Private Rental Listings in Beijing, 2015 and 2018

The dataset includes rental listings from Lianjia (http://bj.lianjia.com) and Woaiwojia (https://bj.5i5j.com) in 2015 and 2018. I employed a web-scraping software program to collect rental listings every Sunday from January to March in 2015 and 2018. The information collected includes the unit’s geographical location, floor area (in square meters), and monthly rent. I then removed items that were duplicates from the original raw collections, items that contained invalid or incomplete information, and items that were not about residential units but storage or commercial spaces.

本数据集包含2015年与2018年来自链家（Lianjia，http://bj.lianjia.com）与我爱我家（Woaiwojia，https://bj.5i5j.com）的租房房源信息。笔者于2015年与2018年的1月至3月期间，每周日通过网络爬虫软件采集上述平台的租房房源数据。所采集的信息涵盖房源的地理位置、建筑面积（单位：平方米）与月租金。随后笔者对原始采集的数据集进行预处理，剔除了重复条目、包含无效或不完整信息的条目，以及非住宅类的储物或商业空间相关房源。
