创新型城市环保产业技术合作网络动态演化路径研究--以广州为例

为探究创新型城市环保产业技术合作网络动态演化路径,以广州市为例,通过专利数据挖掘和社会网络方法构建创新型城市环保产业技术创新合作网络,分析合作网络结构和动态演化路径,揭示新旧节点间连接方式演化规律。结果表明,广州市环保产业技术创新合作网络中的创新主体之间联结松散,创新主体之间连接效率较低。华南理工大学、广东电网有限责任公司电力科学研究院、广州有色金属研究院、中山大学、广东工业大学等是合作网络的核心主体,企业创新能力相对乏力;广州市环保产业技术创新合作网络的演化路径表明创新合作发展迅速,合作网络向规模更庞大、关系更复杂的方向发展;创新主体进出网络的动态变化大,合作网络中创新主体之间的相互联系不稳定,创新网络未达到稳定平衡状态。

RESERCH ON DYNAMIC EVOLUTION PATH OF TECHNOLOGICAL COOPERATION NETWORK OF ENVIRONMENTAL PROTECTION INDUSTRY IN INNOVATION CITY--A CASE STUDY OF GUANGZHOU CITY

In order to explore the dynamic evolution path of technological cooperation network of environmental protection industry in innovative cities,this article takes Guangzhou as an example,constructing technological innovation cooperation network by integrating China's patent data mining and social network methods.The structure and dynamic evolution path of the cooperation network are analyzed,and the evolution law of the connection between the old and new nodes is revealed.The results show that the innovative subjects in the technological innovation cooperation network are loosely connected,and the connection efficiency between the innovative subjects is low.South China University of Technology,Electric Power Research Institute of Guangdong Power Grid Co.,Ltd.,Guangzhou Research Institute of Nonferrous Metals,Sun Yat-sen University,Guangdong University of Technology,etc.are the core subjects of cooperation network,and the innovation ability of enterprises is relatively weak.The evolution path the technology innovation cooperation network indicates that innovation cooperation develops rapidly,and cooperation network is becoming larger and more complex.The relationship between innovation subjects is not stable,and the innovation network has not reached a stable equilibrium state.
