Capitalness Index of the UN Member States Capital Cities

The database presents the information on UN member states' capital cities including geographic coordinates (latitude and longitude) as well as the capitalness index calculated by the authors. The database lays the foundation for comparative capital studies, especially studying their place in political and territorial structure of the state and using spatial statictics methodology. The dataset can be used to fasilitate accumulating, visualizing and analysing statistical materials in capital studies. Another important potential use of the base is creating a special neighbourhood matrix based on the closeness of capitals, not state centroids.

本数据库收录了联合国会员国首都的相关信息，包含地理坐标（纬度与经度），以及作者自行计算的首都地位指数（capitalness index）。本数据库为首都比较研究奠定了学术基础，尤其适用于探究首都在国家政治与领土结构中的定位，以及运用空间统计（spatial statistics）方法开展相关研究。本数据集可助力首都研究领域内统计资料的归集、可视化与分析工作。该数据库另一重要潜在应用场景，是基于首都而非国家几何中心的邻近性构建专属邻接矩阵（neighbourhood matrix）。
