Group 1 - The core argument is that attributing the decline of the Chinese real estate market solely to the decreasing birth rate is methodologically flawed [2][4] - The real issue lies in the high ratio of housing prices to residents' income, rather than a simple population decrease [6][8] - There remains a significant potential demand for housing in China, with millions of people yet to move to urban areas, indicating that the problem is not about a lack of people [6][8] Group 2 - The continuous decline in the real estate market over the past four years is a critical concern, and while population factors play a role, they should not overshadow the fundamental economic realities [4][6] - The argument that more people would automatically lead to a thriving real estate market is oversimplified; economic conditions and income levels are more decisive [8] - The potential housing demand is substantial, with estimates suggesting a need for hundreds of billions of square meters of housing based on urban population growth [6]
