省际边界区县域产业结构时空演变及影响因素——以晋陕豫黄河金三角地区为例

Spatial-Temporal Evolution and Impacting Factors on Industrial Structure of Counties in Interprovincial Border Areas:Taking the Golden Triangle Area in the Yellow River in Shanxi Shaanxi and He'nan Provinces as an Example

选取2005,2010和2016年晋陕豫黄河金三角地区各县域统计数据,计算产业结构提升系数,揭示县域产业结构时空演变的基本特征,并利用地理探测器分析产业结构演变的影响因素。结果表明:2005—2016年,研究区产业结构水平整体处于提升状态,且阶段性特征显著;产业结构水平有明显的空间集聚特征,且产业结构高水平的县域呈“C型”包围低水平县域的态势,被包围地区基本处于紧邻省界线的县域和中心地带,深刻反映出省际边界地区的“切变”效应对产业调整的影响;产业结构演变是人口、市场和技术等因素的综合表现,整体而言,人口和市场要素对研究区产业结构演变的影响力较高,不同自然单元分区的主导因素存在差异,在区域合作的背景下,初步呈现出区域内在动力向外部要素转变的特征。

In this paper,an index of industrial structure upgrading was established based on the statistical data of the counties in the Golden Triangle of the Yellow River in Shaanxi,Shanxi,Henan Provinces in 2005,2010 and 2016,so as to reveal the basic characteristics of the spatial and temporal evolution for the industrial structure at the county level.And geographic detectors were employed to analyze impacting factors of industrial structure evolution.Our results indicate that,firstly,from 2005 to 2016,the industrial structure level of the studied area was in an upgraded state as a whole,and the stage characteristics were significant.It was mainly reflected in the period of 2010—2016,and the industrial structure level showed a rapid upward trend.Secondly,the level of the industrial structure displayed apparent characteristics of spatial agglomeration,and the counties with high industrial structure exhibited a state of“C-type”surrounding low-level counties.The encircled areas were basically located in counties and central areas adjacent to provincial boundaries,which profoundly reflected the impact of the“shear”effect on industrial adjustment in provincial boundaries.Lastly,the evolution of industrial structure was a comprehensive manifestation of influences in population,market and technology.Overall,population and market factors had a high impact on the evolution of industrial structure in the studied area.There were differences in terms of leading factors of different natural unit zones.Under the background of regional cooperation,the characteristics of the transformation of regional internal power to external factors were preliminarily presented.In summary,to optimize the allocation of resources and achieve sustainable development,the studied area should break the administrative barrier and change the management style from decentralized adjustment to regional cooperation.
