基于国有上市公司国有股一股独大产生的“内部人控制”,国有上市公司的绩效应当低于民营上市公司。然而另一种竞争性假说是民营上市公司存在治理上的缺陷,容易导致大股东侵占中小股东利益的现象发生,进而推论民营上市公司的低绩效。本文以我国资本市场制度背景为依据,提出“民营上市公司绩效在总体上优于国有上市公司”的理论假设,并用民营上市公司与国有上市公司的财务数据对上述假设作实证检验。研究总体结论是民营上市公司盈利能力、资产负债率显着高于国有上市公司,但利润分配少,利润质量没有显着差异。本文试图结合中国资本市场实际对这些现象进行解释。
Based on "internal person control" derived from state-owned listed companies, some literatures argue that comparing to the state-owned listed companies, the performance of private-controlled listed companies should be better. Other literatures, from perspective of large shareholder expropriation, argue that the private ones may indicate low performance. This paper, based on institution background of Chinese capital market, puts forward a reasonable hypothesis. An empirical test will be done to test the hypothesis.
