| 摘要： | 目的：研究我国医药制造业产业的空间分布特点。方法：依据上市公司的公开数据，应用社会网络分析法对我国医药制造业上市企业数据进行网络密度分析（包括整体网络密度和个体网络密度）、网络中心性分析、凝聚力分析、核心-边缘分析及讨论，并提出建议。结果与结论：截至2015年9月30日，全国A股上市医药制造业上市企业共168家。通过应用社会网络分析软件分析发现，我国医药制造业空间城市关联网络密度为0.021 0，网络还很分散，其中北京、天津、上海构成的个体网络最大；网络中心性分析中，整体网络的点出度为1.604％、点入度为1.761％，北京的点出度和点入度都居于前列，北京、上海、天津、深圳的中间中心度较高，北京、天津、上海、昆明、深圳、广州的特征中心度较高；凝聚力分析结果较为复杂，网络中的城市可以分为8个子群；整体网络表现出较为明显的核心-边缘特征。可见，我国医药产业的发展需要注意通过发挥产业中心城市的辐射带动作用，推动区域产业协同发展，形成产业集聚网络，以推进我国医药制造业的协同发展。 |
| ABSTRACT： | OBJECTIVE： To study the spatial distribution characteristics of pharmaceutical manufacturing industry in China. METHODS： According to public data of listed company， social network analysis method was used to analyze the data of listed companies in China’s pharmaceutical manufacturing industry in respect of network density analysis （including overall network density and individual network density）， network centrality analysis， cohesion analysis， core-edge analysis. The discussion and suggestion was put forward. RESULTS & CONCLUSIONS： As of Sept. 30th， 2015， there were 168 listed companies of national A share listed pharmaceutical manufacturing industry. Analysis of social network analysis software showed that the density of spatial city association network in China’s pharmaceutical manufacturing industry was 0.021 0， and the network was also much dispersed， among which Beijing， Tianjin and Shanghai had the largest individual network. In network centrality analysis， the point outdegree of the whole network was 1.604％ and the point indegree was 1.761％. The point outdegree and point indegree of Beijing were all in the forefront. The betweenness centrality of Beijing， Shanghai， Tianjin and Shenzhen was in high level relatively， and the eigenvector centrality of Beijing， Tianjin， Shanghai， Kunming， Shenzhen and Guangzhou was in high level relatively. Results of cohesion analysis were more comprehensive， the cities in the network could be divided into 8 subgroups. The whole network showed a more obvious core-edge feature. So， the coordinated development of China’s pharmaceutical manufacturing industry can be promoted by paying attention to play radiation driving role of industrial center city， promoting coordinated development of regional industry and forming industrial agglomeration network. |
