关于股权结构对创业板上市公司绩效影响的计量分析

Econometric Analysis on the Influence of Stock Ownership Structure on the Performance of Listed Companies in Gem

随着公司在世界经济中的重要作用凸显,股权结构对公司绩效逐渐产生了不可替代的影响。鉴于上市公司为谋求上市而存在粉饰报表的可能性,本文随机选取了50家在创业板上市的2016年公司年报作为数据样本,根据股权集中度和股权属性研究股权结构对创业板上市公司绩效的影响。通过对变量的检测和统计,利用其特征变量的性质做回归分析,使其影响结果可以量化。分析结果显示:第一大股东持股比例与公司绩效呈负相关关系;管理层持股比例与公司绩效呈N型非线性关系;机构持股比例和Z指数与公司绩效呈正相关关系;流通股比例对公司绩效的影响呈倒U型结构。最后本文就上市公司绩效影响因素的结论数据分析结果,提出改善建议。
