摘要:

公司内部网络研究是当前城市经济网络研究的重要内容。本文利用2005、2010年长三角A股上市公司企业网络数据库,运用社会网络分析方法、位序—规模分析法等,分析了2005、2010年长三角城市网络空间结构演变及其主要影响因素。研究发现:① 长三角上市公司总部沿沪宁—沪杭—杭甬Z字形轴线集聚,从一主(上海)二副(杭州、南京)三中心向一主(上海)三副(杭州、苏州、南京)四中心空间结构演变;苏州超过南京成为第三大企业总部集聚中心。② 长三角城市网络核心—边缘结构整体延续,Z字形轴线城市维持核心地位,具备强大的网络权力与威望。③ 长三角城市网络除等级扩散、邻近扩散等特征之外,还具有明显的行政地域性。主要体现在省会南京、杭州分别成为江苏、浙江省内外上市公司子公司的重要据点;尤其是南京凭借省会优势,中心度仍然高于总部职能较强的苏州。④ 在长三角经济一体化背景下,跨行政地域性的联系有所加强,特别是上海、苏南向苏中、苏北的扩散明显;浙西南仍是网络相对封闭、孤立的地带,中心度相对较低。⑤ 行政等级和区划,市场容量等是长三角城市网络空间结构的主要影响因素,而到上海高速公路时间距离、劳动力成本和土地成本的影响在统计上未通过显著性检验。

Abstract:

In this study, we created 2005 and 2010 A-share listed companies network database of the Yangtze River Delta and used social network analysis and rank-size analysis methods to analyze the spatial structure of urban network in the Yangtze River Delta. The result shows that: (1) The Yangtze River Delta listed companies' headquarters tended to agglomerate in the Shanghai-Hangzhou-Ningbo Z-shaped corridor. The most important change of the spatial structure of company headquarter distribution during the study period was the development from three centers to four centers. Suzhou replaced Nanjing and became the third largest hub of company headquarters, after Shanghai and Hangzhou; (2) Urban network structure maintained a core-periphery pattern. Cities along the Z-shaped corridor showed higher centrality and have strong influences on the spatial pattern of the urban network; (3) The network structure showed hierarchical diffusion, neighborhood diffusion, and administrative constraint characteristics. The provincial capitals Nanjing and Hangzhou of Jiangsu and Zhejiang provinces became major investment stronghold only after Shanghai. Nanjing's network centrality was higher than Suzhou because of its higher administrative status; (4) In the background of the Yangtze River Delta economic integration, cross-regional linkages has been strengthened, especially the diffusion of companies from Shanghai and Southern Jiangsu to Central and Northern Jiangsu was very clear. Centrality of Southwest Zhejiang was relatively low. The area was still relatively isolated within the network; (5) Administrative status and divisions and market scale were the main factors affecting the spatial structure of urban network in the Yangtze River Delta. The impact of temporal distance to Shanghai by express way, labor costs, and land costs were not statistically significant.

Key words: urban network, social network analysis, A-share listed companies, spatial structure, the Yangtze River Delta(YRD)
