兰州市生产性服务业的空间集聚及其影响因素

The Spatial Agglomeration Characteristics and Its Influencing Factors of Producer Services in Lanzhou

依据兰州市2016年工商企业登记数据,运用基于距离的产业集聚研究方法,分析了兰州市生产性服务业的空间布局、集聚特征及其影响因素。结果表明:兰州市生产性服务业空间分布不均衡,自东向西依次为中心高密度地带、过渡地带、扇形低密度地带,呈现出'圈层+扇形'的空间结构特征;从不同行业来看,金融保险业、计算机应用服务业及交通运输、仓储和邮政业集聚趋势更为明显,而房地产业、租赁和商务服务业、科学研究和综合技术服务业的集聚趋势较弱,并且除金融保险业呈现出多中心的集聚特征外,其余行业都是单中心集聚;就不同规模而言,较大规模企业的集聚范围较大但集聚程度较弱,而较小规模企业的集聚范围较小但集聚程度较强,成为兰州市生产性服务业空间集聚的主导力量;城市功能分区、地价租金水平、交通便捷程度、办公空间分布是影响生产性服务业空间集聚的重要因素。

Based on the business registration data of enterprises in Lanzhou City in 2016,using the distance-based industrial space agglomeration measurement method,the spatial layout,agglomeration characteristics and formation mechanism of the production service industry in Lanzhou City were analyzed.The results show:the spatial distribution of the productive service industry is uneven,showing the characteristics of'East Mississippi',forming a'circle+fan'pattern that gradually decreases from the center to the periphery;There are significant differences in the characteristics of agglomeration among industries.The computer application service industry,the financial and insurance industry,and the transportation,warehousing and postal industries have a clear trend.The real estate industry,scientific research and integrated technology services,leasing and business services are in a weaker trend.The large-scale enterprises have a low degree of agglomeration and the agglomeration trend is not obvious.The smaller-scale enterprises dominate the spatial agglomeration of the productive service industry in Lanzhou with their higher concentration;Urban functional zoning,land price and rent level,convenient transportation and office space distribution are important factors affecting the spatial agglomeration of producer services.
