Structural characteristics and proximity comparison of China's urban innovation cooperation network.

ABSTRACT: How to promote and improve the level of urban innovation cooperation is a major issue in China's current high-quality economic development. Thus, enhancing innovation ability is essential to achieving high-quality economic growth under the "new normal". Based on the data of Chinese invention patents from 1985 to 2017, this paper analyzes the characteristics of China's urban innovation cooperation network and the different roles of proximity by using social network analysis and exploratory spatial data analysis methods. The analysis results show that: (1) On the whole, the development of China's urban innovation cooperation network is characterized by stages (initial development stage, rapid development stage, and gradual decline stage); The urban innovation cooperation network has strong connectivity and centripetal concentration but its imbalance needs to be further improved; The degree of urban participation has gradually increased, consolidating the stability of the network structure. (2) The centrality of urban innovation cooperation network has obvious characteristics of administrative center orientation, coastal areas orientation, and 'strong east and weak west'; Beijing is the center and bridge of the network, and the network flattening characteristics are obvious; A hierarchical 'core-edge' structure is gradually formed for the urban innovation cooperation network, and the pyramid structure with Beijing standing at the top is being consolidated. (3) The geographical proximity presents a significant global spatial positive correlation, while the network proximity and pure network proximity have a more significant global spatial negative correlation; The local spatial autocorrelation of China's urban innovation cooperation system based on network proximity is more obvious and identifiable than that based on the geographical proximity, which better reflects the new development model of "relationship economy".

Project description:With the development of economic globalization, urban agglomerations have become growth poles and core areas of economic development. By building knowledge innovation networks in urban agglomerations, we can effectively improve the strength of inter-city knowledge innovation links and better realize the integrated and synergistic development of the region. This study selected core cities in the Yangtze River Delta urban agglomeration as the study area, constructed the knowledge innovation network based on inter-city dissertation cooperation data from 2010 to 2020, and analyzed the characteristics and evolution of its knowledge network by combining social network analysis and geospatial analysis. The research results show that: (1) with changes in policies and investment in scientific research and innovation, intra-regional thesis cooperation in the Yangtze River Delta urban agglomeration has been increasing and the scale of the knowledge innovation cooperation network is growing; (2) in addition to the core cities radiating innovation resources outward to drive the development of other node cities, other cities are continuously improving their own innovation capabilities, taking the initiative to strengthen knowledge innovation cooperation with core cities and enhancing their own position in the network; (3) there are no longer isolated cities within the Yangtze River Delta urban agglomeration, and a multi-core knowledge network structure centered on Shanghai, Nanjing, Hangzhou, and Suzhou has initially formed, but the network is still spatially heterogeneous; (4) there are still problems within the Yangtze River Delta urban agglomeration such as uneven development of knowledge innovation and low participation of peripheral cities, which need to be addressed jointly by all regions. The article concludes with some suggestions for countermeasures to provide a reference for the Yangtze River Delta urban agglomeration to continuously strengthen intra-regional knowledge cooperation in the future, enhance regional competitiveness, and ultimately achieve synergistic development among cities.

Project description:BackgroundThe "Double First-Class" refers to world first-class university and first-class academic discipline construction proposed by China government. The "Double First-Class" construction medical universities have made many clinical research achievements, but the analysis and evaluation of research collaboration networks in the field of clinical research are still lacking.MethodsClinical research papers by 23 "Double First-Class" construction medical universities in China from 2000 to 2019 indexed in the databases of the China National Knowledge Infrastructure and Web of Science (WoS) databases were collected. Through the social network analysis (SNA) method and Ucinet software, the interuniversity research cooperation networks of domestic and international publications were comparatively analyzed at the overall, individual, and group levels in terms of number of publications, cooperation network matrix, centrality analysis, cohesive subgroup analysis, and core-periphery structure to understand the developmental status of the cooperative network of clinical research publications among China's "Double First-Class" construction medical universities.ResultsThe cooperation among China's "Double First-Class" construction universities showed certain regional distribution characteristics, and they showed closer cooperation in publishing papers in international journals than in domestic ones. The overall density of the domestic-journal research collaboration network of the universities was 0.4229, mainly centered on Beijing University of Traditional Chinese Medicine and Shanghai University of Traditional Chinese Medicine. In contrast, the overall density of international-journal research collaboration network was 0.9052, mainly centered on Peking University, Central South University, and Zhengzhou University, with large differences in subgroup density and low integration.ConclusionsTo promote the development of clinical research, it is necessary to improve the construction of the interuniversity clinical research collaboration system, build a national clinical research network with a multilevel structure and sophisticated functions, and expand resource sharing as well as collaborative innovation capacity.
