Tourism is an important industry in most countries, and is a star industry in the twenty-first century. Tourism can create many jobs and earn much foreign exchange. Tourists generally decide to tour depending on their psychology and self-perception. This research modifies Ajzen's theory of planned behavior and constructs a model of Kinmen tourists' behavioral tendencies. The data to test the cross-validity of the Kinmen tourists' behavioral tendencies model by structural equation modeling is investigated for the years 2001 and 2002. To test cross-validity by SEM for these two group samples, this research provides insight into these differences and implications for tourism management.
