Does anyone know where I can find a descriptive grammar and a generative grammar of Mandarin, in English or French?
There are quite a lot of Chinese grammar books. I have got one here:
Modern Mandarin Chinese Grammar: A Practical Guide
by Claudia Ross and Jing-heng Sheng Ma
Sold in Amazon ranging from $30 to $100.
EDIT: Tens of various grammar books are listed in Chinese Grammar Wiki. The one above is included.
Chinese Grammar Wiki
There are a lot websites about Chinese grammar online, just google for it.
I have a copy of 外国人实用汉语语法, I would say it is a excellent book, but the one I have is of an old edition. Here is the revised edition:
外国人实用汉语语法(修订本)(中英文对照) A PRACTICAL CHINESE GRAMMAR FOR FOREIGNERS(Revised Edition) (In both English and Chinese)
The article below gives background and development of generative grammars of Chinese, including discussions of germinal research problems and an extensive bibliography containing references to contemporary (1995) generative grammars of Chinese.
