摘　　要：文章基于2007年、2012年、2017年国别及国内省际投入产出数据,运用多个统计指标,多视角对中国数字产业发展及制造业数字化密度的时空演化、区域和行业差异与收敛状况进行分析。研究发现:中国数字产业总体规模已超美国,内部结构向“软硬并重”转变,但对国民经济的影响仍存在“软硬失衡”现象;中国制造业数字化密度总体上有所提升,投入上的“重硬轻软”问题仍然存在;省际制造业数字化密度具有显著的空间和行业集聚性与异质性,空间上东部居前,西北落后,中部快速追赶,行业上技术密集型行业领先且省际差异小,劳动密集型和大部分资本密集型行业落后且省际差异显著。文章有助于全面厘清我国制造业数字化密度的总体及时空演化趋势,为解决我国制造业的内部数字化结构,以及地区、行业间数字化发展不平衡问题提供现实依据。Based on the national and provincial input-output data of 2007,2012 and 2017,this paper analyzes the spatio-temporal evolution,regional and industrial differences and convergence of China’s digital industry and its manufacturing industries’ digitalization density from multiple perspectives using various statistical indicators. It is found that the overall scale of China’s digital industry has surpassed that of the United States,and its internal structure tends to be more balanced between digital manufacturing industry and digital service industry,whose influence on the national economy are still imbalanced. The digitalization density of China’s manufacturing industry has increased in the whole,but the investment in digital manufacturing industry is much larger than in digital service industry. The digitalization density of manufacturing industry has significant spatial and industrial agglomeration and heterogeneity. Spatially,the East ranks first,the Northwest lags behind,and the Middle catches up quickly. In the view of industry,tech-intensive industries lead with little inter-provincial difference,while labor-intensive and most of the capital-intensive industries are backward with significant inter-provincial difference. This study helps to comprehensively clarify the overall and the spatio-temporal evolution of the digitalization density of China’s manufacturing industry,and provides a practical basis for improving the internal digitalization structure of China’s manufacturing industry and solving the developmental imbalance of digitalization among different regions and industries.
