Although Singapore, South Korea and Japan have controlled the epidemic in time, their economies will definitely be affected. First of all, the epidemic has affected the tourism economy of various countries. During the golden tourist period of the Spring Festival, because China is the main tourist force of all countries, the number of people traveling to these three places has been greatly reduced due to the epidemic. Secondly, the epidemic has affected people's consumption psychology, and people will save the number of trips and consumption, except for the necessary hoarding of goods, which is very unfavorable to the development of the real industry. On the other hand, it also affects the export of goods. Many places have blocked cities and factories have stopped producing goods, which will also lead to the decline of the local economy.

This new coronavirus will have an impact on the economies of all countries. People divide or stop going to school to control the epidemic, which will lead to the production activities in various countries can not be carried out normally, followed by people's nervousness about cash, so the stock market fell and gold fell. In difficult times, people can only get rid of their nervousness by withdrawing funds. However, it also increases the performance of retail industries such as supermarkets, and in contrast, it causes losses in entertainment industries such as film industry.

the impact of the epidemic has caused countries to lose a lot of fiscal revenue. For these three countries, tourism is one of the fiscal revenues, but because of the outbreak of the epidemic during the Spring Festival in China, tourists can't travel abroad, which makes the three countries lose a lot of fiscal revenue from tourism.

In fact, this epidemic will bring economic challenges to the whole world. Because people can't carry out normal production activities to control the epidemic, and the epidemic has not been completely controlled in the world at present, so I can also predict that the global economy in the first half of the year must be very bad. For these three countries, being able to control the epidemic means that the loss is much less than others, and Japan has the most loss. Because it can't hold the Olympic Games on time, Japan will lose as much as 3.2 trillion yen.
