隨著21世紀全球化時代來臨，國與國之間交流頻繁，觀光成為二十一世紀的策略領航的產業之一。配合日本政府每年50兆日幣退休年金的釋出，日本退休銀髮族到海外進行長宿旅遊（Long Stay）漸成風潮，更是世界各地極力爭取的客群。 本研究以次級資料收集，消費者購買決策模式、消費者特性、知覺為基礎與文化的同異質性為中介，發現東南亞各國因異質文化，深受日本人喜愛。台灣因與日本同質性高，對於個性獨立、自主、語言能力強，喜歡挑戰者，知覺價值較低；但對於個性保守、知覺風險高者，因文化相近性可提高安全感，反而具吸引力。因此如何吸引不同消費者的興趣及認知，文化價值的創造，也成為推廣的重要因素。 本研究亦發現因消費者受個人、心理、社會、文化因素影響，對於長宿產品的需要與知覺也有所不同。特別是日本政府希望團塊世代留在日本長宿，刺激內需及協助農村發展，影響海外長宿夢想。台灣發展時應考慮如何影響日本退休族群的需求、解決心理及社會知覺壓力，進而影響購買決策。 結論針對購買決策模式、消費者特性、知覺價值與文化的同異質性進行方案建議，透過產品包裝及文化吸引力，政府的政策推廣，增加對台灣長宿產品的喜愛，希望能對台灣長宿事業有所助益。 Following the global era’s coming, traveling between countries to countries is more frequent than before.
