目前预售的定金占到了开发商资金来源的三分之一，如果这部分资金来源被延，对开发商而言是致命的事情。这个研究方案最早由央行提出，但目前整个金融制度创新并不够，如果预售制有变化，会对供应产生比较大的影响，对目前市场形成很大的冲击。

At present the deposit to open to booking accounted for a third of the capital source developers，If the fund source was washed out，For developers are deadly things。The study by the central bank puts forward the scheme，But now the whole financial system innovation and not enough，If open to booking system have change，To produce larger will supply the influence，At present the market form to a big impact。

　　房地产市场从2005年开始出现供小于求，也就是竣工面积小于销售面积，为何要限购，其实就是指供应不够才限购，目前尽管库存比较高，但如果需求释放，库存会很快被去化，所以，增加供应才是维持市场稳定的主要因素。

The real estate market from 2005 began to appear for less than request，Also is an area smaller than the completion of sales，Why 限购，In fact is not enough to supply to 限购，At present although inventory is quite high，But if demand release，Inventory will soon be to change，so，Increase supply is the main factors of maintaining market stability。

　　如果未来预售制会被取消，那么有两个前提：一是有了金融创新的东西，比如未来资金来自于基金等，基金实力比较强，能够容忍期房变成现房的资金压力，由此替代预收款对于房企的作用；另外，现房当然比期房可靠度更大，但取消预售，要等到有很多的供应，购房者有多重选择，市场相对更成熟之时。

If the future to open to booking system will be cancelled，So there are two premise：The first is financial innovation of things，Such as the future will come from funds，Fund strength is stronger，Can tolerate period room into a house financial pressure，This alternative deposit for room the role of enterprises；In addition，A house of course more than period room reliability，But cancel to open to booking，Wait to have a lot of supplies，The person that buy a house have multiple choice，The market is relatively more mature。
