摘　　要：以淮海经济区为研究对象,采用空间偏离-份额模型研究2005-2019年淮海经济区服务业的演变趋势与特征.结果表明:研究期内,该区服务业整体实际增速高于份额增速,服务业发展水平高于平均水平的区域范围快速扩大,传统服务业发展普遍趋于滞后,新兴服务业发展较好.空间结构分量上,传统服务业由优势转为劣势;新兴服务业中金融业结构优势稳定,房地产业和其他服务业结构优势不足.空间竞争分量上,传统服务业竞争优势下降,而新兴服务业竞争优势不断增强.两类服务业的结构与竞争优劣势区域演变差异在扩大,传统服务业综合优势区及单一优势区数量少于新兴服务业.Takeing Huaihai Economic Zone as an example,the spatial shift-share model(SSSM)is used to study the trends and characteristics of service industry evolution from 2005 to 2019.In the research period,the actual growth rate of the service industry as a whole was higher than the growth rate of the share,the range of regions with aboveaverage service industry development expanded rapidly,the development of traditional service industry generally tended to lag behind,while the development of new service industry was better than that of the traditional.On the spatial structure component,the advantage of spatial structure component of traditional service industry turned to be inferior,among emerging service industry,the structural advantage of financial industry was stable,and the structural advantage of real estate industry and other service industries were insufficient.On the spatial competition component,the competitive advantage of traditional service industry is decreasing,while the competitive advantage of emerging service industry was increasing.The difference between the regional evolution of structural and competitive advantages and disadvantages of two types of service industry was expanding,and the number of integrated advantage areas and single advantage areas of traditional service industry was less than that of emerging service industry.
