Historical GDP estimates for China by Broadberry, Guan, and Li are problematic because of an implausible series for government expenditure. Revised estimates reduce GDP per capita, mainly during the Ming, by up to a third. Two peaks in income now stand out: the Song efflorescence and the years around 1700. If the latter peak is real, comparisons of the Yangzi delta with leading European countries show a Great Crossing in the middle ages, a Great Convergence in the seventeenth century, and a Great Divergence in the eighteenth. Otherwise, the Great Divergence may date from the sixteenth century. Covers 0980 – 1840.
