Based on previous literatures and case study, this paper sums up the enterprise-level FDI export spillover mechanism, namely horizontal FDI export spillover and vertical FDI export spillover.
通过相关文献梳理和案例分析，本文归纳出了企业层面FDI出口溢出的两个机理，即水平出口溢出和垂直出口溢出。
The integration of the above two indicates that compared with horizontal direction FDI export spillover is more likely to happen in vertical direction.
接着，本文对上述两层机理进行了综合分析，并指出FDI出口溢出本质上更有可能发生在垂直方向上，而非水平方向上。
