The　digital　economy　is　an　important　engine　for　building　a　modern　economic　system.　Corporate　investment　is　an　important　factor　driving　the　growth　of　the　digital　economy.　The　development　and　decision-making　of　the　digital　economy　industry　requires　an　urgent　insight　into　the　structural　characteristics　of　the　investment　and　financing　of　related　companies　and　their　temporal　and　spatial　evolution　patterns.　This　paper　takes　Fujian　Province,　the　ideological　source　and　practical　starting　point　of　＂Digital　China＂　as　a　research　case,　based　on　the　investment　and　financing　data　of　digital　economy　enterprises　from　2000　to　2021,　adopts　complex　network　analysis　and　negative　binomial　regression　model,　and　takes　prefecture-level　cities　as　the　basic　research　unit　to　explore　spatial　characteristics　and　influencing　factors　of　investment　and　financing　of　digital　economy　enterprises　in　Fujian　Province.　This　research　finds　that:　firstly,　the　investment　and　financing　scale　of　digital　economy　enterprises　in　Fujian　shows　an　increasing　trend,　and　the　source　of　investment　has　changed　from　non-digital　economy　enterprises　to　digital　economy　enterprises.　Secondly,　the　proportion　of　inter-provincial　of　investment　has　gradually　increased.　Inter-provincial　of　investment　increases　from　856　million　yuan　in　2000　to　28.808　billion　yuan　in　2021,　and　the　proportion　increases　from　11.59%　to　31.06%.　The　amount　of　financing　is　＂high　in　the　east　and　low　in　the　west＂.　Thirdly,　Fuzhou　has　always　been　the　preferred　city　for　corporate　investment,　but　with　the　passage　of　time,　Xiamen,　Quanzhou,　and　other　hubs　continue　to　emerge,　agglomerating　to　form　the　Fuzhou-Xiamen-Quan　Corridor　at　its　core.　Fourthly,　among　the　influencing　factors,　policies　and　the　development　environment　of　informatization　have　a　significant　role　in　promoting　the　investment　and　financing　connection　of　digital　economy　enterprises,　and　the　influence　of　geographical　distance　on　the　investment　and　financing　connection　of　digital　industry　is　gradually　weakened.　Finally,　combined　with　the　spatiotemporal　evolution　of　the　development　of　the　digital　industry　in　Fujian　and　its　influencing　factors,　the　paper　puts　forward　policy　suggestions,　in　order　to　provide　scientific　support　for　the　construction　of　＂Digital　Fujian＂　and　the　sustained　and　healthy　development　of　the　digital　economy　in　Fujian.　©　2023　Journal　of　Geo-Information　Science.　All　rights　reserved.
