This study estimates the health care performance and the appropriate level of public health care sector using the data from 1980 to 2017 of 34 OECD countries. applying a panel analysis. The actual value of public health expenditure as a percentage of GDP in Korea is 4.4% in 2017, and the appropriate estimate ranges from 4.8% to 5.9% for each model, which shows Korea's share of public health expenditure as 0.4% ~ 1.5% lower than GDP. In other words, the share of public health expenditure as a percentage of GDP in Korea is low compared to the average share of public health expenditure in GDP in OECD countries. The proportion of actual public medical expenditure in Korea is 58.2%, and the appropriate estimates observed in OECD countries are 69.6% ~ 76.6%, which is 11.4 ~ 18.4% higher than actual value. Therefore, the share of public health expenditure in Korea is lower than that of OECD countries. In Korea, the share of inpatient beds in the public sector in 2017 is 9.9%. However, the average level of OECD countries is 16.1 ~ 38.1%, which is much higher than Korea. The difference shows a large gap from 6.3% to 28.3%. In general, when comparing the estimates and actual values of public hospitals, we can see that Korea is staying at a particularly low level. The number of inpatient hospital beds in Korea is 1.2 per 1000 population. The estimated number of inpatient beds in Korea is 3.7 ~ 5.9 based on the average concept of OECD countries. The difference is in the range of 2.5 ~ 4.7. The number of public inpatient beds per 1000 population was also lower than in OECD countries. The results of this study suggest that public health care such as the proportion of public health care expenditure and public sickness rates in Korea is much lower than that of OECD countries, but the proportion of public health care sector in Korea has been estimated within a few years It is practically impossible to reach the enemy politics. In addition, healthcare supply systems have long been developed on a historical, cultural and economic basis, so it should not be overlooked that it would be more inefficient to lift them to an artificial level. First of all, we will start by redefining the functions of the public health system, adjusting the priorities, and establishing a public health care system without linkage system. Based on the needs of the public health care and the needs of the government, It seems to be approaching.
