产业链关联、数字化投入与制造业高质量发展

Industrial Chain Association,Digital Investment and High-quality Development of Manufacturing Industry

百年未有之大变局下全球产业链加速调整和重构,我国制造业面临新的挑战。基于WIOD数据库以及统计年鉴匹配出制造业分行业数据,结合当前制造业面临的国际国内新形势,深入探究产业链关联对制造业高质量发展的影响以及数字化投入对该影响的偏效应。研究发现:①产业链关联能有效促进制造业高质量发展,并且数字化投入对其有正向的调节作用。②对于国内外关联来源,国内产业链关联对制造业高质量发展作用为正,但国外产业链关联作用为负。③对于不同类型的关联国家,产业链在与发展中国家关联时对制造业高质量发展的促进作用显著,与发达国家关联时促进作用则不明显。④产业链关联对高技术水平行业的促进作用较为显著。

The adjustment and restructuring of the global industrial chain has accelerated under the unprecedented change,and China's manufacturing industry is facing new challenges.Based on WIOD database and statistical yearbook matching manufacturing industry data,combined with the current international and domestic situation of the manufacturing industry,the impact of industrial chain correlation on the high quality development of manufacturing industry and digital input on the impact of the partial effect was explored deeply.The results showed that:(1)Industrial chain correlation could effectively promote the high quality development of manufacturing industry,and digital input had a positive adjustment effect on it.(2)For domestic and foreign correlation sources,domestic industry chain correlation had a positive effect on the high-quality development of manufacturing industry,but foreign industry chain correlation a negative effect.(3)For different types of related countries,the industrial chain had a significant promoting effect on the high-quality development of manufacturing industry when it was associated with developing countries,but not with developed countries.(4)Industrial chain correlation played a significant role in promoting high-tech industries.
