摘要

本研究对赞比亚国有企业和上市公司的公司治理实践和公司财务绩效进行了比较分析。利用2002年至2017年的横断面面板数据集,采用t检验统计量比较了非上市国有企业、上市国有企业和上市私营企业的公司治理实践和公司财务绩效。研究发现,赞比亚国有企业和上市公司的公司治理实践和公司财务绩效存在显著差异。上市公司的董事会规模在统计上显著低于国有企业,非执行董事在上市公司董事会中的比例也在统计上明显低于国有企业。另一方面,上市公司女性董事的比例在统计上显著高于非上市国有企业。在企业财务业绩方面,研究发现,上市私营企业的总资产回报率均值在统计上显著高于非上市国有企业的均值。在所有测量变量中都存在显著的效应大小。这是一项针对具体国家的研究,有助于了解国有企业和上市公司的公司治理实践和财务业绩。研究人员、公司治理从业者和政府决策者都对这些发现感兴趣。

Corporate Governance and Financial Performance of State-Owned Enterprises Compared to Listed Firms in Zambia: 2002-2017
The study was a comparative analysis of the corporate governance practices and firm financial performances between State-Owned Enterprises and listed firms in Zambia. Using a cross-sectional panel data set covering the period 2002 to 2017, the t-test statistic was employed to compare the corporate governance practices and firm financial performances between unlisted State-Owned Enterprises, listed State-Owned Enterprises and listed private firms. It was found that corparate governance practices and firm financial performances between State-Owned Enterprises and listed firms in Zambia were significantly different. The board sizes for listed firms were statistically significantly less than those of State-Owned Enterprises and the proportion of non-executive directors on the boards of listed firms were also statistically significantly less than those of State-Owned Enterprises. On the other hand the proportion of female directors on listed firms were statistically significantly more than those of unlisted State-Owned Enterprises. In terms of firm financial performance, it was found that the mean of the Return on Total Assets for listed private firms was statistically significantly greater than the mean for unlisted State-Owned Enterprises. There were significant effect sizes in all the measured variables. This was a country specific study that contributed to the empirical knowledge on corporate governance practices and financial performances in State-Owned Enterprises and listed firms. The findings are of interest to researchers, corporate governance practitioners and government policy makers.
