房价为什么不跌？这个问题涉及到许多复杂的因素，包括经济、社会和政治等方面。以下是对这个问题的解析以及英文翻译对照：

首先，房价的涨跌受到市场供求关系的影响。当市场需求高于供应时，房价通常会上涨。反之，当供应大于需求时，房价通常会下跌。然而，中国等一些国家的房价常常受到政策因素的影响，如购房限制、土地供应等，这些因素会干扰市场供求关系，从而导致房价不跌。英文翻译为：Firstly, the rise and fall of housing prices is influenced by market supply and demand. When market demand is higher than supply, housing prices usually rise. Conversely, when supply exceeds demand, housing prices usually fall. However, housing prices in some countries such as China are often influenced by policy factors such as purchase restrictions and land supply, which can interfere with market supply and demand, resulting in housing prices not falling.

其次，房地产市场具有金融属性，与金融体系紧密相连。当经济不景气时，银行等金融机构可能会降低对房地产市场的贷款额度，从而减少市场上的流动资金，导致房价无法下跌。此外，房地产市场还与政府财政收入密切相关。当政府财政收入不足时，可能会采取措施干预房地产市场，以增加财政收入，这也可能导致房价不跌。英文翻译为：Secondly, the real estate market has financial attributes and is closely connected to the financial system. When the economy is sluggish, financial institutions such as banks may reduce their credit lines for the real estate market, thereby reducing the amount of liquidity in the market and causing housing prices to be unable to fall. In addition, the real estate market is also closely related to government financial revenue. When government financial revenue is insufficient, it may take measures to intervene in the real estate market to increase financial revenue, which may also lead to housing prices not falling.

综上所述，房价为什么不跌受到市场供求关系、政策因素和金融属性等多方面因素的影响。这些因素共同作用，导致了房价的涨跌趋势复杂多变。英文翻译为：In summary, the reasons why housing prices do not fall are influenced by various factors including market supply and demand, policy factors, and financial attributes. These factors act together to make the trend of housing price changes complex and volatile.
