中国半导体产业的空间集聚识别与集聚分区

Spatial Agglomeration Identification and Agglomeration Zoning of Semiconductor Industry in China

文章基于中国半导体企业—分支的投资关系,运用区位商、最小跨度树与模块度等复杂网络的图分割技术,构建涵盖256个地级及以上城市的中国半导体产业网络,并在分析其空间集聚特征和联系强度的基础上划分出一个可供参考的中国半导体集聚区分区方案。研究发现:(1)中国半导体产业呈现集聚为主的空间分布模式,集聚水平呈现出东高西低、南高北低非均衡发展态势。(2)全局对外投资网络的地理分布呈现为钻石结构与菱形模式。全局本地投资集聚区表现为显著的东西差异,东部本地集聚区为双核或多核牵引型,西部本地集聚区表现为单核牵引型。(3)在全国6大区域集聚区中,长三角的区域一体化水平最高,珠三角域内联系强度密集但珠江东岸的极化现象显著,京津冀表现为梯度双核驱动模式,山东半岛依托济南与青岛都市圈形成横向联系,关中与成渝地区表现为双核增长极集聚区模式。(4)中国半导体产业的空间集聚区可划分为南方、东部、北方和西部4个一级分区和20个二级分区。

Based on the investment relationship between Chinese semiconductor enterprises and their branches,this paper constructs China semiconductor industry network covering 256 prefecture-level cities using the methods of locational quotient,minimum spanning tree,and modularity,and analyzes its spatial agglomeration characteristics and connection degree.According to the above,it proposes a reference scheme for the agglomeration zoning of China's semiconductor industry.The findings include that:1) China semiconductor industry shows the characteristics of agglomeration distribution.The agglomeration level presents an uneven development trend,which is high in the east of China and low in the west of China,high in the south of China and low in the north of China.2) The global outward investment network exhibits a geographical distribution resembling a diamond structure and rhombus pattern.Local investment agglomeration areas show significant differences between the east of China and west of China,with the east of China having a dual-core or multi-core traction type,and the west of China displaying a single-core traction type.3) Among the six agglomeration areas,it demonstrates the highest level of regional integration in the Yangtze River Delta.It exhibits intensive connectivity within the region in the Pearl River Delta,but significant polarization is observed on the east bank of the Pearl River.The Beijing-Tianjin-Hebei region shows a gradient dual-core driving pattern,while the Shandong Peninsula relying on the Jinan-Qingdao metropolitan area forms horizontal connections.It presents a dual-core growth pole agglomeration pattern in the Central Shaanxi Plain and Chengdu-Chongqing area.4) The spatial agglomeration area of China's semiconductor industry can be divided into Ultimately,China is roughly divided into four primary zones( the southern zone of China,the eastern zone of China,the northern zone of China,the western zone of China) and 20 secondary zones.
