AI 中文摘要
公寓交易记录对研究住房市场、家庭金融、区域经济和宏观金融传导很有用，但交易数据通常与上下文社会经济指标分开分布。我们展示了KRAFT，这是一个涵盖2015年1月至2024年12月韩国公寓销售的全国性交易级数据集。该数据集包含17个广域市地区的5320379笔公寓销售交易，包括交易时间、行政位置、专属居住面积、报告的交易价格、楼层和建筑年份。KRAFT还提供了涵盖宏观金融状况、人口结构、教育基础设施、私立教育支出、房价指数、消费者信心和经济政策不确定性的辅助指标。发布的文件按年度交易文件和单独的辅助数据表组织，以保留每个来源的原始时间和空间分辨率。KRAFT支持对公寓价格建模、区域住房市场比较、住房需求分析以及住房交易与社会经济背景之间联系的可重复研究。
英文摘要
Apartment transaction records are useful for studying housing markets, household finance, regional economics, and macro-financial transmission, but transaction data are often distributed separately from contextual socioeconomic indicators. We present KRAFT, a nationwide transaction-level dataset of South Korean apartment sales from January 2015 to December 2024. The dataset contains 5,320,379 apartment sale transactions across all 17 Sido regions and includes transaction timing, administrative location, exclusive residential area, reported transaction price, floor level, and construction year. KRAFT also provides auxiliary indicators covering macro-financial conditions, demographic structure, education infrastructure, private education expenditure, housing price indices, consumer sentiment, and economic policy uncertainty. The released files are organized as year-specific transaction files and separate auxiliary data tables to preserve the original temporal and spatial resolution of each source. KRAFT supports reproducible research on apartment price modeling, regional housing-market comparison, housing-demand analysis, and links between housing transactions and socioeconomic context.
