摘要
本文以完成股权分置改革的778家上市公司为样本,实证检验了第一大股东控制力变化对公司绩效的影响,研究结果表明:①股改前,第一大股东控制力对公司绩效不存在显著性影响。股改后,第一大股东控制力与公司绩效存在"N型"曲线关系,但是这种"N型"曲线关系在经营绩效和公司价值上表现不稳定;②股改前,国有上市公司的第一大股东控制力与公司绩效之间关系不显著,非国有上市公司的第一大股东控制力对经营绩效影响不显著,而与公司价值存在"N型"曲线关系。股改后,国有上市公司的第一大股东控制力与经营绩效存在显著"N型"曲线关系,与公司价值存在显著线性关系,非国有上市公司的第一大股东与公司绩效存在显著"N型"曲线关系。
