东营石油装备制造业创新网络演化研究

采用社会网络分析方法,借助Ucinet、ArcGIS等软件工具,从多维邻近的视角出发,对东营石油装备业创新网络演化进行分析研究,研究发现：首先,多维邻近对东营创新网络发展产生了重要影响,且不同网络发展阶段（培育、起步、成长）主导的邻近因子不同。这一方面证实了Boschma多维邻近性的相关理论假说,另一方面指出多维邻近因子与东营创新网络演变的不同关联。其次,高校、大型国有企业是东营创新网络的知识源泉和组织者。中国石油大学（华东)、胜利油田集团企业发挥了主导作用,这与国外中小型创新企业发挥主导作用的情形有很大差异。

Innovation Network Evolution of Petroleum Equipment Manufacturing Industry in Dongying

Based on information data of patent applying and cooperative patent of petroleum equipment manufacturing industry in Dongying during 1985-2013, patent information service platform of SIPO and the data, the author interviewed 17 petroleum equipment manufacturing industry in Dongying, and did an analytical research on innovative network evolution of Dongying petroleum equipment manufacturing industry from multidimensional proximity perspective with social network analysis in virtue of software tools such as Ucinet, Arcgis etc. Then we get some result. Firstly, multidimensional proximity factor has great influence on Dongying innovative network development and the predominant proximity factor is different on different network development stages. In breeding stage, the cooperation between network main bodys mainly in enterprises belong to state-owned Shengli Group in which organization is proximity to predominant factor; in early stage, cooperation mainly occurs in enterprises having industry chain cooperation relationship which in order to reduce communication transportation costs which become the consensus of cooperation main body when geographic proximity factor become dominant; in growth stage, cooperation occurs mainly in enterprises with similar technical level knowledge foundation which in the pursuit of horizontal cooperation when cognitive proximity factor plays a leading role. On the one hand, that confirms relevant multidimensional proximity theoretical hypothesis of Boschma, and points out different relevance between multidimensional proximity factor and Dongying cooperative innovative network evolution on the other hand. Secondly, universities and large state-owned enterprises are knowledge source and organizers of Dongying innovative collaborative networks. China University of Petroleum (East China) and Shengli Oilfield conglomerate plays a leading role which is different with the foreign situation that small and medium-sized enterprises play a leading role.
