中国数字创意上市挂牌企业空间格局及其影响因素     

展亚荣  谷人旭 《地理科学》2022,42(8):1370-1380

基于中国数字创意上市企业、新三板挂牌企业数据,运用核密度估计、标准差椭圆、基尼系数、负二项回归模型等方法探究其空间分布特征及影响因素。研究发现：① 数字创意上市挂牌企业总体呈“东密西疏”的空间结构特征,集聚与扩张共存并以集聚为主,且始终保持京津冀、长三角、珠三角等多核心空间集聚形态,空间分布高度不均衡且区域重心北向迁移显著。② 数字创意上市挂牌企业空间分布具有行业异质性,其集聚区域、集聚强度因产业特性和所有制性质不同而存在差异。③ 数字创意上市挂牌企业的空间分异受到集聚经济、基础设施、正式制度、非正式制度因素中的文化活跃度与企业家创新精神、宏观经济环境因素中的全球连通性、金融集聚水平等因素影响,具有明显“高等级城市偏好”。企业空间分异影响因素因产业特性和所有制不同存在差异。  相似文献

殷汉琴  简中华  魏迎春 《物探与化探》2014,(1):135-141

分析了浙中某地2 300个表层土壤样品中8类重金属元素的含量,并与1987年区域化探数据比较,发现Cd、Hg、Pb、Cr、Ni、Cu、Zn等重金属出现了显著升高,升高的区域与工业区分布吻合。研究区内大约6.09%的土壤受重金属中—重程度的污染,40.26%的土壤达到轻污染,污染区的分布主要与交通干线和五金企业聚集区吻合,而与地质背景无关,表明研究区重金属污染主要来源于五金企业。  相似文献   

CHINA＇S REGIONAL DISPARITY IN 1981-2000：OPENNESS AND DEVELOPMENT OF NON-STATE-OWNED ENTERPRISES AND FISCAL DECENTRALIZATION     

SHENBing 《中国地理科学(英文版)》2004,14(2):97-103

While China‘s economic growth has been impressive since 1978, regional disparity in terms of provincial per capita GDP has been increasing. On the other hand, this rapid but uneven growth was accompanied by China‘s deepening openness and structural reforms including the development of non-state-owned enterprises (non-SOEs) and fiscal decentralization. Based on quantitative analyses, this paper tries to explore the features of regional disparity in China and the relationships between regional growth and China‘s openness and economic structure reforms in the period from 1981 to 2000, The paper finds that the catching-up of the coastal region to the initially rich provinces, which are mainly located in inland areas, brought about a convergence of the growth pattern across provinces in the 1980s. The subsequent divergence in the provincial growth rates between the coast and the interior generated an enlarging regional disparity in China in the 1990s. The ever-faster growth in the coastal region was benefited by China‘s openness and the development of non-state-owned enterprises. The development of non-state-owned enterprises underlies the higher operational efficiency in the coastal region. Additionally, with the insignificant regression results, fiscal decentralization was observed to facilitate faster growth in the coast region. The findings justify the initiative of the “West Region Development Strategy“ and offer some policy implications for China.  相似文献   

CEO空间经历对中国民营企业500强总部区位选择影响分析     

王丽敏  吴相利  刘凡  张少铎 《世界地理研究》2023,32(1):67-79

以我国民营企业500强为研究样本,基于2005、2011、2018年企业总部数据和CEO空间经历数据,运用ArcGIS 10.2软件进行空间可视化分析,揭示中国民营企业总部的空间格局特征,并解释了CEO的空间经历与企业总部区位布局之间的地理空间关联。研究发现：(1)我国民营企业500强总部主要分布在长三角、京津冀以及珠三角等沿海3大城市群,呈现高度密集分布特征。(2)我国民营企业500强总部主要集聚在高行政级别的城市,即集中在直辖市、副省级和省会城市。(3)从CEO空间经历与民营企业500强总部布局的地理空间关联来看,CEO的出生地、就学地与企业总部所在地在城市、省域及区域空间尺度上相同的比重较高,关联性显著。其中,CEO最后学历就学地相同数占比均达到30%以上;但不同行业关联性差异明显,制造业CEO最后学历就学地和企业总部位于同一座城市的比重小于其他产业,关联性相对较弱。  相似文献   

Spatial distribution and the scale effect of influencing factors of specialized and sophisticated enterprises that produce new and unique products in the Yangtze River Delta region: Based on the buffer and MGWR analyses北大核心CSCD     

丁建军  胡定国  冷志明 《地理科学进展》2023,(11):2099-2112

High-quality cultivation of specialized and sophisticated enterprises that produce new and unique products is an important starting point for consolidating the security foundation of China's industrial chain and supply chain. Using buffer zone analysis and the multi-scale geographically weighted regression (MGWR) model, this study explored the spatial distribution of specialized and sophisticated enterprises that produce new and unique products in the Yangtze River Delta region and influencing factors in 2021. The study found that: 1) Spatially, Shanghai is the main area where specialized and sophisticated enterprises that produce new and unique products are concentrated, followed by provincial capitals and cities on the coast and along rivers; The overall composition of the industry is unbalanced, and the real economic industries such as machinery and equipment manufacturing and high-tech manufacturing account for a relatively high proportion, but there are differences in different regions. 2) In terms of spatial agglomeration, differences between circles and the scale effect are obvious. Within each province, the spatial distribution of specialized and sophisticated enterprises that produce new and unique products in different cities is uneven. Region-wide, the overall spatial distribution pattern of "one pole and multiple cores" is evident. Shanghai is the main agglomeration area for these enterprises, and the provincial capital cities and cities that are the regional economic centers are the secondary agglomeration areas of these enterprises. 3) The four dimensions of influencing factors—physical geography, government, market, and society—have a scale effect on the spatial distribution of specialized and sophisticated enterprises that produce new and unique products. The degree of land development acts at a small scale, which is a local variable, and shows a large difference in the impact on the spatial distribution of these enterprises across the region. Factors such as elevation, government-business relationship, degree of marketization, number and scale of enterprises, degree of openness, logistics development level, and innovation environment are global variables, and except that the degree of marketization and the number of enterprises have a significant negative impact on the spatial distribution of these enterprises, the impact of all other factors is significantly positive. The research results can provide support for the optimization of the layout of new special expertise enterprise space in the Yangtze River Delta region, in order to provide reference for the formulation of new special expertise policies and industrial planning. © 2023, Editorial office of PROGRESS IN GEOGRAPHY.

上海日资纺织服装制造企业的空间格局   总被引：2，自引：0，他引：2  

姜海宁  张文忠  吕国庆  马仁锋  余建辉 《地理研究》2016,35(6):1095-1106

选择上海作为研究区域,以日资纺织服装制造企业名录为数据基础,运用GIS软件,分析1995-2012年上海日资纺织服装制造企业的空间分布规律及其影响因素。结果发现：企业集聚与扩散并存,并向郊区化发展,其中开发区是企业集聚的重要空间载体,并沿高速、高架路呈带状分布,其集聚强度和规模随时间推移迅速增大;外商独资企业与合资合作企业的集聚格局相似,中心依赖性较弱,而大规模企业倾向于集聚在郊区,小规模企业中心依赖性较强。运用泊松回归模型的计量结果表明,接近高速或高架路因素对企业具有显著吸引作用,其次是开发区、集聚因素及地价因素影响也较大,高等院校影响相对较小,而其他4个因素作用并不明显。此外,与合资合作企业相比,外商独资企业的区位选择对集聚效应、开发区以及高等院校更加敏感,而受地价、接近高速高架路等影响相对较小。  相似文献   

China′s urban network based on spatial organization of electronic information enterprises     

《地理研究》2012,31(2)

通过分析国内外城市网络研究的理论与方法,基于电子信息企业生产网络视角,对中国城市网络的空间特征进行了探索。研究发现：在中国制造业企业500强和世界500强中,电子信息企业总部集中于以北京、上海和深圳为核心的三大沿海都市圈,以及中西部地区的特大城市和省会城市,其研发机构与总部区位特征具有一定相似性,生产基地分布相对分散。由中国企业和跨国公司所主导的中国城市网络,可划分为地方化和全球化两种类型,均以东部及中西部特大城市为网络核心节点。地方化型城市网络的企业总部节点城市较为分散,网络密度和连接度较小;全球化型城市网络则以北京和上海为核心节点,对外联系程度相对较高。与传统城市等级体系相比,城市网络体系具有更强的包容性,从中可以发现崛起中的专业化城市。  相似文献
