摘要
文章基于制造业服务化与制造业生产率之间的互动关系,利用我国27个地区以及16个制造业分行业的地区投入产出表与中国工业统计年鉴的合并数据,从行业和区域双视角检验制造业服务化对我国制造业生产率的影响效果。研究结果发现:制造业服务化对我国制造业生产率的提升有显著的促进效应,且兼具行业异质性和区域异质性;其中,低技术密集型制造业服务化所引致的制造业生产率提升效应明显高于高技术密集型制造业;不同地区的制造业服务化水平对其生产率的影响亦有阶段性的差异,分别呈现出“马鞍型”“U”型和倒“U”型三种趋势。
Based on the interactive relationship between the manufacturing industry servicizing and manufacturing productivity, this paper uses the merging data of the regional input-output table of 27 regions and 16 manufacturing sub-sectors in China and the China Industrial Statistical Yearbook to test the impact effect of the manufacturing industry servicizing on China’s manufacturing productivity from dual perspectives of industry and regions. The results of the study show that the manufacturing industry servicizing has a significant effect on the improvement of China’s manufacturing productivity with the industry and the regional heterogeneity;the improvement effect of the low-tech-intensive manufacturing industry made by the manufacturing industry servicizing is significantly higher than that of the high-tech-intensive manufacturing;the impact of the manufacturing industry servicizing level in different regions on their productivity also varies periodically, showing a “saddle shape”, a “U shape” and an “inverted U shape” respectively.
