连锁董事网、关联方网与公司治理绩效的影响

企业所嵌入的连锁董事网或关联方网各自对企业治理绩效的重要作用已被广泛证实,但对于这两种网络交叉融合的情境下公司治理绩效的影响机理仍缺乏深入探索。基于此,利用沪深300指数中存在连锁董事网与关联方网交叉融合现象的独特样本,应用广义最小二乘回归方法,考察连锁董事网经由董事会规模和股权集中度两条路径对治理绩效的影响,以及双网融合度对其运作过程的调节作用。结果显示:连锁董事网主要通过影响股权集中度影响治理绩效,且当企业所处的双网融合程度更大时,连锁董事网对治理绩效的促进作用更显著。

Expansion of Edlen Equation based on cascade-correlation learning architecture

Due to the limitation of Edlen Equation to compensate for air refractivity in ordinary air pressure, an experiment to study the relationship between air refractivity and temperature, along with its pressure, is designed and carried out from ordinary pressure to low pressure. The expansion of Edlen Equation is achieved by using the cascade-Correlation learning method, and a neural network architecture model. The applied accuracy of neural network is the same as that of Edlen Equation in an ordinary pressure zone.
