中国生产性服务业的空间聚集与变化--基于285个城市的实证研究

Spatial Agglomeration and Change of Producer Service Industry in China——Based on the Empirical Study of 285 Cities

现有研究表明的我国生产性服务业存在明显的空间集聚特征,是基于国土空间上的城市集聚,但需作进一步的行业细分和实证。采用空间统计标准差椭圆方法,以我国285个城市的区位空间为足迹空间,从连续空间上大规模聚集角度计算和分析生产性服务业及其细分行业的空间聚集程度和变化趋势。结果表明:中国生产性服务业在空间分布上并没有呈现出显著的聚集性,没有形成"中心—外围"结构;2003-2014年,中国生产性服务业空间聚集程度提高,呈现集中化聚集发展趋势,聚集经济在生产性服务业发展中仍然发挥着主导作用;生产性服务业与其细分行业空间聚集程度的一致性较高,分布椭圆均呈"东北—西南"方向,信息传输、计算机服务和软件业聚集程度最高,交通运输、仓储和邮政业聚集程度最低,总体呈现"递增型"、"递减型"、"稳定型"三种变化趋势。

The existing research shows that the obvious spatial agglomeration of producer services industry is based on urban agglomeration of national land in China. Using the standard deviation ellipse, this paper analyses the space aggregation degree and change trend of producer service industry from a continuous mass gathering space based on geographical space of the 285 cities in China. The results indicate that the spatial aggregation of producer service industry is not obvious, and the center - periphery structure does not form ; 2003 -2014, the aggregating degree of producer services industry improved, and aggregating economy continues to play a leading role in the development of producer services industry; producer service and its subdivision industry gather in high degree of coincidence, and their distribution ellipses show northeast - southwest direction; The space aggregation degree of information transmission, computer services and software industry is the highest, while transportation, storage and postal industry is the lowest; Generally, the space aggregation of subdivision industry has three trends： increasing, decreasing and stable.
