【摘要】 创新链与产业链的无缝对接对于京津冀地区一体化发展至关重要，然而，北京对天津和河北的创新辐射效应并未充分释放，导致众多创新成果流向其他发达地区进行产业转化。本文聚焦京津冀战略性新兴产业，基于区位熵和耦合协调度模型，量化评估了2010—2022年京津冀一体化进程中创新链与产业链跨区域跨链协同水平的时空演化特征，同时剖析了协同水平差异背后的潜在原因。研究发现，河北省跨区域跨链协同水平不仅明显落后于京津两地，与长三角等发达区域相比也存在较大差距。尽管2014年京津冀协同发展战略实施后，河北省协同水平有所提升，但2021年后却呈现回落态势。究其原因，河北省新一代信息技术、数字创意产业和相关服务业的产业链发展长期滞后于北京的创新供给能力，这导致两地协同水平存在较大差距。同时，河北省在新能源、节能环保等先进制造领域产业链实现追赶与超越，但北京创新链的结构调整未能与河北产业链形成有效衔接，导致协同水平出现先升后降这一现象。最后，本文通过计量模型分析发现，要推动京津冀产业链发展，一方面要提高京津冀创新链与产业链的跨区域协同水平，另一方面需要政策协同和产业协同的共同发力。更多还原

【Abstract】 The seamless integration of the innovation chain and industrial chain is crucial for the integrated development of the Beijing-Tianjin-Hebei region. However, the innovation spillover effect of Beijing on Tianjin and Hebei has not been fully realized, resulting in a significant number of innovative achievements flowing to other developed regions for industrial transformation. This paper focuses on the strategic emerging industries in the Beijing-Tianjin-Hebei region and employs the location entropy and coupling coordination model to quantify the spatiotemporal evolution characteristics of cross-regional and cross-chain coordination levels between the innovation chain and industrial chain during the integration process from 2010 to 2022. The potential reasons behind the differences in coordination levels are also analyzed. The study reveals that Hebei’s cross-regional and cross-chain coordination level lags significantly behind that of Beijing and Tianjin and is also evidently inferior to more developed regions such as the Yangtze River Delta. Although Hebei’s coordination level improved after the implementation of the Beijing-Tianjin-Hebei Coordination Development Strategy in 2014,it declined after 2021. The reasons for this trend are that Hebei’s industrial chain development in new-generation information technology, digital creative industries, and related service sectors has long been behind Beijing’s innovation supply capacity, which is an important cause of the gap in coordination levels. Meanwhile, Hebei has achieved catch-up and even surpassed in advanced manufacturing fields such as new energy and energy-saving and environmental protection industries. However, the structural adjustment of Beijing’s innovation chain has failed to effectively connect with Hebei’s industrial chain, leading to the observed rise and subsequent decline in coordination levels. Finally, through the analysis of econometric models, this paper finds that to promote the development of the industrial chain in the Beijing-Tianjin-Hebei region, it is necessary not only to enhance the cross-regional collaborative level between the innovation chain and the industrial chain but also to ensure the joint efforts of policy coordination and industrial coordination.更多还原
