The author has provided the first step in the field of the economic history of the Yüan, which is one of the most complex in all of Chinese history. Herbert Franz Schurmann has made a thorough analysis, section by section, of the economic part of the Dynastic History. He has used the parts of the Chinese source entitled “land tenure,” “agriculture and sericulture,” “land and head taxes,” “household taxes,” etc. This work will be of great value to historians and economists.
