进口价值链质量促进了国内价值链质量提升吗?

Does Import Value Chain Quality Promote Domestic Value Chain Quality?

在中国经济向高质量发展转变的形势下,研究全球价值链和国内价值链质量具有积极的现实意义。文章提出了价值链质量概念和测算方法,综合考虑了价值链条上中间产品的质量与参与企业间的生产关联关系。在将全球价值链拆分为国内价值链和进口价值链的基础上,文章提出了全球价值链、国内价值链和进口价值链质量的概念并进行了数据测算。实证分析结果显示,进口价值链质量对国内价值链质量提升具有积极的促进作用,虽然金融危机以来这种促进作用有所削弱。中国应重视和积极培育国内价值链成长,充分利用进口价值链产生的技术外溢,提升国内经济一体化水平。

Under the situation that China’s economy is changing to high-quality development,it is of practical significance to study the quality of global value chain and domestic value chain. The paper puts forward the concept and calculation method of value chain quality,and comprehensively considers the quality of intermediate products in the value chain and the production relationship between participating enterprises. On the basis of splitting the global value chain into domestic value chain and import value chain,this paper puts forward the concept of quality of global value chain,domestic value chain and import value chain and carries out data calculation. Empirical analysis shows that the quality of import value chain has a positive role in promoting the quality of domestic value chain,although this role has been weakened since the financial crisis. China should attach importance to and actively cultivate the growth of domestic value chain,make full use of the technological spillovers generated by the import value chain,and enhance the level of domestic economic integration.
