Group 1 - The core argument presented by Professor Yao Yang is that the speed of housing price adjustments is too slow, leading to hesitation among the public regarding home purchases. He believes the fundamental issue is not a lack of funds among ordinary citizens, but rather that housing prices have not fallen to acceptable levels [1][3][5] - The continuous rise in housing prices has diminished the enthusiasm of the public for home buying, resulting in a market activity level that is far below expectations. Despite various government policies aimed at controlling prices, the root problems remain unaddressed, leading to a persistent supply-demand imbalance [5][12][14] - The soaring housing prices have contributed to social inequality, making home ownership increasingly unattainable for middle and low-income families. This situation has forced many families to rent long-term or face homelessness, causing significant distress [9][10][12] Group 2 - Professor Yao Yang challenges traditional economic theories by suggesting that the fluctuations in housing prices are the primary factor influencing buyers' decisions, rather than just their economic conditions. He posits that a decline in prices could stimulate market activity by changing buyer expectations [18][21][23] - The profitability of real estate investments has diminished as housing prices have surged, leading many investors to withdraw from the market. This has created a situation where even those needing housing are overwhelmed by high prices, resulting in increased pressure on families [26][28][30] - Government measures to control the housing market, such as increasing down payment ratios and tightening loan conditions, have had limited effectiveness and have not fundamentally resolved the supply-demand issues. The market is transitioning from a phase of prosperity to one of deep adjustment, presenting future challenges [30][32][35]
