Could spillovers from multinationals affect the trade activities of local firms?
研究跨国公司对本地企业贸易活动的影响，发现同区域外资增加会挤出本地企业的进出口产品种类和来源地数量，但供应链联系有助于本地企业多元化，研发投入能缓解负面效应并增强正向溢出。
This paper examines spillovers from foreign affiliates of multinationals on various margins of trade of local firms. We find that a larger foreign presence in the same region crowds out the trade activity of local firms, resulting in a reduction of the number of products imported and exported, as well as of the number of origins where imports are sourced from. Supply chain linkages with foreign affiliates are instead found to help local firms to diversify their exports and imports. Engagement in R&D activity allows local firms to mitigate some of the negative effects of the presence of foreign-owned firms in the same region, and enhances the local firms’ gains arising through forward linkages.
