中国装备制造业服务化与绿色全要素生产率研究——基于新型国际分工下的GVC视角

Research on China’s Equipment Manufacturing Service and Green Total Factor Productivity (GTFP) from the Perspective of Global Value Chain

环境规制背景下,推动中国装备制造业转型升级的关键因素是提升其绿色全要素生产率。本文基于新型国际分工下的GVC视角,借鉴KPWW贸易增加值的理论框架,利用世界投入产出(WIOD)数据库及中国工业数据年鉴等多种数据来源,分析了中国装备制造业投入服务化水平、绿色全要素生产率及两者间的影响效应。研究发现:中国各装备制造业高端投入服务化率水平因技术密集度不同而具有明显差异;样本期间,中国装备制造业的绿色全要素生产率整体呈现不断改善状态,技术进步是其增长的主要驱动因素;GVC视角下中国装备制造业投入服务化促进了绿色全要素生产率提升,且基于服务投入异质性的分析显示,高端化服务投入对绿色全要素生产率的促进效应显著高于低端化服务投入。

Under the perspective of environmental regulation,increasing the GTFP is the crucial factor to restructure and upgrading China’s equipment manufacturing industry. From the perspective of GVC,based on the WIOD database,Chinese Industrial Statistics Yearbook and other multi database by applying KPWW-TiVA theoretical framework,this paper measures the servitization of China’s equipment manufacturing industry,and analyzes its impact on GTFP. The results show that firstly,the average servitization level of China’s equipment manufacturing industry is significantly different due to technology intensities discrepancy. Secondly,during the sample period,the overall GTFP of China’s equipment manufacturing industry has been improved continuously and the main drivers are technological progress. Thirdly,the servitization of equipment manufacturing industry has a positive impact on GTFP under the GVC background. Based on analysis of heterogeneity of servitization,it is found that the impact of high-end servitization on GTFP is greater than the low-end one.
