中文摘要:
      中间品进口可以通过利用他国优质资源和技术溢出效应强化自身的资源和技术优势,进而促进本国出口产品质量和全球价值链分工地位的提升。一国在全球中间品进口网络中的网络特征(网络集约性和网络广延性)会影响其全球价值链分工地位,区域经济一体化带来的全球中间品进口网络非均质化使一国的区域中间品进口网络特征也会对其全球价值链分工地位产生显著影响。以2007—2017年“一带一路”沿线41个国家为研究样本,构建区域中间品进口网络矩阵并进行社会网络分析,结果表明:样本国家的全球价值链分工地位整体上趋于上升,且各国间的差距趋于缩小,与此同时,区域中间品进口网络的联系和密度增强,各国的网络集约性和网络广延性总体上也趋于提高;样本国家区域中间品进口网络集约性和广延性的提高均能显著促进其全球价值链分工地位的提升,其中技术进步具有调节效应,进口国技术水平的提高会强化其区域中间品进口网络特征对全球价值链分工地位的影响;样本国家区域中间品进口网络集约性和广延性提高对其全球价值链分工地位提升的促进效应具有时空异质性,该效应在“一带一路”倡议提出后比“一带一路”倡议提出前更强,在“一路”沿线国家比“一带”沿线国家更显著。因此,应继续深入推进“一带一路”建设,吸引更多经济体积极参与,并通过整体网络的优化升级和个体网络特征的改善来促进沿线各国全球价值链分工地位提升;同时,要进一步优化中间品贸易的产品结构和空间布局,并加快整体技术进步,以强化和提升中间品进口的技术溢出效应,进而有效提高出口产品质量和全球价值链分工地位。
英文摘要:
      The import of intermediate goods can strengthen its own resources and technological advantages by using the high-quality resources and technology spillover effects of other countries, thereby promoting the quality of domestic export products and the status of the division of labor in the global value chain. The network characteristics (network intensification and network extension) of a country in the global intermediate goods import network will affect its position in the division of labor in the global value chain. The heterogeneity of the global intermediate import network brought about by regional economic integration makes the characteristics of a country’s regional intermediate import network have a significant impact on its position in the global value chain division of labor. Taking 41 countries along the Belt and Road from 2007 to 2017 as research samples, the network matrix of regional intermediate goods imports is constructed and the social network analysis is conducted. The results show that the global value chain division status of sample countries tends to rise on the whole, and the gap between countries tends to narrow. Besides, the connection and density of the regional import network of intermediate goods have been increased, and the network intensification and network extension of all countries also tend to increase in general. The improvement of the intensification and extension of the regional intermediate product import network of sample countries can significantly promote the improvement of their position in the global value chain division of labor. Technological progress has a moderating effect, and the improvement of the technological level of the importing countries will strengthen the influence of the characteristics of the import network of intermediate goods on the division of labor in the global value chain. The promotion effect of the intensification and extensibility of the import network of intermediate goods in the sample countries on the improvement of their global value chain division of labor is spatiotemporal heterogeneity. This effect is stronger after the Belt and Road Initiative is proposed than before, and more significant in countries along “the Road” than in countries along “the Belt”. Therefore, it is necessary to continue to further promote the construction of the “Belt and Road”, attract more economies to actively participate in, and promote the improvement of the division of labor in the global value chain of countries along the route through the optimization and upgrading of the overall network and the improvement of individual network characteristics. Meanwhile, it is necessary to further optimize the product structure and spatial distribution of intermediate goods trade, and accelerate the overall technological progress to strengthen and enhance the technological spillover effect of intermediate goods imports, thereby effectively improving the quality of export products and the division of labor in the global value chain.
