This social phenomenon can bring many opportunities for the future development of our state-owned enterprises. An important opportunity for the rapid development of China's state-owned enterprises is to build a unique competitive advantage from the internal system. In this development process, internal system control plays a very key leading role. Before that, we formulated new requirements and standards. Actively adapt to the development trend of the times, adapt to the increasingly strict management requirements, the focus of contract management of state-owned enterprises gradually turned to analyze the existing problems and specific preventive measures. At the same time, since most companies operate in accordance with the law, the more effective the contract management is, the fewer economic disputes will be, and the better the long-term development of the company will be. Under this background, it is of great macro-realistic significance to study some problems in the current labor contract risk management of state-owned enterprises and relevant preventive measures.展开更多

文摘The aversion order is a way of ordering of risks. Is there the optimal in aversion order in reinsurance contracts of reinsurance？ This paper discusses these objects and gives some optimal reinsurance contracts in certain sets of feasible reinsurance contracts.
