What percentage of Hong Kong's GDP is accounted for by the real estate industry?

The real estate industry in Hong Kong plays a significant and influential role in the economy, accounting for a substantial portion of the city's Gross Domestic Product (GDP). While estimates may vary, it is widely recognized that the sector contributes more than 20% to the total GDP. This substantial percentage reflects the importance of real estate development, property transactions, and related services within Hong Kong's economic landscape. Given the city's limited land supply and high demand for both residential and commercial properties, the real estate sector's contribution is crucial to the overall health and growth of the economy.

In contrast, the other options suggest lower percentages which do not accurately capture the reality of the industry’s economic impact. The choice stating more than 20% aligns with current data and reflects the actual situation of the real estate market in Hong Kong.
