兰州-西宁城市群工业集聚格局及其影响因素空间溢出

The spatial pattern and spatial spillover of its influencing factors in the industrial aspects of Lanzhou-Xining urban agglomeration

采用空间统计方法和空间计量模型分析2005-2018年兰州-西宁城市群工业集聚格局及其影响因素的空间溢出.结果表明,工业集聚呈现“中心-外围”空间格局和“点-轴”发展特征,工业集聚的空间非均衡格局存在马太效应.工业集聚具有空间相关性,热点区及次热点区主要集中在兰州-西宁城市群“中心”的工业优势县(区);工业集聚冷点区及次冷点区主要集中在兰州-西宁城市群“外围”的工业待发展县(区).工业集聚及其影响因素均存在空间溢出性,相邻县(区)工业集聚对本县(区)工业集聚具有促进作用;人口密度、经济水平、政府干预、市场化率、投资水平等因素对本县(区)工业集聚产生影响时也通过空间溢出对相邻县(区)工业集聚产生影响.

The spatial analyzing technology and spatial econometric model were used to analyze the spatial pattern and spatial spillover of its influencing factors in the industrial aspects of Lanzhou-Xining urban agglomeration from 2005 to 2018.The results showed that,the industrial agglomeration had the spatial pattern of center-periphery and development characteristics of point-axis.There was Matthew effect in the spatial imbalance pattern of industrial agglomeration.Industrial agglomeration had a positive spatial correlation,and its hot spots and sub-hot spots were mainly concentrated in the industrial superior counties of Lanzhou-Xining urban agglomeration,and the cold spots and sub-cold spots were mainly concentrated in the industrial underdeveloped counties of Lanzhou-Xining urban agglomeration.Industrial agglomeration and its influencing factors had spatial spillover characteristics.County-level industrial agglomeration was promoted by the industrial agglomeration of neighboring counties.When population density,economic level,government intervention,market rate,investment level and other factors affected the industrial agglomeration of the county,they also affected the industrial agglomeration of adjacent counties through a spatial spillover.
