From 2018 to 2019，Taiwan’s tourism administration departments continued to promote the development of diversified tourist source markets，smart tourism and other development strategies，to increase policies and subsidies，and to implement the new policy of southward-tourism，but the effectivenessis limited. Taiwan’s tourism output growth is slow. In 2018，the total number of inbound tourists increased by 3 percent，and the mainland tourists remained to be the largest source of inbound tourists. The total amount of outbound tourists increased，and the total number of visitors and expenses of Taiwan residents both fell. Due to the impact of political factors in the island，the number of mainland tourists decreased sharply from 2018 to September 2019，which greatly affected the development of Taiwan’s tourism industry. Taiwan’s tourism industry is waiting for development opportunities. Under such conditions，relevant departments in Taiwan have taken measures to focus on promoting inhabitants’ tourism within the island.
