Is that a news?
I already have read that in wiki article, long before certification of Blomberg.
The point is China's services economy is dominating Chinese GDP.
Hence, western articles that focus on strictly counting train cars for rail shipment is misguided.
Also, western media reports are too narrowly focused on China's electricity consumption for manufacturing.
Since China's economy is now being dominated by services, the old ways of measuring China's economy is outdated.
The new metrics must measure service companies' (such as Alibaba, Baidu, and Didi Chuxing) contribution to the Chinese economy.
