基于Mill&Morrison的旅游系统理论,文章构建了由6个主类和61个亚类组成的旅游研究系统分类框架(The tourism research system categorization framework),选取31本国际旅游期刊在2003—2012年期间的10058篇文章,从而提取出13669个...基于Mill&Morrison的旅游系统理论,文章构建了由6个主类和61个亚类组成的旅游研究系统分类框架(The tourism research system categorization framework),选取31本国际旅游期刊在2003—2012年期间的10058篇文章,从而提取出13669个关键词(其出现频次为41624)并进行归类,运用演绎分析和统计方法对旅游研究主题进行大数据整理。文章识别出旅游学研究的跨学科特征和各个旅游研究主题的受关注程度:从主类来看,最受关注的是"目的地"领域,其次是"需求"和"营销"领域;从亚类来看,最受关注的是"市场细分"和"吸引物和节庆"领域,而"基础设施"、"交通(旅游目的地内部)"和"旅游客流"等领域受关注度最少。最后,本文试图寻求与旅游学学科树进行理论对话,重新检验了近10年国际旅游研究在国内分类框架的学科特征与演变趋势。展开更多
