Regional Real Estate Price Index for Germany - SUF, 2008-05/2024

Based on the RWI-GEO-RED data that base on the data provided by ImmobilienScout24 hedonic housing price indices are estimated. The indices are on the grid level, LMR, district/county and municipality level. We conduct a hedonic price regression that covers characteristics of the object as well as regional fixed effects. The hedonic regression is estimated separately for houses for sale as well as apartments for rent and for sale. We also offer a combined index which combines the individual housing types into one index. There are three different specifications: First, the overall time development from 01/2008 to 05/2024 on grid level given yearly and quaterly; Second, cross-regional differences for each year separately and time development within one region from 01/2018 to 05/2024 (municipality, district, LMR, and grid level); third, the time-region fixed effect between 2008 and 2024, which is used to determine the price changes for all three region types to the base year of 2008.

本数据集依托ImmobilienScout24提供的RWI-GEO-RED数据，估算得到特征价格住房价格指数。该指数覆盖栅格级、劳动力市场区域（LMR）、区县及市级行政单元层面。我们构建了涵盖住房标的特征与区域固定效应的特征价格回归模型，并分别针对待售独栋住宅、出租公寓与待售公寓开展独立回归估算。本数据集同时提供整合型价格指数，将上述各类住房品类整合为单一综合指数。
本数据集包含三种不同的指数设定形式：其一为栅格级层面的整体时间趋势指数，覆盖2008年1月至2024年5月，按年度与季度发布；其二为分维度对比指数，包含分年度跨区域差异指数，以及2018年1月至2024年5月期间单一区域内的时间趋势指数，覆盖市级、区县、劳动力市场区域（LMR）及栅格级行政单元；其三为2008年至2024年的时间-区域固定效应指数，用于测算三类区域行政单元相较于2008年基准年的价格变动幅度。
