Just to add my 50 cents (-_-) about GREYing
Development level is very uneven across China with most developed and advanced areas being
- Bohai-Sea Rim (centers - Beijing Tianjin, Dalian, Qingdao...)
- Yangtze River Delta (Shanghai, Suzhou, Nanjing)
- Pearl River Delta (Hong Kong, Shenzhen, Guangzhou)
Still enormous untapped potential in inland areas, for industrialization, for consumption...
Nowadays there's a more and more visible trend of migration of industries and investment and know-how from the the above mentioned powerhouses to less developed hinterlands (Central China, and then the West).
For example, most evidently Foxconn in Shenzhen, who was in deep trouble of labor unrest recently, is now busy setting up new bases in Zhengzhou (Central China), and Chongqing (West) where cheap labor is abundant. The government encourages such a go-west trend as it absorbs a large number of workforce (migrant workers) locally who may stay instead of going to the Coastal for employment. Certainly improved INFRASTRUCTURES is an anabler for the move.
Chengdu (West) in fact has made a headway in 'copying' Banglore model of turning itself into a centre of back-office outsourcing for multinationals (at this stage domestically). Chongqing (West) and Wuhan (Central) are boasting of becoming China's 'Chicago'.

Conclusion: Still a long way to go before real 'greying' takes place and an end of 'demographic dividend'.
