We use the data of the Chinese growth enterprises market (GME) listed high-tech firms from 2016 to 2022 as a dynamic panel data model with the system-generalized method of moments (sys-GMM), adopting return on asset and earning per share as firm performance. Our results show that capital ...
摘要:以2002～2011 年716 家上市公司为样本,运用动态面板的System GMM 估计方法,同时考虑了三种内生性,研 究了管理者薪酬、薪酬绩效敏感性与公司非效率投资间的关系。通过研究发现,提高管理者薪酬及其薪酬绩效敏感性不仅有利 于降低公司的非效率投资行为,而且管理者薪酬与其薪酬绩效敏感性间的交互效应也对公司非效率...

By using the system generalized method of moments (system GMM) model and other panel estimation models to generate regression results, it is found that environmental regulation exhibits a U-shaped nonlinear influence on green growth; as the intensity of environmental regulations increases, there is ...

do anyone know or have a Stata procedure for applying the System-GMM by Blundell and Bond on a dynamic panel data model? Thank you all, Stefano Iezzi At 17.29 24/04/2003 -0500, Scott Merryman wrote: --- Original Message --- From: ...
To get the feature coefficients of higher priority, further processing parameters are needed, and Gaussian mixture model (GMM) is used to describe the spatial distribution of the linear prediction coefficient cepstrum [20], and the formula expression of the style feature vector is obtained: (3)...
For nonlinear analyses, VCDs were modeled using a spring element to simulate the connection stiffness in series with a generalized Maxwell model (GMM) which consists of one spring element in parallel with two Maxwell elements (spring and dashpot in series). The GMM is capable of simulating frequ...
