Productivity effects of internationalisation through the domestic supply chain
研究了国内上游和下游行业进口或出口中间投入品对一家企业生产率的影响，发现国内获得也被出口的中间投入品会提高收入生产率，尤其对非外资企业和下游、低技术或劳动密集型行业更显著。
Summary This paper investigates productivity effects for a given firm resulting from the import or export of intermediate inputs by domestic upstream and downstream industries. With the use of manufacturing firms in 19 EU countries over the period 2000–2014, we find that domestic access to intermediate inputs that are also exported leads to higher levels of revenue productivity. The effect appears as more prominent for firms with nonforeign ownership and in relatively downstream, low‐tech or labour‐intensive industries. Subsequent exploration of mechanisms uncovers patterns consistent with learning by exporting on the part of upstream supplying industries that generates positive productivity spillovers to downstream firms.
