At Shanghai University, a research team identifies 29 Chinese AI clusters using location quotients and social network analysis of patent data, then employs dynamic panel System-GMM to assess how industry policies influence technological innovation. They find policies significantly stimulate innovation but that clusters with high closeness centrality experience diminished policy impact. This suggests policymakers should balance cluster network structures when devising supportive measures for AI development.
Key points
Identified 29 AI clusters in China using location quotients and social network analysis on patent data.

AI Clusters and Their Impact on Longevity Research
Overview: Artificial intelligence (AI) clusters are geographic regions where AI enterprises, research institutions, and universities co-locate and collaborate intensively. These clusters accelerate the exchange of knowledge, resources, and talent, creating fertile environments for rapid innovation. In longevity science, AI clusters provide critical infrastructure for developing data-driven approaches, machine-learning models, and computational tools that advance our understanding of aging processes.
What Are AI Clusters?
AI clusters form when organizations working on AI technologies—such as deep learning, natural language processing, and computer vision—converge within a specific geographic area. This convergence yields benefits like:
- Knowledge Spillover: Frequent interactions among cluster members enable sharing of best practices, research findings, and technical insights.
- Specialized Labor Pool: A concentrated talent base of data scientists, engineers, and domain experts reduces hiring overhead and fosters collaboration.
- Shared Infrastructure: Access to high-performance computing facilities and collaborative labs lowers barriers for startups and research groups.
Mechanisms Driving Cluster Success
- Location Quotient (LQ) measures regional specialization in AI by comparing local patent output to national averages, highlighting agglomeration hotspots.
- Social Network Analysis (SNA) maps collaboration ties via joint patents, revealing interregional and intraregional connections that sustain innovation networks.
- Dynamic Panel Modeling (e.g., System-Generalized Method of Moments) assesses how policy inputs and network positions jointly influence patent outputs over time.
Relevance to Longevity Research
Longevity science aims to understand and extend healthy human lifespan through multidisciplinary approaches encompassing biology, medicine, and technology. AI clusters contribute by:
- Accelerating Drug Discovery: Machine-learning models trained on large datasets of genetic and molecular information can predict compounds that target aging pathways more efficiently.
- Analyzing Complex Data: AI algorithms process high-dimensional omics datasets (genomics, proteomics, metabolomics) to identify biomarkers of aging and age-related diseases.
- Modeling Biological Systems: Computational simulations of cellular networks and organ systems help researchers test longevity interventions in silico before clinical trials.
Policy and Network Considerations for Longevity Hubs
Governments and regional authorities can catalyze longevity research by investing in AI clusters that blend computational power with biomedical expertise. Key actions include:
- Targeted Funding: Subsidies for collaborative projects between AI developers and aging researchers ensure alignment of technological advances with longevity goals.
- Talent Programs: Fellowships and training initiatives that bridge AI and geroscience attract interdisciplinary experts.
- Infrastructure Sharing: Establishing shared data repositories and computing centers tailored to longevity datasets fosters open innovation.
By understanding the dynamics of AI clusters, stakeholders can design environments that amplify innovation in longevity science, paving the way for breakthroughs that extend healthy human life.
