The diffusion of technological knowledge across regions is fundamental for enhancing innovation capacity and achieving balanced regional development. While prior research has highlighted the role of technological proximity in facilitating knowledge spillovers, it often neglects the dual nature of inter-city linkages that encompass both competition and complementarity. This paper extends the discussion by introducing the concept of technological complementarity, defined as cities sharing a broad cognitive base but specializing in different sub-fields, thereby creating heterogeneous yet synergistic technological structures. Using patent application and citation data from 284 Chinese cities between 2003 and 2019, we construct a novel index of inter-city technological complementarities based on IPC categories and link it with patent citation flows. The resulting panel of 681,748 city-pair observations enables a systematic empirical assessment of how complementarities shape technological knowledge diffusion.
The empirical results show that technological complementarities significantly promote inter-city technological knowledge diffusion. Cities with higher complementarities are more likely to cite each other’s patents, indicating stronger knowledge flows. A one-unit increase in complementarity is associated with a substantial rise in both the intensity and probability of patent citation. Unlike excessive similarity, which often induces homogeneous competition and technological lock-in, complementarities provide non-redundant knowledge resources, enhancing opportunities for recombination and innovation. Thus, complementarities are revealed as a critical driver of regional knowledge dynamics, contributing to the resilience and efficiency of innovation networks.
Mechanism analyses further reveal that complementarities foster knowledge diffusion through three pathways: collaborative innovation, technology transfer, and talent mobility. Complementary cities are more likely to engage in joint R&D and co-patenting, lowering communication barriers and facilitating tacit knowledge exchange. They also promote technology transfer, which transforms potential externalities into tradable innovation elements and strengthens cross-regional application of knowledge. In addition, complementarities stimulate the mobility of skilled talent, who act as carriers of tacit knowledge and bridge otherwise disconnected networks. These mechanisms collectively establish a robust chain through which complementarities translate into knowledge diffusion.
Finally, contextual and heterogeneity analyses show that the impact of complementarities is contingent on environmental conditions. Cultural distance increases communication costs and reduces complementarities’ effectiveness, whereas institutional proximity enhances cooperation predictability and amplifies diffusion. Transportation connectivity, particularly high-speed rail, mitigates spatial decay and enables complementarities to function over long distances. Moreover, eastern and high-tier cities benefit more strongly from complementarities due to superior absorptive capacity and institutional support, while effects are weaker in central, western, and lower-tier cities.
Overall, this study contributes to innovation geography and regional innovation empirically validating the role of technological complementarities in shaping inter-city knowledge diffusion, extending the theoretical framework beyond technological proximity, and providing policy implications for fostering collaborative innovation platforms, reducing institutional frictions, and facilitating talent and technology flows across regions.

在推动区域协调发展和创新驱动发展战略的背景下,技术知识在城市间的有效扩散成为提升区域协同创新能力与优化国家创新体系布局的关键。文章从城市间技术互补的视角出发,采用2003-2019年全国284个城市形成的40186个城市对所构造的面板数据,实证检验了城市间技术互补对城际技术知识扩散的影响及作用机制。研究发现,城市间技术互补显著促进城际技术知识扩散;技术互补能够通过推动城际协同创新、技术转移和创新人才流动进而促进城际技术知识扩散;随着文化距离和地理距离的增加,技术互补对城际技术知识流动的促进作用减弱,而随着制度邻近性和交通邻近性的提升,技术互补对城际技术知识流动的促进效应逐渐增强,同时交通邻近可以缓解地理距离带来的空间衰减效应;在区域资源禀赋和经济发展水平较高的城市之间,技术互补对城际技术知识扩散的促进作用更加明显。研究结论为推动区域协调发展进程中加强城际技术互补联系、优化区域创新资源配置、加强跨区域技术协同与提升国家创新体系整体效能提供了经验证据和政策启示。

Management Science,

70(11): 7464-7485., articleTitle=Proximity and knowledge spillovers: Evidence from the introduction of new airline routes, refAbstract=This paper examines the causal relationship between proximity and knowledge diffusion by estimating the elasticity of core-based statistical area (CBSA) pair-level citations to variations in travel time induced by the introduction of new flight routes. The findings reveal that decreasing travel time between U.S. cities by 20% increases knowledge flow by 0.5%, which corresponds to an increase of over 15,000 citations at the aggregate level. Rather than boosting within-firm knowledge transfer, travel time reduction leads to a rise in knowledge spillovers primarily across firm boundaries, particularly among those that form joint ventures, have block holdings in each other, or form supply chain relationships. These effects are stronger among city pairs located farther away from each other, with higher absorptive capacity, in complex technology classes, and for newly developed technologies. Additional mechanism tests suggest that the most likely channel through which travel time reduction impacts knowledge spillover is by influencing the transfer of tacit knowledge via facilitating cross-CBSA inventor flow and information acquisition.), Reference(id=1318316555184747282, tenantId=1146029695717560320, journalId=1308397381743640680, articleId=1318316546775167669, doi=10.2307/2118401, pmid=null, pmcid=null, year=1993, volume=108, issue=3, pageStart=577, pageEnd=598, url=https://academic.oup.com/qje/article-lookup/doi/10.2307/2118401, language=null, rfNumber=[29], rfOrder=36, authorNames=Jaffe A B, Trajtenberg M, Henderson R, journalName=The Quarterly Journal of Economics, refType=null, unstructuredReference=
