Abstract：The division of urban economic regions is an important content of urban system planning, and also the important aspect of urban science building. This paper analyzed the existing methods for the division of urban economic regions. Considering weighted Voronoi diagram's geometric particularity, the rationality for dividing up space and the solvability by computer, the paper tried to apply it in urban system studying. The exact boundary of each city's absorbed region in theory is found and the conception of breaking arc was put forward by analyzing the breaking point theory deeply ,and expanding the theory with weighted Voronoi diagram. The paper put forward new methods for selecting regional central cities and dividing urban economic regions by means of two kinds of weighted Voronoi diagrams, and gave an analytic demonstration taking Henan province as an example.
