The Spatial Evolution and Influencing Factors of Innovation Capital Flow in the Beijing-Tianjin-Hebei Region
Innovation has become the first driver for the high-quality development of China's economy.With the development of information and communication technology,resources can be realized in the form of flow across regions,and the flow space has become a new organizational form to promote the innovative development of urban agglomerations.The formation of innovation capital flow space in the Beijing-Tianjin-Hebei city cluster is conducive to breaking the communication barriers of innovation subjects in the city cluster,upgrading innovation factors and resource integration efficiency,and further strengthening the innovation synergy within the city cluster in the form of new space,thus facilitating further breakthrough of innovation capability.From the perspective of flow space,this paper analyzes the progress and effectiveness of innovation capital flow space in the Beijing-Tianjin-Hebei city clus-ter,sorting out the distribution pattern of innovation capital flow space and the role of the node network,which helps clarify the structure of the city system under the innovation capital flow space in the Beijing-Tianjin-Hebei city cluster and the status of innovation flow space in each city.It promotes the synergistic innovation of the Beijing-Tianjin-Hebei city cluster and has practical significance for promoting the high-quality development of the Beijing-Tianjin-Hebei city cluster.This paper employs capital mutual investment data of the science and technology service industry among 13 prefecture-level cities in the Beijing-Tianjin-Hebei city cluster to construct the network of innovation capital flow space of the Beijing-Tianjin-Hebei city cluster and analyzes it by using the gephi software,showing the basic char-acteristics and evolution trend of the innovation capital flow space of the Beijing-Tianjin-Hebei city cluster in 2012-2021.It is found that the"three-legged tripod"pattern in Beijing,Tianjin,and Hebei has been formed and the innovation links in the flow space are increasingly close;the accessibility of the innovation capital flow space in Beijing,Tianjin,and Hebei and the closeness of the linkage have increased significantly;the status of Beijing,Tianjin,and Shijiazhuang in the flow space has been promoted,and the development gap between the node cities has been reduced significantly;the independence of the node cities and their ability to control the resources in the innovation flow space have been strengthened.The proposed policy measures are as follows.Firstly,core cities should drive the peripheral cities to achieve more innovation interaction and optimize the spatial structure of the regional innovation flow.Secondly,the Beijing-Tianjin-Hebei regional innovation synergy should be promoted to establish a real-time coordinated and mutually sup-portive regional innovation flow space.Thirdly,the organic fusion of the industrial chain and the innovation chain should be actively promoted to make the industrial upgrading and the technological R&D mutual supply and de-mand.Fourthly,the strategic initiatives for promoting scientific and technological innovation should be adopted.
