(12) Since the existence of human society, the risk of natural disasters has been one of the important risks with great influence. The complexity of natural disaster risk causes, the influence of results and the persistence of influence increase the difficulty of natural disaster risk management. Although the traditional risk management theory provides a variety of risk disposal methods for all kinds of risks, such as retention, loss control, loss financing and so on. How to distinguish the types of natural disaster risks from the economic level and how to choose the corresponding risk management tools according to the unique nature of risks is still a complex topic. Recommended reading Insurance Weekly: The H-share listing of Xinhua Life Insurance plummeted by 9.82%. The China Insurance Regulatory Commission criticized 14, and the life insurance funds of insurance companies will exceed 20 billion yuan. The state encourages institutions to develop fresh agricultural products insurance 1 month. Non-Beijing employees in Beijing should be included in the development strategy of maternity insurance-suggestions for the new chairman of the China Insurance Regulatory Commission. The diversity of natural environment in China has created a more complicated natural disaster risk environment, and the more special national condition is that China is still in the process of industrialization and is coping with it. In the past 20 years, consistent with the evolution trend of natural disaster risk in the world, the intensity of natural disasters in China has also increased, the frequency of extraordinarily serious natural disasters has increased, and the increase of risk carriers has led to a high loss index of natural disasters. The suddenness and unpredictability of natural disasters indicate that China is very likely to suffer major natural disasters in individual years, which poses a considerable threat to the stable development of the overall macro-economy. In this context, it is more practical for China to make rational use of existing economic resources, control and finance losses under the dual constraints of economic and natural conditions, and build an optimal combination of risk management methods. The book "Research on Natural Disaster Risk Management" published by China Commercial Press is an attempt to establish a systematic and complete natural disaster risk management system. Based on the research background, this book identifies and measures the risks of natural disasters, and demonstrates in detail the best division of labor and implementation path of diversified natural disaster risk management strategies with the natural disaster insurance system as the core through model construction. For the improving natural disaster risk management system, the enlightenment brought by this book mainly includes the following points: proceeding from reality, using the expected utility analysis framework, the optimal demand of natural disaster insurance is studied as an important way of loss financing. Insurance is the product of intermediation and specialization of risk management, which mostly involves the game between supply and demand. Firstly, the author analyzes the development of China's natural disaster insurance system and the current supply and demand background, and lists the main problems existing in this system: 1. The reasonable competition pattern has not yet been formed, and insurance operators tend to provide homogeneous insurance products with traditional advantages, lacking underwriting motivation for the risk targets exposed by different natural disasters, and unable to meet the demand of market differentiation. 2. The price of insurance products is not really marketized, which affects the ability of insurance subjects to prevent risks through price leverage and restricts the expansion of natural disaster risk protection. 3. Agricultural insurance, which has the greatest impact on the risk of natural disasters, lacks systematic and continuous policy support, and lacks clear response and insurance system construction ideas for catastrophic risks such as earthquakes and floods. Facing the current situation that the natural disaster risk guarantee system is not sufficient, the author constructs the insurance demand model under the natural disaster risk environment by using the expected utility analysis framework. The model analysis shows that when most uninsurable natural disaster risks are closely related to insurable natural disaster risks, or positively related in a long period of time, the direct consequence is that the limited insurance supply cannot meet the excessive demand of risk subjects for natural disaster insurance, whether it is the related effect or preference effect of risks or the improvement of price leverage sensitivity caused by it. In the case that the compensation limit of unit policy cannot exceed the actual value of assets, this will form a deformed market, that is, excess demand will lead to an increase in insurance rates, which will further curb insurance demand and erode the conventional natural disaster insurance mechanism. On the basis of demand analysis, the book further establishes the insurance pricing model of subsidies, and then discusses the possibility of extending insurance supply through government subsidies. The analysis of supply model shows that when there are subsidies positively related to insurable risks, the solvency of insurance companies is easy to maintain at the statutory standard, and subsidies can have a negative effect on insurance prices, that is, they have a positive effect on insurance supply, regardless of the market environment. The difference is that under the condition of marketization of insurance prices, it is more suitable to directly subsidize the compensation results and hedge risks; When the insurance price is determined externally, it is more suitable to subsidize the purchase price of consumers and hedge risks. China is in the process of changing the insurance price from external decision to market decision. While maintaining the stability and continuity of subsidies, we should also maintain the flexibility of subsidy forms, that is, make corresponding adjustments according to changes in the market environment. On this basis, the author suggests expanding the insurance supply through subsidies and other means, expanding as many natural disaster risks as possible into insurable risks, and resolving the negative impact of insufficient natural disaster insurance on the operation of the conventional insurance market. In this process, it is necessary to give full play to economic leverage, expand the coverage of commercial insurance system to natural disasters, and strengthen institutional support to develop government-led catastrophe insurance system. This paper studies the interaction among natural disaster insurance system, disaster prevention and mitigation mechanism and financial market by using the comprehensive risk management analysis framework. In the process of establishing natural disaster insurance system, we should also pay attention to the organic combination of insurance mechanism, disaster prevention and mitigation mechanism and structured catastrophe financial products. The research shows that when the risk of natural disasters affects a large range, the loss control measures of micro-subjects have an alternative function. Therefore, it is very important to encourage micro-subjects to effectively prevent and control natural disaster risks through compulsory insurance and other forms. In addition, it is necessary to improve the natural disaster risk information support system and information sharing mechanism to provide technical support for the insurance industry and the whole society in disaster prevention and mitigation. For insurers, it is necessary to design insurance products reasonably to prevent the moral hazard of the insured and ensure the effect of natural disaster risk prevention and control. At the same time, the research shows that the development of China's capital market and derivatives market has expanded the capacity and ability of financial markets to withstand natural disaster risks, and the birth of standardized derivatives tools based on virtual index also means that China basically has the institutional and technical conditions to design catastrophe tools; At the same time, China investors also need to introduce new financial instruments with relatively independent returns, so as to spread the overall risk of the portfolio. In this context, it is necessary to develop catastrophe swaps, catastrophe bonds, catastrophe futures, catastrophe options and other derivatives based on insurance transactions or reinsurance transactions. It is particularly important to note that structural catastrophe products are typical cross-cutting products, so it is increasingly important to establish a comprehensive concept of financial supervision and strengthen the cooperation and coordination mechanism between insurance market supervision and financial market supervision.
