Tibet and Chongqing came at the top of 27 Chinese provinces and municipalities that had released interim GDP growth figures as of Wednesday. Both reached a 10.6% growth, up 3.9 percent points from the national average in the same period though slightly down by 0.1 ppt from that of the first quarter.

It also marks a 23-year streak of double digit growth of the Tibet Autonomous Region. Chongqing, a southwest municipality directly under the central government’s supervision along with Beijing, Shanghai and Tianjin, has championed the first place in GDP growth for 10 consecutive quarters since 2014’s first quarter. Though Shanxi, Heilongjiang and Liaoning have not announced their figures yet, they are expected to record the poorest performances by province considering their industrial structure and previous data.

Generally, the middle-upper reaches of the Yangtze River and other hinterland provinces have defied the economic headwinds that hold back growth in the more developed eastern coastal provinces.

The upbeat trends in these regions are grounded in four aspects, namely 1) relative independence of export-oriented business compared to coastal cities, 2) better industrial structure and abundance in resources and labor by contrast with energy-dependent, traditional industries-ridden northern regions, 3) more enterprises having been attracted to these regions thanks to improved transportation conditions, and 4) strong investment in infrastructure.
