我国智能制造装备产业专利合作网络演化分析

Evolution Analysis of Patent Cooperation Network in China’s Intelligent Manufacturing Equipment Industry

基于2001—2020年我国智能制造装备产业合作专利数据,利用社会网络分析法构建专利合作网络,分析揭示网络主体及其空间演化规律。结果显示:(1)我国智能制造装备产业专利合作网络规模逐渐壮大,网络具有较强的知识交换和信息传输能力但是传递效率较低;部分创新主体之间已经建立起稳固的合作关系,网络向复杂化和社区化发展。(2)在不同产业生命周期,网络主体演化存在着较大差异并呈现出多元化合作发展趋势;现阶段,国家电网公司等电力企业和研究机构成为推动智能制造装备产业发展的核心。(3)区域内部专利合作比例整体上不断提升,其中广东和上海的区域内部专利合作比例较高,区域边界对其专利合作的影响逐渐增强。(4)在跨区域专利合作网络中,北京处于核心位置且地位不断巩固;北京、江苏、广东扮演"高重要性-高协调性"的角色,不仅是信息交流的中心,也是其他区域之间的桥梁。研究启示为:应合理配置科技创新资源,保障各区域智能制造装备产业合作创新均衡发展,形成国内智能制造装备产业合理的空间布局。

Based on the cooperation patent data of intelligent manufacturing equipment industry in China from 2001 to 2020,this paper constructs patent cooperation network by using social network analysis method to reveal the main body and spatial evolution of the network.The results show that:(1)The scale of patent cooperation network of intelligent manufacturing equipment industry is gradually expanding,the network has strong knowledge exchange and information transmission capacity,but the transmission efficiency is low.Some innovation subjects have established solid cooperation relationship in the network,and the network is becoming complex and community.(2)In different industrial life cycles,there are great differences in the evolution of network subjects and presenting a diversified cooperative development.At the present stage,State Grid Corporation of China and other power enterprises and research institutions have become the core of promoting the development of intelligent manufacturing equipment industry.(3)The proportion of intra-regional patent cooperation is increasing on the whole,and the proportion of intra-regional patent cooperation is higher in Guangdong and Shanghai,the influence of regional boundaries on their patent cooperation is gradually enhanced.(4)In the inter-regional patent cooperation network,Beijing is in the core position and its position is constantly consolidated;Beijing,Jiangsu and Guangdong play the role of"high importancehigh coordination",not only as the center of information exchange,but also as a bridge between other regions.The implications of the study are as follows:scientific and technological innovation resources should be rationally allocated to ensure the balanced development of cooperative innovation of intelligent manufacturing equipment industry in various regions,developing a reasonable spatial layout of domestic intelligent manufacturing equipment industry.
