【明報專訊】THE auction of a site in Tung Chung, which the auctioneer has described as "unusual", shows that Hong Kong's property market is complicated, that many factors may cause changes in it and, one may say, that the government's measures to regulate it have begun to produce results. However, if the government's policy remains as it is, new flats will still be in short supply in the next three to five years. The government must not think it has succeeded at one go just because of the auction. It should take the long view. It should try in earnest to rationalise the supply and demand of flats and building sites and ensure that sales of uncompleted flats are fair and reasonable so that the property market will develop healthily.
