Abstract

The differentiated frequencies of high-speed rail (HSR) services among cities have emerged as a critical factor in reshaping patterns of intercity collaborative innovation. Using panel data of Chinese city pairs from 2008 to 2019, this study develops two original datasets: one capturing intercity HSR frequency and the other documenting joint patent applications. These datasets are used to examine how variations in HSR frequency influence the structure and intensity of intercity collaborative innovation networks. The key findings are as follows: (1) Cities with higher HSR frequencies exhibit significantly greater levels of collaborative innovation with other cities; (2) A comparative analysis of HSR hub, sub-hub and peripheral cities reveals that hub and sub-hub cities possess notable advantages in fostering collaborative innovation relative to peripheral cities; (3) Heterogeneity analysis indicates that the impact of HSR frequency is more pronounced in cities with smaller populations and in those located closer to major central cities; and (4) The development of the HSR network has reshaped both the structural configuration and the spatial distribution of China's intercity collaborative innovation networks.

频率问题：中国高铁网络对城际协同创新网络的影响

城市间高铁服务的差异化频率已成为重塑城际协同创新模式的关键因素。利用2008 - 2019年中国城市对的面板数据，本研究开发了两个原始数据集：一个捕获城际高铁频率，另一个记录联合专利申请。这些数据集用于研究高铁频率的变化如何影响城际协同创新网络的结构和强度。研究发现：(1)高铁频次越高的城市与其他城市的协同创新水平显著越高；(2)高铁枢纽、子枢纽和周边城市的对比分析表明，枢纽和子枢纽城市在促进协同创新方面相对于周边城市具有显著优势；(3)异质性分析表明，人口规模较小的城市和距离主要中心城市较近的城市，高铁频次的影响更为显著；(4)高铁网络的发展重塑了中国城际协同创新网络的结构形态和空间分布。

期刊介绍： Research in Transportation Business & Management (RTBM) will publish research on international aspects of transport management such as business strategy, communication, sustainability, finance, human resource management, law, logistics, marketing, franchising, privatisation and commercialisation. Research in Transportation Business & Management welcomes proposals for themed volumes from scholars in management, in relation to all modes of transport. Issues should be cross-disciplinary for one mode or single-disciplinary for all modes. We are keen to receive proposals that combine and integrate theories and concepts that are taken from or can be traced to origins in different disciplines or lessons learned from different modes and approaches to the topic. By facilitating the development of interdisciplinary or intermodal concepts, theories and ideas, and by synthesizing these for the journal''s audience, we seek to contribute to both scholarly advancement of knowledge and the state of managerial practice. Potential volume themes include: -Sustainability and Transportation Management- Transport Management and the Reduction of Transport''s Carbon Footprint- Marketing Transport/Branding Transportation- Benchmarking, Performance Measurement and Best Practices in Transport Operations- Franchising, Concessions and Alternate Governance Mechanisms for Transport Organisations- Logistics and the Integration of Transportation into Freight Supply Chains- Risk Management (or Asset Management or Transportation Finance or ...): Lessons from Multiple Modes- Engaging the Stakeholder in Transportation Governance- Reliability in the Freight Sector
