Integrating　complex　network　theory,　link　prediction　theory,　and　related　research　on　industrial　competition　relationship,　this　paper　proposes　the　theoretically　analytical　framework　of　the　competitive　relationship　among　Z-Park　high-tech　enterprises.　By　constructing　a　link　prediction　model,　we　reveal　the　internal　dynamics　that　affect　the　evolution　of　the　competitive　network　of　enterprises,　seek　the　best　index　reflecting　the　network　formation　mechanism,　and　apply　it　to　the　prediction　of　potential　competitive　associations.　©　2023,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG.
