Problematic applications of Necessary Condition Analysis (NCA) in tourism and hospitality research
本文评估了25篇使用必要条件分析（NCA）的旅游与酒店研究文章，发现多数存在对NCA必要性逻辑的误解或与fsQCA必要性分析的混淆，并建议遵循已发表的操作标准来改进应用。
The purpose of this note is to improve the application of Necessary Condition Analysis (NCA) in tourism and hospitality research by evaluating current applications. The field has rapidly adopted NCA for identifying necessary conditions in causal structures. An analysis of the 25 articles that use this emerging method reveals that most articles are problematic because they misinterpret NCA's necessity logic or do not recognize the difference between NCA's and fsQCA's necessity analyses. This situation can be easily revised by following published standards of good practice of conducting NCA.
