摘　　要：基于世界投入产出数据库,本文检验了投入数字化对制造业出口国内增加值的影响。研究结果显示,通过生产率提升效应、中间品转换效应和高级要素虹吸效应,投入数字化可以显著提高制造业出口国内增加值。进一步研究发现,从数字投入类型看,数字硬件而非数字软件可以显著提高制造业出口国内增加值;从数字投入来源看,来源于境内而非境外的数字要素投入可以促进制造业出口国内增加值增长。分行业检验表明,投入数字化对技术密集型制造业出口国内增加值的提升作用最明显。本文研究结论对利用投入数字化提升中国制造业出口贸易利得,实现制造业出口高质量发展具有一定的启示。Based on the World Input and Output Database,this paper examined the impact of input digitalization on the domestic value added in export of manufacturing industry.The results show that input digitalization can significantly increase the domestic value added in export of manufacturing industry through productivity improvement effect,intermediate products conversion effect and advanced factor siphon effect.Further research finds that,from the perspective of the types of digital inputs,digital hardware rather than digital software can significantly increase the domestic value added in export of manufacturing industry.From the perspective of the sources of digital inputs,domestic rather than foreign digital inputs can promote the growth of domestic value added in export of manufacturing.In terms of different sectors,the results show that input digitalization has the most obvious effect on the increase of domestic value added in export of technology-intensive manufacturing.The conclusions of this paper provide significant implications for utilizing input digitalization to improve the gains from export of China's manufacturing industry and achieve high-quality development for manufacturing'export.
