China's regional economies generally posted slower gross domestic product growth in the second quarter, in line with the slowdown in the national economy.

Analysts said hinterland regions should particularly boost their competitiveness as fixed-asset investment, a traditional engine for these regions, is unlikely to accelerate significantly in the second half of this year.

Of the 14 municipalities and provinces across China that have published their GDP figures in the first half of the year, 10 provincial regions' growth rates dropped compared with the first quarter. Three regions maintained the same growth rate, while one rose.
