We regard technical innovation networks as complex network organizations which are formed by the modular nodes,and the diploid characteristic of network point module make the contradiction between the integrity of cooperation innovation network and the independence of module point contradiction needs to coordinate,which has surmounted the traditional organization theory.Weick's loosely coupled theory has provided the new viewpoint to understand it.With the analysis on the characteristics of technical innovation network and its module nodes,we construct the N-M (Network- Modularity) matrix that reflected the loosely coupled theory from two dimensions,which are the network integrity and the module independence.Then we put forward that technology innovation networks is a loosely coupled system.Additional- ly,we discuss the relation between the loosely organizational structure,the intensity of weak coupling and the coupling process on technical innovation networks.
