He Daan’s study on investment operation mechanism in industrial structure change is of momentously theoretical and practical significance and provides an important theoretical reference for China to make industry policy.However,any movement can not be separated from the time,movement law can only be revealed in consecutive time,and so are investment activity and industrial structure change.Therefore,this paper,based on the research of He Daan,on the one hand,combines the mechanism analysis in static status with the process of dynamic change of industrial structure by taking the "time" factor into consideration,which provides a theoretical support for feasibility of empirical analysis.On the other hand,we find that scattered-style investment is a kind of the abstraction and simplification of consecutive investment and has certain dynamic property.To some extent,thus,dynamic analysis provides theoretical support for the feasibility of static analysis.
