【摘要】：制造业进口多样化程度上升会提高其生产率。首先利用UNCOMTRADE数据测算2001—2014年我国25个制造业细分行业的进口多样化程度,发现制造业总体进口多样化程度先下降后上升,呈现阶段性波动;不同要素密集度制造业的进口多样化程度存在差异,资本密集型制造业进口多样化程度最高、资源密集型制造业最低。其次提出制造业进口多样化可以通过横向竞争效应、横向学习效应和纵向溢出效应提高其生产率,集中表现为劳动生产率上升。最后采用系统GMM方法估计动态面板数据,证实我国制造业进口多样化程度上升的确存在提高劳动生产率的效应,但是这种效应在不同要素密集度制造业中存在差别,进口多样化程度上升显著促进资源密集型和劳动密集型制造业劳动生产率提高、对资本密集型制造业劳动生产率的影响不够显著。
[Abstract]:Increased diversification of manufacturing imports will increase its productivity. First, using UNCOMTRADE data to estimate the import diversification degree of 25 manufacturing sectors in China from 2001 to 2014, it is found that the total import diversification degree of manufacturing industry decreases first and then rises, showing periodic fluctuation. The degree of import diversification of different factor intensive manufacturing industry is different, the capital intensive manufacturing industry has the highest import diversification degree, and the resource intensive manufacturing industry has the lowest. Secondly, the paper points out that manufacturing import diversification can improve its productivity through horizontal competition effect, horizontal learning effect and vertical spillover effect, and focus on the increase of labor productivity. Finally, the dynamic panel data are estimated by the systematic GMM method, which proves that the increase in the degree of import diversification of manufacturing industry does have the effect of increasing labor productivity, but this effect is different in different factor intensity manufacturing industries. The increase of import diversification significantly promotes labor productivity of resource-intensive and labor-intensive manufacturing industries, but the impact on labor productivity of capital-intensive manufacturing industries is not significant.
