采用核密度分析法、圈层分析法、GIS空间分析技术与杭州市工商登记数据探讨杭州生产性服务业空间格局与演变特征。结果表明:生产性服务业主要集中于中心城区,公司数量整体上由中心地区向周边地区呈圈层递减的态势,少数行业的外围地区数量较多。高密度区基本在中心城区成片集聚,不同行业高密度区存在空间分异与趋同现象。空间格局演变分析反映:各类行业既有向心集聚,又有不同程度的向外扩展趋势,但它们向心集聚与对外扩张特点不同,部分行业新增企业高密度空间一致。关联、集聚、规划引导机制推动生产性服务业空间格局演变。目前部分地段存在写字楼供需不匹配问题,亟需解决写字楼过度空置问题。
Using the methods of nuclear density analysis, circle analysis, GIS spatial analysis and Hangzhou business registration data, this paper discusses the spatial pattern and evolution characteristics of producer services in Hangzhou. The results show that productive service industry is mainly concentrated in central urban area, with the number of companies decreasing from the central area to the surrounding areas as a whole. The number of peripheral areas in a few industries is relatively large. High-density areas are basically agglomerated in central urban areas, with high-density areas of different industries having spatial differentiation and convergence. The evolution of spatial pattern reflects that all kinds of industries have both agglomeration and outward expansion in varying degrees. However, their characteristics of agglomeration and outward expansion are different, and the high-density space of some newly-added enterprises in some industries is consistent. Relevance, Agglomeration, Planning and Guiding Mechanism to Promote the Spatial Pattern Evolution of Producer Services. At present there are some locations do not match the supply and demand of office space, the urgent need to solve the problem of excessive vacancy office space.
