The output sub-index, one of the five component indicators of PMI, climbed to 55.7 in March from 53.8 the month before, the National Bureau of Statistics (NBS) said in a statement on Friday. For industries such as electronics, textiles and nonferrous metals, the figure rose above 60.

The rising output sub-index suggests that domestic industrial production has rebounded from February, when economic activity was affected by China's seven-day Lunar New Year holiday, according to the NBS.

"The rebound eases concern about a slowdown risk for the world's fastest-growing major economy," said Lu Yanjin, a senior analyst from Industrial Securities Co Ltd. Year-on-year economic growth in the first quarter could reach 9.5 percent, and is likely to maintain a rapid pace in the first half of the year.

The input price component of the PMI, which gauges major purchasing prices for producers and acts as an indicator of inflationary pressure, moderated to 68.3 from February's 70.1. Given the moderation of the sub-index, inflationary pressures have eased slightly, said Nomura Securities Co. China's consumer inflation rose to 4.9 percent in February, unchanged from January, but up from 4.6 percent in December.

The government has taken "wise and active" steps to tackle inflation, said Alex Malley, chief executive officer of CPA Australia, on Thursday.

China has taken a number of steps to control inflation, including the imposition of price controls on general goods and an increase in price support for grain producers. These measures have been complemented by greater control of real estate prices, interest rate increases, rises in the reserve requirements for banks and greater flexibility for yuan appreciation.

Inflationary pressure may continue, as the escalation of unrest in North Africa could result in a further rise in the price of oil, said Maria Malas-Mroueh, an economist at London-based Fitch Ratings Inc.

However, Yi Gang, vice-governor of the People's Bank of China, said last week that he was confident inflation would be kept at about 4 percent, the government's target.

The March PMI figures also indicate that a "hard-landing" for the Chinese economy can be ruled out. The growth in urban fixed-asset investment will continue to bolster the economy in the first year of the 12th Five-year Plan (2011-2015), said Nomura.

China's "economic growth is only moderating rather than slowing too much," said Qu Hongbin, HSBC's chief economist in China. "More importantly, the rate at which prices are rising has also started to slow."

"These factors confirm our view that quantitative tightening is working. As long as Beijing keeps tightening for another three to four months, inflation should start to slow meaningfully in the second half of 2011," he said.
