The study collects the historical data and related literatures of the water transportation about Danshui River and interviews many practical workers to induce 3 major dimensions and 17 criteria that affect the operation performanace of cruise industry. We employ Analytic Hierarchy Process (AHP) for analysis, and invite the experts of the related business, authorities and academic fields to evaluate the above dimensions and criteria in the prepared questionnaire. From the research results, it is found that the priority order of the 3 dimensions for improving the performance of cruise industry in Taipei City is “sailable channels’ conditions”, “tourist attraction”, and “service quality”. Besides, “sufficient depth of channel” and “daily regular sailing schedule” get the higher weights in the sailable channels condition dimension; In the tourist attraction dimension, “beautiful riverside scenery”, “rich human and cultural history”, and “the marketing and the promotion” are comparatively first three criteria; In the service quality dimension, the three critera: “regular sailing schedule”, “land transportation availability”, and “the information easily to obtain” have the higher importance. These findings are helpful in providing the municipal government to define clearly development policy on the blue highway and provide reference of the management strategy direction to the cruise industry of Taipei City for enhancing their operation performance.
