贵阳市各区县二手房成交核心楼盘监测数据集

1、数据采集：从不动产登记系统中依法合规采集贵阳市各区县二手房成交数据（以2025年4月-2025年9月的数据为例）。原始数据包括各楼盘项目的成交套数、成交面积、所在行政区划、项目名称等字段。采集周期为月度，确保数据时效性与代表性。
2、数据处理：1）以“项目名称”为关键标识，对多源数据进行清洗与归一化，统一命名规则；2）按行政区划（区/县）进行分组统计，计算每个项目的累计成交套数与累计成交面积；3）基于全市总成交面积，计算各项目在当期市场的市场占比（%）；4）设定筛选阈值：仅保留“成交面积排名前20”的活跃项目，形成“核心楼盘清单”；5）生成结构化、标准化的“核心楼盘监测数据集”，包含“成交面积排名”“项目名称”“成交套数”“成交面积”“市场占比”等关键指标。
3、数据应用：输出高质量的核心楼盘榜单，可用于发布《贵阳市二手房市场月报》、支持城市更新项目选址、辅助开发商判断新盘布局、指导购房者识别市场热点区域、为金融信贷机构提供抵押物价值评估依据及服务政府开展房地产市场运行监测与预警。

1. Data Collection: Legally and compliantly collect second-hand housing transaction data of each district and county in Guiyang from the real estate registration system (taking the data from April 2025 to September 2025 as an example). The original data covers fields including the number of transaction units, transaction area, administrative division where the project is located, and project name of each real estate project. The collection is conducted on a monthly basis to ensure data timeliness and representativeness.
2. Data Processing: 1) Clean and normalize multi-source data with "project name" as the key identifier, and unify the naming specifications; 2) Group and conduct statistics according to administrative divisions (districts/counties), and calculate the cumulative transaction units and cumulative transaction area of each project; 3) Calculate the market share (%) of each project in the current market based on the total transaction area of the entire city; 4) Set a screening threshold: only retain the active projects ranked top 20 by transaction area to form the "Core Real Estate List"; 5) Generate a structured and standardized "Core Real Estate Monitoring Dataset", which includes key indicators such as "transaction area ranking", "project name", "transaction units", "transaction area" and "market share".
3. Data Application: Output high-quality core real estate rankings, which can be used to release the *Guiyang Second-hand Housing Market Monthly Report*, support site selection for urban renewal projects, assist developers in judging new housing layout, guide homebuyers to identify market hotspots, provide a basis for financial credit institutions to conduct collateral value evaluation, and serve the government in carrying out real estate market operation monitoring and early warning.
