摘　　要：本文在构建数字技术偏向与生产率增长的测算模型基础上,利用2002-2022年中国投入产出表中数据考察数字技术偏向下制造业行业生产率的收敛效应。研究结果表明:中国制造业数字化要素之间呈互补关系,且数字化要素替代弹性具有明显的行业差异性;制造业数字技术总体偏向数字化资本,但近些年偏向程度明显减弱;数字化资本偏向性技术行业的生产率增长明显高于数字化劳动偏向性技术行业。进一步研究表明,制造业行业总体上不存在σ收敛和β收敛,但数字化资本偏向性技术行业和数字化劳动偏向性技术行业存在β收敛,且前者的收敛速度快于后者;同时,数字化资本增长率和研发投入对制造业生产率增长具有显著的促进作用。因此,在制造强国战略推进中,制造业应充分利用各行业资源发展适宜数字技术,并利用智能化、网络化和数字化拓展各行业的合作领域,以合作促创新,走出一条互利共赢的生产率提升路径,实现制造业高质量发展。Based on the calculation model of digital technology bias and total factor productivity growth,this paper uses the data in China's input-output table from 2002 to 2022 to test the convergence effect of total factor productivity in manufacturing industry under digital technology bias.The results show that the digitalization factors in China's manufacturing industry are complementary,and the digitalization factor substitution elasticity has obvious industry differences;Digital technology in manufacturing industry is generally biased towards digital capital,but the degree of bias is obviously weakened in recent years.The total factor productivity growth of digital capital-biased technology industry is significantly higher than that of digital labor-biased technology industry.Further research shows that there is no σ convergence and β convergence in the manufacturing industry as a whole,but β convergence exists in the digital capital-biased technology industry and the digital labor-biased technology industry,and the convergence speed of the former is faster than the latter.At the same time,the growth rate of digital capital and R&D investment have a significant promoting effect on the growth of manufacturing total factor productivity.Therefore,in the promotion of the strategy of manufacturing power,the manufacturing industry should make full use of the resources of various industries to develop appropriate digital technologies,and use intelligence,networking and digitalization to expand the fields of cooperation in various industries,promote innovation through cooperation,and walk out of a mutually beneficial and win-win path of total factor productivity improvement to achieve high-quality development of the manufacturing industry.
