摘要
创新是引领发展的第一动力,网络是创新成功的关键。文章基于2000—2017年中国沿海地区海洋产业合作专利数据,运用复杂网络分析、ArcGIS空间分析和地理探测器等方法,构建海洋产业合作创新网络,分析合作网络的特征、结构及邻近性机制得出:①沿海地区海洋产业合作专利经历萌芽和探索阶段,现在正处于高速发展阶段,但部分省的合作专利贡献率不足。②创新主体中心节点带动辐射能力与合作能力增强,高校是合作创新的主力军。以企业为中心的海洋技术创新体系尚未形成,企业创新生态环境有待完善。③海洋产业合作创新网络结构的广度扩张,有明显的合作团体出现,但网络整体通达性弱,结构松散、不稳定。④城市间趋于向更多、更广的范围拓展合作,上海市、青岛市、天津市、广州市与其他各城市联系较强,北京市引领创新能力逐渐凸显。⑤社会邻近性对海洋产业合作创新网络的解释力最高,且两两邻近性之间对城市间合作率的交互影响呈现双因子或非线性增强关系。
Innovation is the first driving force to lead the development,and the network is the key to innovation.Based on the cooperative patents of marine industry in coastal areas of China from 2000 to 2017,this paper constructs cooperative innovation network of marine industry and analyzes its characteristics,structure and proximity mechanism by complex network analysis,ArcGIS spatial analysis method and Geodetector,etc.The results show that:1)Cooperative patents of marine industry in coastal areas,experiencing,the germination and exploration stages,are at the stage of rapid development,but it presents insufficient contribution rate of cooperative patents in some provinces.2)The central node of innovation subjects drives the radiation capacity and enhances the cooperation ability,universities are still the main force of cooperative innovation.However,the enterprise-centric marine technology innovation system has not yet been formed,and it needs to improve the innovative ecological environment of enterprises.3)The structure of cooperative innovation network of marine industry has expanded in breadth and facilitates the emergence of cooperative groups,but the overall accessibility of network is weak and the structure is loose and unstable.4)Cities tend to expand cooperation with others in more and wider areas.It has strong connections with other cities in Shanghai,Qingdao,Tianjin and Guangzhou,and the innovation ability in Beijing plays leading role.5)Social proximity has the highest explanatory power for cooperative innovation network of marine industry,and the interaction of proximity on the cooperation rate between cities is a kind of bi-factor or non-linear enhancement relationship.
