Quantitative Analysis of the Factors Influencing Macao's Tourism Industry: A Gray Correlation Approach

To provide a policy reference for promoting the development of Macao's tourism industry and for giving full play to the role of tourism in promoting Macao's economic development, the gray correlation analysis method was used to quantitatively analyze the data of Macao's tourism industry from 2010 to 2022, and the correlation degree and variation law between Macao's tourism development and various influencing factors were revealed from an empirical perspective. The gray correlation rankings of the influencing factors of the Macao tourism industry are as follows: travel agency income, hotel reception, commercial flights and helicopter sorties, gambling income, number of inbound passengers, number of inbound overnight passengers, cross-border car traffic, hotel occupancy rate, number of hotels above three stars, number of college students, catering industry income, hotel industry income, passenger flights, and exhibition industry income. In this regard, to promote the diversified and moderate development of Macao's economy, it is necessary to promote the integrated development of “tourism +”, cultivate tourism professionals, cultivate high-quality tourism intermediary enterprises, and promote the healthy development of Macao's tourism industry economy.
