In this situation, the dual ownership structure arises at the historic moment and becomes a powerful weapon for the founders to control. In order to maintain the right of control, most enterprises have chosen the typical structure of the dual ownership system-AB share system, and Alibaba Group has established an upgraded version of the dual ownership structure-partner system in view of its own development characteristics. This paper uses the method of case study, taking Alibaba Group as an example, from the perspective of control rights protection to study the Alibaba partnership system in depth. On the basis of combing and analyzing the protection mechanism of Alibaba's control rights, this paper further compares the AB share system with the partner system, sums up the advantages and limitations of the partner system, and puts forward some relevant solutions. This paper will provide some reference for the research on the dual ownership structure of Chinese Internet companies.展开更多

Based on rights formulated by acts and regulations, this paper establishes models of arrangement for corporate rights of control, and then analyses the composite basic features derived from the models. To conclude, a main frame for the arrangement and innovation of corporate rights of control is put forward based on the real practice of listed companies in China.展开更多
In this paper, for the delay control system: (x) over dot (t)=f[x(t), x(t-1), u(t), t] t is an element of[t(0), t(1)] x(t)=psi(t) t is an element of[t(0), t(1)] with state right endpoint restricted by condition psi(k)...In this paper, for the delay control system: (x) over dot (t)=f[x(t), x(t-1), u(t), t] t is an element of[t(0), t(1)] x(t)=psi(t) t is an element of[t(0), t(1)] with state right endpoint restricted by condition psi(k)[x(t(1))]=0 (k=1,2,..., l) a maximum principle is given. And as a specific example, this paper gives a maximum principle under the condition that partial stares right endpoints be completely fixed. Finally, this paper gives an example to explain the application of the main result of this paper. All the results are suitable for the control systems with multidelay as well.展开更多
为应对数字版权管理中恶意发布者的挑战,提出一种可撤销访问控制加密(Revocable Identity-based Access Control Encryption,RACE)方案。RACE结合结构保持签名、非交互式零知识证明和抗碰撞聚合器,通过可净化的身份基广播加密,确保合法...为应对数字版权管理中恶意发布者的挑战,提出一种可撤销访问控制加密(Revocable Identity-based Access Control Encryption,RACE)方案。RACE结合结构保持签名、非交互式零知识证明和抗碰撞聚合器,通过可净化的身份基广播加密,确保合法发送方传输的密文经净化器处理后与原始密文格式一致。同时,引入撤销机制,通过更新密钥实现用户撤销与密文更新以增强系统的安全性。安全性分析表明,RACE满足“无读”和“无写”规则的安全要求。性能分析表明,RACE在增加安全功能的同时,实现了较低的计算和通信开销,其中解密阶段的计算开销较现有高效方案降低约12%,性能表现良好。展开更多
