Exploring the Relationship Between Hub Nodes in an Urban Innovation Network:Innovation Dynamics in Guangzhou and Shenzhen's Biopharmaceutical Industry
Establishing an international center for science and technology innovation is one of the development goals for the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). As the two core cities within the area,Guangzhou and Shenzhen serve as pivotal nodes in its innovation network. This study constructs a network based on the innovation connections in the biopharmaceutical industry in the GBA from 2007 to 2021,analyzing the rela-tionships between Guangzhou and Shenzhen as core cities against the backdrop of the region's overall innovation network characteristics. The research reveals that:(1) The innovation network in the GBA,centered on biopharma-ceutical innovation,exhibits increasing density. The dual-core status of Guangzhou and Shenzhen is becoming more pronounced,with the pace of innovation cooperation between these two cities exceeding that of their collab-orations with surrounding cities,although their influence on the surrounding cities varies. (2) The micro-level in-novation network between Guangzhou and Shenzhen exhibits a multi-centric structure,with the network's evolu-tion trending toward complexity and multi-dimensionality. (3) Within this dual-core innovation relationship,the enthusiasm for initiating collaborative innovations differs among the micro-entities involved. The research indi-cates that advancing the construction of inter-city innovation networks and thus fostering a favorable"rainforest ecosystem"for innovation growth is an essential support for cultivating and developing innovation consortiums.
