Analysis of China's Provincial Economic Link Network Based on PageRank Algorithm

Under the new dual-circulation development paradigm, traditional regional economic evaluation systems struggle to capture dynamic interactions between provinces. This study integrates complex network theory into regional economic research by constructing an inter-provincial economic network encompassing trade, investment, and population dimensions. Using the PageRank algorithm to assess node importance, the results reveal that the Yangtze River Delta dominates the trade network, while the investment network exhibits cross-regional characteristics driven by policy initiatives. In the population network, Ningxia and Qinghai serve as pivotal hubs. Between 2012 and 2023, the economic network evolved from a single-core structure in eastern regions to a multi-polar collaborative development model, with Jiangsu and Zhejiang provinces becoming primary cores. Meanwhile, central and western regions have shown gradual improvement. This research demonstrates enhanced regional resource allocation efficiency, providing insights for coordinated development processes while addressing previous limitations in dynamic mechanism analysis.
