To fund the stimulus, China lifted longtime rules that prohibited local governments from accruing debt or running deficits, the researchers find. Freed from these constraints, local governments transferred land to investment vehicles to use as backing for bank loans or bond issuances. The researchers estimate that about 75 percent of China’s stimulus spending came from transactions through these entities, whose debt is not reflected in official tallies of government accounts.
The local governments continued to invest with off-balance-sheet transactions long after the stimulus ended. Although they continued to make significant investments in infrastructure, they put more of the money toward commercial projects by favored private companies, according to the study. “The aggregate effect is that the overall efficiency in the allocation of capital worsened . . . which lowers the aggregate growth rate,” the researchers write. They illustrate the point with figures that show aggregate growth rates declining significantly after stimulus ended in 2010, even though investment rates rose.
