风险投资中的代理问题、风险分担与制度安排 总被引：11，自引：0，他引：11
信息不对称使得风险投资面临严重的代理问题，代理问题与风险企业（项目）的高不确定性又会导致风险投资的高失败率。恰当的制度安排能够降低代理成本和风险：一方面，风险投资家严格筛选高层管理团队，对他们采用强约束和适当的激励，并积极参与风险企业的管理，提供增值服务；另一方面，风险企业普遍采用全员持股这种组织激励方式。风险投资机制将监督、激励与风险分担有机地结合在一起，从而大大缓解了风险投资中的代理问题。论文还对我国风险投资业的发展提出一些相关建议。 相似文献

激励机制设计是现代企业理论的核心问题。在西方国家,以长期激励为主要特征的股票期权制度被认为是现代公司成功与发展的精髓。我国的国有企业由于缺乏长期的激励机制,代理问题非常突出。为激励并约束国有企业经营者,引入股票期权制度势在必然。然而,无论在理论上还是在实践上,股票期权制度在我国还处于起步阶段,因此有必要借鉴国外成熟的经验,修订、完善相关的法律法规,引导和规范股票期权制度的实践。 相似文献

经理股票期权:有效率的激励制度 总被引：1，自引：0，他引：1
企业经营者是我国十分稀缺的人力资源，长期以来通过若干种激励方式想调动其积极性，但效果均不理想。因此寻求并建立一种有效率的激励机制成为当务之急。本文认为：经理股票期权激励（ESO）不失为解决此问题的一种有效形式，它最大优点是将所有者与企业经营者的利益捆绑在一起，强调共同的长期利益。文章就此形式进行了多方面的阐述，并结合当前实施的具体情况提出了自己的一些建议。 相似文献

Spacecraft output feedback attitude control based on extended state observer and adaptive dynamic programming 总被引：1，自引：0，他引：1
This paper investigates spacecraft output feedback attitude control problem based on extended state observer (ESO) and adaptive dynamic programming (ADP) approach. For the plant described by the unit quaternion, an ESO is first presented in view of the property of the attitude motion, and the norm constraint on the unit quaternion can be satisfied theoretically. The practical convergence proof of the developed ESO is illustrated by change of coordinates. Then, the controller is designed with an involvement of two parts: the basic part and the supplementary part. For the basic part, a proportional-derivative control law is designed. For the supplementary part, an ADP method called action-dependent heuristic dynamic programming (ADHDP) is adopted, which provides a supplementary control action according to the differences between the actual and the desired system signals. Simulation studies validate the effectiveness of the proposed scheme. 相似文献

In this paper, we consider output tracking for a class of MIMO nonlinear systems which are composed of coupled subsystems with vast mismatched uncertainties. First, all uncertainties influencing the performance of controlled outputs, which include internal unmodelled dynamics, external disturbances, and uncertain nonlinear interactions between subsystems, are refined into the total disturbance in the control channels of subsystems. The total disturbance is shown to be sufficiently reflected in the measured output of each subsystem so that it can be estimated in real time by an extended state observer (ESO) in terms of the measured outputs. Second, we decouple approximately the MIMO systems by cancelling the total disturbance based on ESO estimation so that each subsystem becomes approximately independent linear time invariant one without uncertainty and interaction with other subsystems. Finally, we design an ESO based output feedback for each subsystem separately to ensure that the closed-loop state is bounded, and the closed-loop output of each subsystem tracks practically a given reference signal. This is completely in comply with the spirit of active disturbance rejection control (ADRC). Some numerical simulations are presented to demonstrate the effectiveness of the proposed output feedback control scheme. 相似文献

本文选取2006-2010年我国中小企业板上市公司作为样本,构造一种面板数据结构,实证考察了高管团队认知多样性对创业战略导向的影响,以及公司股权结构(股权集中度和股权制衡度)的调节效应。实证结果表明,除高管团队教育背景多样性外,高管团队年龄多样性和任职经历多样性均会对创业战略导向产生显著正向影响。进一步地,股权集中度对高管团队年龄和任职经历多样性具有显著负向影响,股权制衡度则对两者变量产生了显著正向影响,但两者均未对高管团队教育背景多样性产生显著影响;高管团队年龄多样性和任职经历多样性与创业战略导向关系受到了股权集中度的显著负向调节效应,却受到股权制衡度的显著正向调节效应,不过两者均未能对高管团队教育背景多样性与创业战略导向关系产生显著调节效应。本文研究结论对于公司股权结构优化、高管团队建设以及创业战略导向设计等方面具有积极的启示作用。 相似文献

In this paper, active disturbance rejection control (ADRC) based on a neural network has been investigated for the attitude control of the hypersonic vehicle (HV) with uncertain disturbances, which are regarded as a strongly time-varying, nonlinear, and coupled system. The structure of nonlinear state error feedback (NLSEF) with an Extended State Observer (NLSEF+ESO) utilized in ADRC is considered to have good disturbance resistance ability in engineering applications with less dependence on the mathematical model of the system. However, the strong coupling of the HV makes it complicated to separately design ADRC for each channel. In addition, the bandwidth and parameters of the ESO can seriously affect the performance of the ADRC, while jitter occurs when they are not well matched. A cascade active-rejection control scheme is designed by introducing the Radial Basis Function (RBF) Neural Network to substitute the ESO in ADRC, which mitigates the shortcoming of ADRC in addressing the control problems of the MIMO system with coupling disturbances. The NNESO can adapt well to disturbance characteristics through online training and fitting and can effectively reduce the jitter of the control. The stability of the NNESO is proved by Lyapunov stability theory, and the numerical simulations are presented to demonstrate the effectiveness of our theoretical results. In summary, the proposed NNESO-based cascade ADRC is an effective method for solving the problem of HV control with better disturbance resistance. 相似文献

The swing temperature usually leads to the parameter drift and even failure in Electric power steering (EPS), which is a potential threat for safe driving of automobiles. Power Metal-Oxide-Semiconductor Field Effect Transistors (MOSFET) are a primary heat source in EPS and, therefore, can directly represent the temperature fluctuation of EPS. Existing technologies that observe the temperatures of MOSFETs are restricted by operating conditions, cost and implementation difficulty for application in automotive EPS systems. To address this issue, a novel real-time junction temperature observation method is proposed by combining a Foster network with an Extended State Observer (ESO) technique. Transfer paths of thermal resistance in EPS converters are analyzed, and the thermal state space model is established by the Foster network. The temperature ESO of the EPS controller is then developed based on this thermal model to estimate the temperature and perturbation. Confirmation tests that introduce a simulated driving steering method measure the MOSFET temperature and verify the validity of the temperature ESO. The test results demonstrate that the proposed temperature ESO can be used to monitor junction temperatures of MOSFETs in EPS. 相似文献

Taiwan has made significant progress in the semiconductor industry with government agencies and bureaucrats as the driving forces over the past 30 years. Taiwan's impressive achievement in the semiconductor industry clearly indicates that the government failures and agency problem usually associated with deep government involvement did not occur in Taiwan. Why is that the case? This paper proposes a principal-agent framework for technology policy and applies the framework to discuss the institutional arrangements through which bureaucrats were controlled effectively in executing the semiconductor industry policies in Taiwan. By analyzing the institutional and organizational arrangements Taiwanese leaders made to mitigate the agency problem, this paper brings bureaucrats into the popular developmental state theory and emphasizes that the success of state intervention should not be taken for granted, and it also brings politics into technology policy analysis and stresses the importance and complexity of agency problem in technology policy. 相似文献

我国专利"数量大、质量差"的问题日趋显著,学术界和产业界已经逐步重视专利代理服务对科技创新的重要支撑作用,但是如何针对专利质量的提升确立专利代理服务标准和模式这一问题尚没有得到充分论证和清晰解答。在相关文献研究的基础上进行了实证研究,逐一验证了专利代理人胜任特征对专利技术质量和专利申请质量影响的假设命题,进而量化了专利代理人各胜任特征对专利质量的影响程度及路径。研究结果表明,专利代理人的知识结构、职业能力、业务素养、个人品质、发展动机等特征对专利技术质量存在显著正向影响;技能经验、知识结构、社交能力、业务素养、外语技能、职业素养等特征对专利申请质量存在显著正向影响。专利代理人胜任特征与专利质量之间关系的研究有助于引导专利代理行业标准的制定、人员等级的划分以及相关政策的制定,并且为现阶段解决我国专利质量现实问题的政策措施实施提供理论依据。 相似文献
