Drivers of structural similarity

The dataset contains a measure of structural similarity/convergence (pairwise Krugman specialization index) along with 54 potential determinants of structural similarity.本数据集包含结构相似性/趋同的衡量指标——两两克鲁格曼专业化指数（pairwise Krugman specialization index），同时收录了54个影响结构相似性的潜在决定因素。
