高管纵向联结是公司治理实践中被广泛应用的一种治理机制,学术界一直存在对其成因进行探索的呼吁。基于公司治理理论,应用定性比较分析方法(QCA)整合了涉及上市公司内外部治理制度的多个变量,探讨了促成高管纵向联结现象的多重并发机制,得出以下结论:(1)高管纵向联结现象存在三类驱动路径,分别是因母公司对管理层赋能需求导致的赋能控制型、因明晰权力划分需要导致的权力协调型、因母公司监督意识增强导致的强化督导型。(2)在各路径中,内外部治理机制之间是互补关系而非替代关系,单纯的内部治理或外部治理机制组合都不是导致高管纵向联结的充分条件。(3)母子公司高管非纵向联结的驱动机制分为两条路径,且与高管纵向联结的驱动机制存在非对称因果关系。研究结论有助于学术界深化对高管纵向联结现象的认识,也能够为企业集团优化治理结构提供借鉴。

As a microforming technique, micro/nano-structural replication possesses advantages of high precision and efficiency. With the remarkable superplasticity in the supercooled liquid region, amorphous alloys or metallic glasses(MGs) are regarded as ideal materials for miniature fabrication. However, due to the intrinsic metastable nature of supercooled liquids, the design of imprinting processes for MGs poses a challenge. In the past, process parameters have largely relied on trial-and-error *** this work, a low-frequency active force modulation system is employed to apply a stable, precise, and real-time feedback stress field for imprinting of MG samples. Low-frequency vibrations can facilitate the filling of microstructures on the template surface by reducing the effective viscosity of the supercooled liquid. With the dataset composed of orthogonal experiments, a machine learning strategy based on back-propagation(BP) neural networks was utilized to construct a 3D parameter space for temperature, stress, and time, and to predict the corresponding filling ratio. Furthermore, the optimal combination of imprinting process parameters was identified, and its filling ratio was experimentally validated to reach as high as 0.94. The near-perfect replication of microstructures confirms the superiority of the active force modulation system and the data-driven strategy of machine learning-assisted parameter design. At the same time, this one-step microforming process provides a new approach to addressing the accuracy-cost trade-off dilemma in precision manufacturing.
