the path of the effect of ownership concentration on corporate performance in private listed companies, and have practical significance for improving the level of corporate governance and the long-term value of enterprises.
