二手结构 | 8月刚需发力，京沪深小面积低总价成交占比持增

Core Viewpoint - The second-hand housing market in major cities like Beijing, Shanghai, Shenzhen, and Hangzhou is expected to see a surge in transactions as September coincides with the end of the quarter, despite a general decline in transaction volume since Q3 2025. The market remains in a high-level oscillation phase, with low-priced, essential demand driving sales, while high-end luxury transactions stabilize [1][15]. Transaction Volume and Trends - In August 2025, the cumulative year-on-year increase in second-hand housing transactions in 30 key cities was 9%, significantly outperforming new housing transactions, which showed a decline [2][15]. - The proportion of transactions under 2 million yuan in Beijing, Shanghai, Shenzhen, and Hangzhou has increased year-on-year, indicating that essential buyers remain the primary force in the market [3][15]. Price Segmentation - The share of transactions in the low total price segment (under 2 million yuan) has increased, with Shanghai seeing 43.78% of transactions in this category, up 6.45% year-on-year. In contrast, the mid-range segment (3-6 million yuan) has seen a decline in transaction share, reflecting increased buyer hesitation [3][4][15]. - High-end demand remains stable, with luxury properties (over 50 million yuan) in Beijing, Shanghai, and Shenzhen maintaining their market share, while Hangzhou's mid-range (8-30 million yuan) transactions have increased [4][15]. Area and Size Distribution - The majority of transactions in Beijing, Shanghai, and Shenzhen are concentrated in small-sized properties (under 90 square meters), which account for over 60% of total transactions. This trend is driven by a strategy of "price for volume" as sellers aim to move inventory quickly [8][15]. - In Hangzhou, there has been a notable increase in transactions for medium to large-sized properties (100-180 square meters), catering to buyers looking for more functional living spaces [8][15]. Regional Concentration - The transaction concentration in key districts of Beijing, Shanghai, Shenzhen, and Hangzhou has increased, with notable growth in areas like Beijing's Chaoyang and Shanghai's Yangpu districts. However, the overall concentration in major districts is decreasing, indicating a shift towards suburban and core urban areas [12][15]. Market Outlook - The second-hand housing market is expected to continue its high-level oscillation, with price-driven demand from essential buyers. The market's transition to a buyer's market suggests that buyers will prioritize location, amenities, and price when making purchasing decisions, potentially extending the transaction cycle for less desirable properties [15].
