Abundant orders usually please business owners, but Liu Yuxiang's overflowing order book is instead a source of anxiety.

Liu's company, a small auto parts maker in Chongqing municipality, has been swamped with orders lately - more than it can fill. But Liu doesn't have the money to expand capacity so that his company can meet demand. "We'll be pushed out of the market soon if we can't fill the orders," he told CCTV.

Liu is not alone - at least not in Chongqing. About 80 percent of the municipality's small businesses have not had access to bank loans since the government tightened credit to prevent excess liquidity from pushing up prices, Sun Shenlin, chairman of the local industrial and commercial association, said.
