This paper not only discusses the conditions of the spatial economic equilibrium, including production, consumption, resources allocation in space and regional disparities, but also makes some systemic economic models to allocate resources optionally in space and to set prices of merchandises and resources theoretically. According to the principle of multi-hierarchy con-trol of large-scale systemic theory, our economic society is divided into five parts: 1) consump- tion system, 2) production system, 3) system of resources allocation, 4) triffic system, and 5) coordination layer. These models expound profoundly the relations among production, con- sumption, resources allocation in space and regional disparities, which can also be regarded as a model of location theory.
