Economic output has increased by just 0.2% in the nine months to June.
Output increased by 1.7 percent from the previous month, but it was still lower than the average level in 1997.
Still, industrial output increased 14 percent last year, to $277 billion.
Output has increased to an 11-year high of 24.2 million barrels a day.
Output, again in real terms, has increased by 25 per cent.
By 1868, annual output had increased to about 10,000 barrels.
Much of the export growth came from agriculture, where output increased 5.3 percent.
The company said its foreign crude output increased 11 percent, to 1.19 million barrels a day.
The industry's output has increased nearly tenfold since that time.
Economic output could increase as much as 6 percent, it added.
