摘要

全球城市间开展光伏产业创新合作是全球能源绿色转型及可持续发展的重要基石，探讨其创新合作网络时空格局演变及中国城市地位变迁，对于战略性新兴产业的发展以及城市地位提升具有重要的战略意义。论文基于2000—2022年光伏产业专利合作数据构建全球1382个城市间创新合作网络，结合光伏产品技术生命周期，运用复杂网络分析方法探究了全球城市光伏产业创新合作网络的拓扑结构及空间结构演变，并揭示了中国城市的地位变迁规律。研究发现：① 伴随着光伏技术从初生萌芽到快速生长再到成熟稳定，全球光伏产业创新合作强度呈现从快速增长到回落稳定的变化趋势。② 全球光伏产业创新合作网络在空间上具有明显的集聚特征，主要集中在美国东部、欧洲西部以及东亚地区。创新网络从以美国、日本城市为中心的“少核主导”向“多核互联”演变，并逐渐演化为以中国、印度、欧美城市为主的创新集群。③ 城市规模以及城市创新等级对城市光伏产业合作创新规模具有显著的正向影响，碳减排政策初期对光伏产业创新推动作用较强，后期呈现边际效应递减效应。④ 以北京、上海、苏州、深圳等为代表的中国城市在网络中的中介中心度和加权中心度均呈持续上升态势，表明中国光伏产业正逐步转型：从初期依赖技术引进，发展到国内外技术互惠合作，进而成为技术输出者的转变。厘清全球光伏产业创新合作网络的时空演化以及中国城市地位的变迁，有望推动光伏产业链的重组和价值链的重新配置，优化区域创新活动的空间布局，进而重构战略性新兴产业的空间格局。

Abstract

Cooperative innovation in the photovoltaic industry among global cities is a crucial cornerstone for sustainable development worldwide. Examining the evolution of innovation cooperation networks among global cities and the changing status of Chinese cities holds significant strategic importance for the development of strategic emerging industries and the enhancement of cities' status. Based on the patent cooperation data from 2000 to 2022, this study constructed innovation cooperation networks among 1382 global cities. Considering the life cycle of photovoltaic products, and using complex network analysis methods, this study elucidated the topological structure and spatial change of the global intercity photovoltaic industry innovation cooperation networks. Then, the changing status of Chinese cities was revealed. The results show that: 1) With the technology of the photovoltaic industry evolving from nascent stage to rapid growth and then to maturity and stability, the intensity of global photovoltaic industry innovation cooperation first grew and then became stable. 2) The global photovoltaic innovation cooperation network exhibited a pronounced spatial clustering, primarily concentrated in the eastern United States, Western Europe, and East Asia. The innovation network has transitioned from a "few-core dominance" centered on cities in the United States and Japan to a "multi-core interconnected" structure, gradually evolving into innovation clusters dominated by cities in China, India, Europe, and the United States. 3) City scale and innovation level had a significant positive impact on the intensity of photovoltaic industry innovation cooperation of cities. The carbon reduction policy had a strong driving effect on photovoltaic industry innovation in the early stage, but later showed a diminishing marginal effect. 4) Cities in China, represented by Beijing, Shanghai, Suzhou, and Shenzhen, have shown a continuous upward trend in their betweenness centrality and weighted centrality within networks. They have gradually transitioned from primarily importing technology to establishing mutually beneficial relationships in technology with domestic and international partners, ultimately evolving into technology exporters. Understanding the spatiotemporal change of the global photovoltaic industry innovation cooperation networks and the changing status of Chinese cities within it holds significant promise. It is expected to promote the restructuring of the photovoltaic industrial chain and the reconfiguration of the value chain. This, in turn, can reshape the spatial pattern of strategic emerging industries and regional innovation activities.

Key words： global city; photovoltaic industry; innovation cooperation network; temporal and spatial patterns; city hierarchy level
