China's Greater Bay Area (GBA): here's how the housing markets in the select cities in the GBA perform vs other major cities across China, when we look at the last 12 months, with the consistent data to May 2021. 

The top chart shows a strong relative house price growth over the period (Y axis), while Shenzhen figures now reflect the waves of policy tightening and price controls. The cities enjoy strong sales volume growth (X-axis, in Gross Floor Area), with Dongguan, Guangzhou, and Zhongshan strong on both metrics.

The second chart depicts land acquisitions by 20 major national developers (some based in the GBA) across all cities (X-axis: total planned GFA, Y-axis: average land price paid, bubble size: land transaction value in RMB) highlighting the same cities in the GBA. Shenzhen stands out on price, Foshan on scale, and Guangzhou and Dongguan are relatively high on both.
