| During the COVID-19 epidemic,the development of health insurance has attracted much attention.Because health insurance covering the responsibility of disease protection is an important part of the construction of China’s medical security system,it is necessary to give full play to the role of health insurance in this epidemic with a long time span and great influence,so as to ensure the health and life safety of residents.However,the operating efficiency of health insurance can reflect the operating level of health insurance in China to a certain extent,and it is a powerful index to judge whether health insurance can achieve high-quality development.Therefore,it is of great significance to study the operating efficiency of China’s health insurance under the influence of COVID-19 epidemic to achieve the goal of high-quality development of health insurance.Firstly,this paper introduces the research background and significance,then gives a brief overview of the research content,framework,innovation and shortcomings of this paper,and comments on the related research of health insurance operating efficiency.After that,it analyzes the current situation of China’s health insurance business,and constructs the mechanism of COVID-19 epidemic affecting health insurance from the cost and income of health insurance business.Then,based on the theory of technical efficiency and economies of scale,this paper selects DEA model with variable returns to scale to measure the operating efficiency of health insurance of 33 insurance companies of different scales,so as to replace the operating efficiency of health insurance in China.After the value of operating efficiency is obtained,the grey correlation method with less data restriction is used to explore the correlation between COVID-19 epidemic and operating efficiency of health insurance.At the same time,based on the perspective of COVID-19 epidemic situation,this paper adds the severity of epidemic situation into the indicators of influencing factors of health insurance operating efficiency,and explores the influencing factors of health insurance operating efficiency,which is an innovation in research indicators.Finally,according to the empirical results of this paper,some suggestions are put forward.The results show that the COVID-19 epidemic has a negative impact on the operating efficiency of health insurance in China.In 2020,when the epidemic happened,there was a big gap in the efficiency of health insurance among insurance companies of different scales in China,and the operating efficiency of high,medium and low-scale insurance companies showed a stepwise downward trend.At the same time,the scale effect of health insurance business is gradually disappearing,and the operating efficiency of health insurance industry is partly constant in scale returns,and partly decreasing in scale returns.However,the asset scale,labor input,expense ratio and investment return rate of the insurance company are the powerful factors that affect the company’s health insurance operating efficiency. |
