According to foreign reporters based in mainland China, over the past six years the mainland government has spent RMB400 billion (about NT $ 2 trillion) on Expo 2010 and accompanying urban infrastructure. Although the mainland authorities deny this figure, in light of the extensive construction endlessly taking place in Shanghai in recent years, it can't be too far off.
據大陸的駐外媒體估計，中國官方這 6 年來至少投入了 4,000 億人民幣（約新台幣 2 兆元）進行世博建設和城市配套工程，這個數字雖遭官方否認，但由上海這幾年讓人目不暇給的整體改造觀之，應是「雖不中亦不遠矣」。
