“A difference-in-differences study of 276 Chinese cities over 1988-2010 associates the establishment of a state-level special economic zone with an increase in the level of GDP of about 20%, mainly through capital accumulation, but not with a permanently faster growth path.”

Context. The published abstract reports the 20% level effect, the 1988-2010 panel and the physical-capital channel; the sample size and the absence of a growth-rate effect are stated in the working-paper abstract.
