摘要
【目的】探索资源型城市知识基础演化规律,揭示创新合作对其演化的驱动机理,以期为此特殊类型地区突破资源路径依赖、因地制宜发展新质生产力提供有益思路。【方法】以中国90个地级资源型城市为研究样本,基于2001—2021年发明专利申请数据,从规模、质量、结构和分蘖4个维度考察知识基础的动态演化过程,从本地、城际和跨国3个空间尺度探讨创新合作的多维驱动作用。【结果】(1)研究期内,知识规模非线性快速增长;知识质量的广度和深度逆向变化,前者升、后者降,优势知识成“簇”分布且自然资源指向鲜明;知识结构的相关和非相关多样化协同演进,所处生命周期阶段、地理区位和资源丰裕度决定了城市在波士顿矩阵中的位置;知识分蘖以知识进入为主,新知识的非相关多样化特征明显并触及先进前沿领域。(2)知识基础各维度均呈再生型>成熟型>衰退型>成长型、东部>中部>西部>东北、矿产型>其他>森工型的差异格局,其中知识宽度、相关和非相关多样化与全国平均水平的差距在缩小,但其他维度差距趋于扩大。(3)创新合作日趋频繁,合作对象由Ⅰ级城市(北、上、广、深)主导演变为多层级均衡。本地合作增强知识分蘖活跃度,却不利于知识质量提升和结构优化;城际合作能促进知识分蘖,但仅Ⅰ级城际合作略微增强知识独特性;跨国合作对知识多样化具有抑制作用。【结论】资源型城市知识规模逐渐扩大,但知识质量低、知识结构差且新知识进入困难。未来需加强本地能力建设、重视本地和城际创新合作协调互动、促进产业和知识耦合、正视相关和非相关多样化关系。
[Objective] This study aimed to explore the pattern of change of knowledge base in resource-based cities and analyze the driving effect of innovation cooperation,so as to provide some guidance for these type of areas to develop new quality productivity in accordance with local conditions and break their path dependency.[Methods] Based on a sample of 90 resource-based cities at the prefecture level,this study investigated the dynamic change process of knowledge base from the perspectives of scale,quality,structure,and branching,and examined the driving effect of innovation cooperation from local,cross-city and transnational spatial scales,using the data of invention patent applications from 2001 to 2021.[Results](1) The scale of knowledge grew rapidly and non-linearly.The breadth and depth of knowledge changed inversely,with the former increasing and the latter decreasing.Dominant knowledge distributed in clusters and showed a clear orientation towards natural resources.The related and unrelated diversification of knowledge evolved synergistically,and the position of a city in the diversification Boston matrix was determined by its life cycle stage,geographical location,and resource endowments.Knowledge branching was dominated by new knowledge entry,which had significant features of unrelated diversification and touched on advanced frontier areas.Each dimension of the knowledge base showed the same differentiation pattern of regenerating city > mature city > declining city >growing city,eastern city > central city > western city > northeast city,and mineral city > other types > forestry city.Each dimension index of resource-based cities' knowledge deviated from the national average significantly.Specifically,knowledge breadth,unrelated diversification,and related diversification showed a catch-up trend,while the gaps in other dimensions tended to widen.(3) Innovation cooperation was becoming increasingly more frequent,and the cooperation partners evolved from level I city(Beijing,Shanghai,Guangzhou,and Shenzhen) d
