China's fiscal deficit could widen by as much as 50 percent in 2013 to 1.2 trillion yuan ($192.4 billion), according to a report on Thursday. But experts doubted the necessity of such a move, due to the potential risks it may present.

The higher level, seen as an important step in the country's fiscal policies for the year, would lift the fiscal deficit from 1.5 percent of GDP in 2012 to 2.2 percent in 2013, China Business News reported,[Hong Kong Company Registration Guide] citing sources close to the matter.

The universally accepted alert level for a government's fiscal deficit is 3 percent of GDP.

The report said the government will widen the deficit to 1.2 trillion yuan from a projected 800 billion yuan for 2012, and 270 billion yuan would come from its budget stabilization fund.

On a positive note, analysts said a higher fiscal deficit could pave the way for larger investment in infrastructure and more tax reduction measures.

Liu Yuhui, chief economist with Huatai Securities Co Ltd, said the move suggested authorities were trying to promote an economic restructuring through a short-term fiscal deficit, which he viewed as a sound, market-oriented move.

He added the additional fiscal expenditure could be used to eliminate overcapacity in some industries, reduce debt and improve labor allocation.

"In the short term, these expenditures are necessary, and will be beneficial for economic transformation, laying the foundation for more fiscal income and a lower deficit in the future," he said.

However, some experts doubted the wisdom of raising the deficit level, in light of declining government income and the determination to lessen the nation's dependence on fiscal stimulus [Businesses Registration]to kick-start the economy.

China began to adopt a proactive fiscal stance in 2009, and the actual fiscal deficit-to-GDP ratio rose from 2.02 percent in 2009, resulting in a 50 billion yuan surplus in 2011.

However, fiscal budgets continue to face increased pressure from slowing growth in government revenue and larger expenditure.

In the first 11 months of this year, government revenue rose 11.9 percent but spending was up 17.9 percent.

"The conflict between revenue and expenditure will continue for some time," Vice-Finance Minister Li Yong told a recent conference.

Jia Kang, head of the Ministry of Finance's Research Institute for Fiscal Science, said as the economy warms in the next year, China should edge away from aggressive fiscal policies.

He expected the country's absolute fiscal deficit level to decrease, and said the deficit-to-GDP rate will also be lowered.

That view was echoed by Liu Shangxi, deputy chief of the institute, who added that it is easy to lift the fiscal deficit, but hard to reduce it, so the government can't rely on raising debt to lessen expenditure pressures.

"The major problem is in the structure of fiscal expenditures, not the overall amount," he said.

Fan Jianping, deputy director of economic forecasts at the State Information Center, said that although markets regard a larger fiscal deficit as a likely signal of more economic stimulus, the marginal effect of such a measure is actually insignificant.[Hong Kong Company Formation & Registration]

"A more important indicator would be the amount of funds raised by local governments - but that's also restricted by the rising debt repayment pressure faced by local authorities," Fan said.
