Abstract: According to the theory of areal economy system, the state of an areal economy unit can be expressed with the features of time series of the economic development and spatial structure. The existing state of an areal economy unit is enslaved to the space-time relationship. The determinative area in a given stage of economic development is bound to have its periodical feature of economic development which is relative to the feature of its spatial structure. Conversely, the feature of spatial structure of the area is bound to reflect the feature of stage of the areal economy development. On the basis of the above, this paper makes a preliminary diagnosis of the features of time series of industrial system in Fujian and spatial structure from the space-time relationship. In the period of economic development, Fujian is in a period of transition from the exploitation of resources to processing industries. In the spatial respect, the economic development of Fujian takes on the feature of pole-axis spatial system that is growing. The coupling of space and time indicates that the economic development of Fujian has been in the mid-term of industrialization. At last, the paper puts forward countermeasures and proposals to push the course of industrialization forward and realize the stage leap forword of industrial economic system of Fujian.
