China's economy lost further momentum in October, with factory growth dipping and investment growth hitting a near 13-year low.

The figures reinforce expectations that Beijing will need to do more to fight slackening growth. 

They also cemented the view that China is on track to grow at its weakest pace in 24 years, but leaders remain reluctant to use full-blown policy easing, such as cutting interest rates. 

Fixed-asset investment, an important driver of growth, grew 15.9% in the first 10 months of the year from a year ago, the National Bureau of Statistics said. That was the weakest pace since December 2001. 

October factory output rose 7.7%, which was higher that August's 6.9% but below forecasts and the second weakest pace since the height of the global financial crisis. 

Retail sales growth eased to 11.5%, the slowest pace since early 2006.

The anti-corruption drive spearheaded by President Xi Jinping has hit sales of luxury goods and expensive dining and also cooled down a craze among local governments to launch new investment projects. 

"All three activity indicators weakened moderately, suggesting the downward trend in GDP growth has not been arrested yet. I would expect growth to be lower in the fourth quarter than in the third quarter," economists said. 

They pointed out that industrial production of 7.7% roughly corresponded to economic growth of 7.1%. 

Despite a raft of stimulus measures, China's growth slowed to 7.3% in the third quarter, the weakest since the global financial crisis. 

Economists polled by Reuters had forecast retail sales and industrial output to rise 11.6% and 8%, while fixed asset investment was seen up 15.9%. 

Other data this week showed inflation remained near a five-year low, highlighting sluggish domestic demand but leaving room for more policy support measures. 

Analysts believe more support may be needed to offset the drag from the cooling housing market, but are divided over whether Beijing will take more forceful action such as cutting interest rates unless there is a risk of a sharper slowdown. 

Growth in property investment, which affects about 40 other industries in China, cooled to 12.4% in the first 10 months of 2014 from a year earlier. 

New construction continued to fall, but a slump in property sales showing some signs of easing as banks quickened mortgage approvals and offered better rates to some buyers. 

Analysts doubted whether government moves in September to lower mortgage rates would stem the slide as a glut of unsold units hangs over the market. Many see the sector remaining weak well into 2015. 

The central bank, which pumped 769.5 billion yuan ($125 billion) worth of three-month loans into banks in September and October, has pledged to keep its policy stance accommodative but stressed it will not flood markets with cash. 

Chinese leaders have repeatedly flagged they tolerate slower economic growth as long as the job market remains strong.
