Maintaining Hong Kong's overall competitiveness is an important mission for the new government of Hong Kong. In the first half of this year, Hong Kong sold $ 17 billion in new properties with an average price of $ 1.8 million. At present, Hong Kong has the world's most unaffordable housing compared to income, the median house price is equivalent to 18 years of total household income; this is assuming that Hong Kong people do not need to pay taxes with no other living expenses. Hong Kong's real estate prices have risen to record highs, including a wide range of factors including the influx of mainland funds, which will not only exceed the affordability of the general public in Hong Kong, but will also raise the cost of living and business costs in Hong Kong. This trend, if sustained, will seriously undermine Hong Kong's overall competitiveness.
