BERLIN, Aug. 23 (Xinhua) -- German economy expanded by 0.7 percent in the second quarter of 2013 compared with the previous quarter, German Federal Statistical Office said on Friday, confirming its preliminary estimate on August 14th.
It was the strongest quarter-on-quarter growth since the first three months of 2012, when gross domestic product in the Europe's largest economy rose by 0.7 percent.
According to the Wiesbaden-based Statistical Office, positive contributions to GDP growth were made mainly by domestic demand, especially by investment.
Investment in construction increased significantly by 2.6 percent on the first quarter of 2013. This was probably due to whether-related catch-up effects following a unusually long and cold winter in Germany.
In the sector of machinery and equipment, investment also advanced by 0.9 percent.
Households spending increased 0.5 percent than in the first three months through March. Government spending was up by 0.6 percent during the same period.
In addition, net trade supported the GDP growth by 0.2 percentage points. 2.2 percent more were exported than in the previous quarter. The imports also rose by 2.0 percent.
"The development of the German economy is gaining momentum, following a weak start into the year," said the Statistical Office. German economy stagnated in the first quarter of 2013, following a contraction of 0.5 percent in the last three months of 2012.
Earlier on Friday, the Statistical Office reported that German general government achieved surplus of 8.5 billion euros in the first half of 2013, with a revenue of 604.5 billion euros and expenditure of 596 billion euros.
The most important source of government income was taxes, which accounted for half of the total revenue and increased by 5.6 percent in the first half of the year. Trade tax rose by 8.4 percent and corporation tax by 8.1 percent.
Strong economy in Germany boosted confidence that the euro zone would be brought out of the on-going recession soon. According to a provisional estimate of Eurostat, the statistical office of the European Union, GDP of the euro zone grew by 0.3 percent in the second quarter, thanks to the the expansion of 0.7 percent in Germany and 0.5 percent in France.
