DONGGUAN, China (Reuters) - Millions of migrant workers streaming back to China's industrial heartland after the long lunar New Year break are facing an uncertain future, as smaller factories in particular struggle to cope with anemic orders and rising inventories.

In the Pearl River Delta, the "world's workshop" in southern Guangdong province that accounts for around a quarter of China's exports, workers and business owners say production lines have been slower than usual to restart after the annual two-week holiday.

At the Xicheng industrial park in Hengli, several factories lay gutted with broken machines strewn outside, while plots of land earmarked for industrial use were being used by villagers to grow vegetables, a sign of the weak demand for Chinese goods that is forcing business closures and putting pressure on wages.

"Finding a factory with a good salary, that's what we want," said Luo Xianrong, an 18-year-old laid off by a factory in January, who was one of scores of migrants knocking on factory gates in the hunt for new work.

"We have to be careful. Many factories aren't providing food and accommodation, and they're delaying wage payments," she said, as her four friends nodded in unison. "I don't want to be cheated."

While global policymakers gathered in Shanghai for a G20 meeting at the weekend declared that "growth in key emerging markets remains strong", the slowdown in China - the motor of the world economy for the past decade - has unnerved investors and contributed to market turbulence at the start of 2016.

The plight of Luo and her friends underlines the dilemma for China's leaders - they want to shift the economy away from the low-end manufacturing that fueled its rise, but they also need jobs for the consumers they hope will support its next phase.

Labor activists also point to the risk of unrest, as industries consolidate and workers find their benefits squeezed.

MANUFACTURING CONTRACTION

China's manufacturing sector likely contracted for a seventh straight month in February,, with the latest numbers due on Tuesday. The official purchasing managers' index is expected to show the sector shrinking at its fastest pace since August 2012.

Exports from Guangdong province - which has a bigger economy than Indonesia - are predicted to grow just 1 percent this year, according to a January government work report.

Analysts say many of the smaller factories hit hardest by the slowdown catered more for domestic demand than the export market, another signal that the Chinese consumer is not picking up the slack as is needed to rebalance the economy.
