[摘要：為研究數(shù)字經(jīng)濟(jì)對(duì)海洋經(jīng)濟(jì)高質(zhì)量發(fā)展的賦能效應(yīng)，文章選取2007—2022年沿海11個(gè)省份的面板數(shù)據(jù)，構(gòu)建海洋經(jīng)濟(jì)發(fā)展質(zhì)量和數(shù)字經(jīng)濟(jì)發(fā)展水平的指標(biāo)體系，計(jì)量數(shù)字經(jīng)濟(jì)對(duì)海洋經(jīng)濟(jì)高質(zhì)量發(fā)展的實(shí)際效應(yīng)，在此基礎(chǔ)上，運(yùn)用中介效應(yīng)模型和門檻效應(yīng)模型分析其理論機(jī)制與發(fā)展路徑。實(shí)證結(jié)果表明：數(shù)字經(jīng)濟(jì)對(duì)海洋經(jīng)濟(jì)高質(zhì)量發(fā)展存在顯著的促進(jìn)作用；數(shù)字經(jīng)濟(jì)通過人力資本積累效應(yīng)、產(chǎn)業(yè)結(jié)構(gòu)升級(jí)效應(yīng)和生產(chǎn)服務(wù)智能化效應(yīng)賦能海洋經(jīng)濟(jì)高質(zhì)量發(fā)展；數(shù)字經(jīng)濟(jì)對(duì)海洋經(jīng)濟(jì)高質(zhì)量發(fā)展存在顯著的門檻效應(yīng)。（剩余15978字）
