Knowledge Graph of China's Executive Compensation Gap:Visual Analysis Based on CiteSpace

This study selected 473 local research articles on executive compensation from core journals in the China Academic Journals(CNKI)full-text database and the Chinese Social Sciences Citation Index(CSSCI)from 2003 to 2020.Then,the bibliometric analysis method was adopted and conducted in regard to the number of articles published,authors,research institutions,high-frequency keywords,etc.In view of the increasing studies of this field,this study showed that a few scholars and institutions with high academic influence have been involved in the research on executive compensation gap in China.The results from this study revealed that the research on the relationship between executive compensation gap and firm performance as well as the moderating variables between them were topics of interests.In the context of the increasing compensation gap which had become a global interest,the research on management power and promotion incentives have established their significance as important research frontiers.

A Study on the Compensation Gap among Executives at Chinese Enterprises

Based on data for 2005 to 2012, an analysis of the compensation gap between top executives at different Chinese listed companies reveals the following conclusions. （1） The large compensation gap existing among executives at listed Chinese companies--in some years even larger than that between rank-and-file employees--is mainly caused by the exorbitant executive compensation at a minority of companies. （2） Between 2005 and 2012, the compensation gap first widened dramatically and then diminished gradually. The leading factor in this fluctuation was the drastic rise and fall in the level of executive compensation at a handful of financial enterprises. The main reason for the narrowing of the compensation gap is central government regulation, which has helped to curb the excessive growth of executive compensation in society as a whole. （3） Even in the same round of fluctuation, state-owned listed companies differ markedly from non-state-owned listed companies in the way their executive compensation is decided. （4） State-owned listed companies＇ executive compensation strategies and their internal governance structure have not played their due role in moderating the overly rapid growth of their executives＇ compensation or in reducing the compensation gap.

Control strategy for multiple capsule robots in intestine

Based on the critical gap phenomenon of the intestinal capsule robot,a variable-diameter capsule robot with radial gap self-compensation is developed in this paper.With the functional variation principle,a fluid dynamic pressure model satisfying the boundary conditions of the outer surface of capsule robot with screw blades is derived.The critical gap phenomenon is studied theoretically and experimentally based on the end effect and the dynamic balance characteristics of the fluid on the surface of capsule robot.The concept of start-up rotation speed is defined,the relationship between the start-up rotation speed and the spiral parameters of capsule robot is investigated.The strategy for implementing drive and control on several capsule robots under the same rotational magnetic field is proposed,and by defining the start-up curves of several capsule robots with the similar motion regulation as the objective functions,genetic algorithm is employed to optimize the spiral parameters of several capsule robots.Experiments have shown that the proposed drive and control strategy for several capsule robots can be implemented effectively.It has a good prospect of application inside intestine to realize the drive and control on several capsule robots for different medical purposes.
