BEIJING -- The slowdown of China's once-sizzling economy has fueled anxiety over its impact on the rest of the world. Yet when Beijing reported Tuesday that its economy grew last year at the slowest pace in a quarter-century, the reaction seemed to be mainly relief it wasn't worse.

Economists welcomed details in the report suggesting that the world's second-biggest economy is making some progress in a difficult and complex transition -- away from a reliance on manufacturing and investment in real estate and factories and toward dependence on services and consumer spending.

Stocks rose Tuesday in Asia and Europe. By midday, the Dow Jones industrial average was up modestly.

"Things are OK," said Fotios Raptis, senior economist at TD Economics. "There's not an outright collapse going on in China."

Beijing reported that economic growth fell in 2015 for a fifth straight year -- to 6.9 per cent , down from 7.3 per cent in 2014 and the slowest rate since 1990. For the October-December quarter, growth inched down to 6.8 per cent, the weakest quarterly expansion in six years.

The deceleration is at least partially deliberate as the ruling Communist Party aims to manage the economy's transition to a structure that will almost certainly deliver slower growth.

Tuesday's report contained signs of progress. Services businesses accounted for a record 50.5 per cent of China's economic activity last year, the first time its share has exceeded 50 per cent.

Charles Collyns, chief economist at the Institute of International Finance, sees considerable potential for more growth in China's service sector. In more developed economies, services account for perhaps 75 per cent of economic activity. China's services have been held back by regulations and policies that favour inefficient state-owned service companies in such businesses as telecommunications and finance.

Services grew 8.3 per cent last year, outpacing the traditional drivers of economic growth -- manufacturing and construction -- which together grew 6 per cent.

Overall growth was in line with private-sector forecasts and the ruling Communist Party's official target of about 7 per cent for the year.

"Official data do not point to a hard landing in the fourth quarter of 2015, but they provide little reason to stop worrying about China's drag on the global economy, either," said economist Bill Adams of PNC Financial Services Group in a report.

Investors were relieved that more pessimistic forecasts about fourth-quarter growth were wrong and expect Beijing to continue rolling out stimulus measures to prevent a hard landing.

Beijing has responded to ebbing growth by cutting interest rates six times since November 2014 and launching measures to help exporters and other industries. But economists note that China still relies on state-led construction spending and other investment.

Full-year 2015 growth was the lowest since sanctions imposed on Beijing after its crackdown on the Tiananmen Square pro-democracy movement caused growth to plummet to 3.8 per cent in 1990.

The October-December growth figure was the slowest quarterly expansion since the global financial crisis, when growth slumped to 6.1 per cent in the first quarter of 2009.

"The international situation remains complex," Wang Bao'an, commissioner of the National Bureau of Statistics, said at a news conference. "Restructuring and upgrading is in an uphill stage. Comprehensively deepening reform is a daunting task."

Growth in investment in factories, housing and other fixed assets, a key economic driver, weakened to 12 per cent in 2015, down 2.9 percentage points from the previous year. Retail sales growth cooled to 10.6 per cent from 2014's 12 per cent.

December exports shrank 1.4 per cent from a year earlier, well below the ruling party's target of 6 per cent trade growth. For the full year, exports were down 7.6 per cent, a blow to industries that employ millions of Chinese workers.

Forecasters see indications that retail sales and other activity accelerated toward the end of 2015, suggesting that Beijing's efforts to put a floor under the downturn are gaining traction.

"The growth picture remains two-sided. The real estate construction slump and weak exports continued to weigh on activity," said Louis Kuijs of Oxford Economics in a report.

"Meanwhile, though, consumption continued to expand robustly, supported by solid wage growth," said Kuijs. "The robust growth in the consumption and services nexus is key for policymakers. They need it to avoid labour market stress."

Global financial markets were rattled by a plunge in Chinese stock prices in June. Chinese stock markets have little to do with the rest of its state-dominated economy, but investors abroad took the decline as a sign the economy as weaker than thought.

A growing number of private-sector analysts question the reliability of China's data, suggesting economic growth is much weaker than reported.

Julian Evans-Pritchard of Capital Economics said other measures of activity suggested economic growth in the latest quarter was 4.5 per cent, though that still would be among the world's strongest.

Spending on online commerce grew by 33.3 per cent over 2014, an encouraging sign for official efforts to nurture a consumer economy. Wang said the share of total economic activity accounted for by consumption rose to 56.4 per cent. That was up 5 percentage points from 2014.

Forecasters expect economic growth to decline further this year, with the International Monetary Fund targeting a 6.3 per cent expansion. Tuesday's "numbers are somewhat reassuring to markets, suggesting that some of their worst fears are not materializing," Collyns said.

Tuesday figures "fit the expectation of China watchers: The Chinese economy is slowing down, but only gradually," said David Dollar, senior fellow at the Brookings Institution and former China hand at the U.S. Treasury Department and the World Bank.
