Spatio-Temporal Differentiation of Regional Innovation Chain: Evidence From Beijing-Tianjin-Hebei Region.

Based on the provincial statistical data of the Beijing-Tianjin-Hebei region this paper uses the health distance model and obstacle degree model to explore the spatiotemporal mismatch of the development of the Beijing-Tianjin-Hebei regional innovation chain and analyzes the obstacle factor affecting the healthy development of Beijing-Tianjin-Hebei innovation chain. The results show that: (1) In terms of timing characteristics, the overall mismatch of the innovation chain in the Beijing-Tianjin-Hebei region shows a downward trend, and the absolute and relative difference of regional mismatch both show a "V" shaped development trend, which first decreases and then increases. (2) In terms of spatial characteristics, the mismatch of the innovation chain in the Beijing-Tianjin-Hebei region develops from unbalanced to balanced and then unbalanced, and the spatial pattern evolves from low in the middle and high around to high in the southeast and low around. (3) In terms of the obstacle factors, scientific research and development institutions, the number of college students, and the number of innovation platforms at or above the provincial and ministerial level are the obstacle factors to the more frequent occurrence. Plain Language Summary: preface This study aims to examine the spatio-temporal differentiation of the regional innovation chain in the Beijing-Tianjin-Hebei region of China. It investigates the mismatch between different components of the innovation chain and analyzes the factors that hinder its healthy development. The research utilizes the entropy method, health distance model, and obstacle degree model to calculate and analyze the innovation chain mismatch. Arc GIS geometric method is employed to divide the mismatch into different levels. Data from 2015 to 2019 is used to assess the evolution of the innovation chain mismatch over time and across different regions. The study reveals that the innovation chain mismatch in the Beijing-Tianjin-Hebei region has shown a declining trend during the study period. The overall mismatch has weakened, indicating significant progress in the coordinated development of the region. Beijing has played a leading role, while Tianjin and Hebei Province have also witnessed improvements, although to a lesser extent. The development difference among the three regions has been reduced, but significant disparities still exist. The findings highlight the importance of regional collaboration in promoting innovation chain development. The study provides insights for policymakers and stakeholders to enhance the coordination and integration of innovation activities in the Beijing-Tianjin-Hebei region. It emphasizes the need for further efforts to reduce development disparities and enhance the efficiency of innovation development. It is important to note that this study focuses specifically on the Beijing-Tianjin-Hebei region, and the findings may not be directly applicable to other regions or countries. The analysis is based on available data and selected models, which may have certain limitations and assumptions. Further research is needed to explore additional factors and dynamics influencing the innovation chain in the region. [ABSTRACT FROM AUTHOR]
