What this figure means

PPP re-prices pay for local living costs. Shanghai sets the benchmark price level; every other card's gross is derived from the shared gross benchmark and re-priced at Shanghai's prices, so every card's buying power is measured on the same price basis.

What this figure means

PPP re-prices pay for local living costs. Shanghai's average prices are 9% lower than Hong Kong's (indexed price level). Both cards start from the same nominal gross of HK$588,140.
