The number of visitor to Macao reaches a new record in 2018，growing over 9.8% compared to 2017. Mainland China，Hong Kong and Taiwan region still stood as Macao’s top three visitor source markets. Visitors to Macao have risen by 13.8%. Visitors from Hong Kong have risen by 2.6% and visitors from Taiwan region have risen slightly by 0.1%. After the surging of 2017，international visitor to Macao declined about 1.1% and comprised about 8.7% of the total visitors. Although the percentage of overnight visitors is still higher than that of same-day visitors in 2018（52% vs. 48%），the growth rate of same-day visitor arrivals is significantly higher than that of overnight visitors（12.7% vs. 7.2%）. At the same time，the average length of stay is similar to last year，standing at 1.2 days for all visitors. In view of the incensement of the number of visitors and its adverse impact on visitors and residents，Macao should pay much attention to its Tourism Carrying Capacity，and take measures to attract high value visitors and Individual Visit Scheme guests. Some other issues such as exploring the impact of the Hong Kong-Zhuhai-Macao Bridge on the visitor structure of Macao and accelerating the development of smart tourism also should be considered carefully.
