Abstract

Undoubtedly, digitalization makes the high-speed train industry more intelligent. Nevertheless, the impact of digital technology adoption on the green innovation quality, and subsequent green total factor productivity (GTFP) of Chinese high-speed train industry remains to be explored. Furthermore, how heterogeneous CEO social capital affects the effectiveness of digital technology adoption is also unresolved. Based on the fixed-effect estimation models and data of listed companies in Chinese high-speed train industry from 2009 to 2023, this study clarifies the relationship between digital technology adoption, green innovation quality, and GTFP, and verifies the moderating role of CEO business, political, and academic social capital. Empirical results indicate that digital technology adoption is positively correlated with the GTFP of Chinese high-speed train industry, and green innovation quality mediates the above relationship. Besides, CEO business and academic social capital would significantly strengthen the positive impact of digital technology adoption, while CEO political social capital does not. In addition, results of heterogeneity test indicate that digital technology adoption significantly nurtures the GTFP of enterprises in the eastern region and those with weak innovation capability, but has no significant impact on that of enterprises in the central and western regions and those with strong innovation capability.

中国高铁行业数字技术采用、绿色创新质量与绿色生产率：异质性CEO社会资本的作用

毫无疑问，数字化使高铁行业更加智能化。然而，采用数字技术对中国高铁产业绿色创新质量及后续绿色全要素生产率（GTFP）的影响仍有待探讨。此外，异质性CEO社会资本如何影响数字技术采用的有效性也未得到解决。本文基于固定效应估计模型和2009 - 2023年中国高铁行业上市公司数据，明确了数字技术采用、绿色创新质量与GTFP之间的关系，并验证了CEO商业资本、政治资本和学术社会资本的调节作用。实证结果表明，数字技术采用与中国高铁产业GTFP正相关，绿色创新质量在二者之间起中介作用。此外，CEO的商业和学术社会资本会显著增强数字技术采用的积极影响，而CEO的政治社会资本则不会。此外，异质性检验结果表明，采用数字技术显著培育了东部地区和创新能力较弱的企业的GTFP，而对中西部地区和创新能力较强的企业的GTFP没有显著影响。

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
