Influenced by international economy and “the Extradition Law Protest” of Hong Kong，the spending of Macau’s tourists in 2019 dropped compared to last year. In the second half of 2019，the development of Macau’s tourism industry slowed down and tourists became less keen on visiting Macau. As the expenditure of tourists from the Chinese mainland sharply declined，the per-capita spending of tourists from overseas exceeded that from the Chinese mainland. The total spending of all tourists still decreased. While tourists expenditure on shopping decreased，tourists expenditure on accommodation and food and beverage relatively increased. Tourists from the Chinese mainland tended to buy luxuries，whereas overseas tourists preferred basic products. They felt more satisfied than before. In the face of the decrease in gaming revenue caused by COVID-19，the shared goal of government and enterprises is to boost tourists spending and Macau’s economic recovery and to overcome difficulties. In 2020，the Macau SAR government should rely on China’s policies，seeking more benefits from the Central People’s Government of China or accelerating the implementation of existing policies. The policies are as follows，to further open up Macau to Mainland residents，to shorten the visa process for mainland tourists visiting Macau，to facilitate customs clearance，to accelerate reform of customs clearance，etc. The Macau SAR government should take advantage of other cities in the Guangdong-Hong Kong-Macau Greater Bay Area to complement one another，attract more mainland tourists to visit Macau and revenge spending and revive Macau’s diversified economy.
