Regional economic relations and central city function diffusion has been an important issue of eco -nomic geography and regional economic research .Based on the analysis of the function of Hangzhou City , the func-tion of the diffusion type is analyzed and the economic connection intensity model is used to explore the spatial difference of the economic linkage intensity and the function of the central city .Research shows that different from the economic strength of Hangzhou , it will present different types of urban functions in the close level of urban spa-tial distribution;Economic relation intensity weak areas , great demand for education , health care, etc.Therefore, compact city layer should strengthen links with the center of the city of Hangzhou , more specifically , according to the size of the intensity of the economic contact , formulate scientific policy and docking platform , selected docking function diffusion type .%区域经济联系和城市圈中心城市功能扩散一直是经济地理学和区域经济研究的重要内容.通过对杭州都市圈在其紧密层城市的功能扩散类型分析,运用经济联系强度模型,探讨了经济联系强度与中心城市功能扩散的空间差异.研究表明:与杭州经济联系强度不同,会在紧密层城市空间布局上呈现不同城市功能类型;经济联系强度偏弱的地区,反而对教育、医疗、科技等高端功能要素需求比较大.因此,紧密层城市在加强与杭州中心城市联系的同时,按照经济联系强度大小,科学制订对接政策和平台,有选择地对接杭州中心城市功能扩散类型.
