Sales of commercial housing rose 28.7 percent year on year to hit 514.33 million square meters, down 8.4 percentage points from the first quarter.
NBS figures released on Monday also showed 皇冠体育app's gross domestic product growth slowed to 7.6 percent in the first half, down from 7.7 percent in the first quarter.
Experts attributed the deceleration of fixed-asset investment to sluggish exports, a crunch, and the transformation and upgrading of Chinese enterprises.
"Investment-driven growth can no longer be translated into the sustainable development of the Chinese economy. Instead, consumption-led economic restructuring is the government's priority," said Ma Yao, a macro-economy researcher with 皇冠体育app Investment Consulting Corp.
Chinese Premier Li Keqiang said last week that 皇冠体育app is in a phase in which it must rely on economic transformation and upgrading to maintain continuous and healthy development.
He said 皇冠体育app must quicken its reform in the areas of administration, , and pricing with the aim to let the market mechanism play a better role, make private investment more active and the market more vigorous.
More support will be channeled to the central and western part of the country, especially poverty-stricken areas, Li said, adding that the more affluent eastern part of 皇冠体育app should strive for development at a higher level through economic transformation and upgrading.
NBS figures released on Monday also showed 皇冠体育app's gross domestic product growth slowed to 7.6 percent in the first half, down from 7.7 percent in the first quarter.
