Abstract
This study examines the relationship between Taiwan’s most popular
attractions and inbound tourist arrivals, using night-market–related keywords
as a case in point. Leveraging high-frequency Google Trends data, we use search
intensity for night-market keywords to forecast lower-frequency inbound
arrivals, with the aim of improving prediction accuracy by exploiting timely
information. We construct a composite night-market search index via principal
component analysis (PCA) and assess its interrelationship with inbound arrivals
to identify which keywords are most closely associated with tourism demand. The
contributions are threefold: (1) the empirical results robustly show that
inbound tourist arrivals are significantly affected by night-market keyword
searches; (2) the statistically significant keyword “Shilin Night Market”
aligns with actual search behavior, confirming its prominence among
international visitors; and (3) to our knowledge, this is the first study to
directly analyze the effect of night-market–related online search
activity on inbound tourism to Taiwan, thereby filling a gap in the literature.
Our findings also reflect the policy context in which night-market branding has
been promoted by local governments and private initiatives over the past two
decades, suggesting that place-based tourism marketing has effectively
stimulated inbound demand and, in turn, intensified related search activity.
