中国科技服务业集群识别与多层次创新网络演化

Cluster Identification of China's Science and Technology Service Industry and the Evolution of Multi-level Innovation Network

在实践领域中已出现科技服务业集群多层次创新网络嵌入现象,使用区位熵识别出23个科技服务业集群,以2001—2017年有效合作发明专利数据为基础,通过卡方检验,发现科技服务组织在专利合作申请人的选择上存在显著的区位差异,运用UCINET软件直观展示中国科技服务业集群多层次创新网络的网络模式与空间演化特征。结果表明,中国科技服务业多层次创新网络的重要载体是集群;多层次创新网络具有度分布不均匀性、空间分布非均衡性特征;且呈现出多集群、跨区域、多尺度的“核心-边缘”的空间格局。研究结论为政府政策的制定和科技服务集群企业构建最佳空间尺度的创新网络提供参考。

In practice,there has been a phenomenon of multi-level innovation network embedding in science and technology service industry clusters,and 23 science and technology service industry clusters have been identified by using location entropy in this paper.Based on the data of effective cooperative invention patents from 2001 to 2017,through chi-square test,it is found that there are significant regional differences in the selection of patent partners among science and technology service organizations.Furthermore,using UCINET software,the network model and spatial evolution characteristics of multi-level innovation network of China's science and technology service industry cluster are visually displayed.The results show that cluster is an important carrier of multi-level innovation network of China's science and technology service industry;the multi-level innovation network is characterized by uneven degree distribution and unbalanced spatial distribution;a multi cluster,cross regional and multi-scale"Core-Periphery"spatial pattern is formed.The research conclusions provide theoretical suggestions for the formulation of government policies,and provide practical reference for science and technology service cluster enterprises to build the best spatial scale innovation network.
