How to design and build suitable organizational structure is very important for developing learning organi2 zation. Firstly , the previous researches on this area have been reviewed and analyzed. Then , five functional charac2 teristics (namely information/ intelligence function , innovation function , learning/ training function , knowledge man2 agement function , and change/ crisis management function) and four form characteristics (namely team2based/ net2 worked , flat , market/ customer oriented , elastic/ reconfigurable ) have been put forward based on Integrated Process Model (6P-1B model) of learning organization. Some cases have been studied to analyze and explain each of the above nine organizational structure characteristics. Future research direction has been discussed finally.
