中经评论：住宅以套内面积交易或成趋势

Core Viewpoint - The article discusses the shift from using construction area to usable area for residential property transactions in China, highlighting the potential benefits and implications of this change. Group 1: Impact on Housing Prices - Transitioning to transactions based on usable area is unlikely to significantly affect housing prices, as total prices are primarily determined by market supply and demand, although unit prices may be slightly higher when calculated on usable area [2]. Group 2: Understanding Common Area - Common area, which includes shared spaces like elevators and hallways, is currently included in the total construction area, leading to buyers paying for both usable and common areas [3][5]. - The lack of transparency regarding common area calculations has been a major concern for buyers, often resulting in confusion and disputes over actual usable space [7]. Group 3: Benefits of Usable Area Transactions - Using usable area for transactions can enhance the standardization and transparency of housing transactions, addressing discrepancies in usable space among properties with the same construction area [4][6]. - This approach aligns with international practices, potentially improving construction standards in China [6]. Group 4: Market Dynamics - The shift to usable area transactions may become a competitive advantage in the housing market, especially as the market transitions from a seller's market to a buyer's market, where buyers have more options and are more discerning about property features [8].
