【摘要】This paper studies the size distribution of exporting and non-exporting ?rms in apanel of Chinese provinces. The power law exponents of exporting ?rms are signi?cantly lessthan those of non-exporting ?rms. The average power law exponents fell from 0.74 in 1998 to0.64 in 2007 for exporting ?rms, and from 1.03 in 1998 to 0.83 in 2007 for non-exporting ?rms.Further analysis showed that credit constraints have a signi?cant negative effect on the expo-nents of the size distribution of exporting ?rms, suggesting that smaller ?rms are more credit-constrained than larger ?rms.
