On the background of global integration, urban agglomeration is becoming a main direction of global spatial reconstruction and the basic unit of competition between regions and countries. Based on systematical summary of structural research on domestic and aboard urban agglomeration, this article analyzed the characteristics of four categories of structural elements (including node, channel, flow and matrix) from the perspective of spatial elements system of agglomeration. The information about the spatial elements in central Zhejiang urban agglomeration was acquired through wide-spread interviews and questionnaires of government departments and typical corporates. The article also quantitatively analyzed the characteristics of spatial structure in central Zhejiang urban agglomeration, and explored the empirical methods about the researches on urban agglomeration. The result showed that the central Zhejiang urban agglomeration’s structure appears to be networking and multi-central, which includes Yiwu and Jinhua. The core area presents a strong networking showing a certain degree of homogeneity and continuity in economic, demographic and geographic landscape. Such researches would provide foundation for further quantitative assessment and strategic decision.
