装备制造业全球价值链融入程度与技术进步效应研究

The Effect of Equipment Manufacturing Industry Integration into Global Value Chain on Technological Progress

构建融入全球价值链(GVC)与技术进步效应的分析框架并提出研究假设,利用1999-2015年中国装备制造业7个细分行业面板数据,测算装备制造业融入GVC的程度指数和全要素生产率。结果显示,融入GVC程度指数整体呈现"W"型特征,2015年相比1999年呈上升趋势,各细分行业技术进步较为明显。实证结果表明:融入GVC对全要素生产率提升具有促进作用,但同时由于阻碍效应的存在,导致融入GVC与全要素生产率两者间呈现U型曲线关系。这是对融入GVC能够促进技术进步相关观点的重新认识。另外,产权制度因素、高素质科研人员规模能够显著促进技术进步;研发投入强度、出口密集度、条件建设强度在一定程度上阻碍了技术进步,但不显著。研究结论对于中国装备制造业通过融入GVC提高全要素生产率、实现技术进步具有重要政策启示。

This paper constructs the analysis framework and hypothesis on integration into the GVC and the effect of technological progress,using the panel data of 1999 to 2015 equipment manufacturing industry,calculates the integration index of equipment manufacturing industry based on input-output table,calculates total factor productivity using Solow residual method and data envelopment analysis.The result show that the equipment manufacturing industry integration into the GVC overall showing"W"type characteristics,compared with 2015 showed an upward trend in 1999;in addition,the technological progress of equipment manufacturing industry is more obvious.Empirical results show that integration into GVC can promote technological progress,but due to the existence of the"blocking effect",there is a"U"curve relationship between integration and technological progress.Besides,the factors for property right and the scale of high quality scientific research personnel have system-improved effect on technical progress.R&D、export intensity、construction intensity of fixed assets restricts technological progress in some extent.The conclusions of this paper have important policy implications for China's equipment manufacturing industry to improve total factor productivity and achieve technological progress.
