"房子都盖到'供大于求'了，怎么还在不停地建新盘？" 大家的感觉并不是凭空来的——很多小区到了晚上，亮灯没几家； 三四线城市的库存要几年甚至更久才能卖完；中介嘴里永远是"房源太多，客户太少"。 那问题就来了： 既然明显过剩，开发商为啥还要不停拿地、盖楼，往里砸钱？ 今天我们就把这件事从里到外讲清楚。 一、房子到底过剩到什么程度？ 先看几组真实数据，不是瞎编的： 空置率：不同机构说法略有出入，但很多研究都提到，全国城镇住房空置率在20%左右，有的三四线城 市甚至超过30%，个别县城春节空置率峰值能到40%以上。 按国际通行说法，空置率超过20%就属于"严重积压区"。 如果按简单逻辑，"供大于求就该停工"，早就该全面刹车了。 但现实里，我们看到的是： 很多高库存城市，土地还在卖，只是节奏慢了点；一些房企资金链已经很紧，也还是在积极拿地；城市 里一边空置房多，一边新工地塔吊还在转。 这背后其实不是傻，而是一套复杂的现实逻辑。 去化周期： 一些城市的新房库存去化周期（按当前卖房速度卖完要多久）超过22个月，创下十多年新高。 三四线当中，半数城市库存消化周期在30个月以上，有的地方甚至要五六年。 另外有研究估算，从广义 ...
