VERTICAL INDUSTRY RELATIONS, SPILLOVERS, AND PRODUCTIVITY: EVIDENCE FROM CHILEAN PLANTS*
利用智利工厂数据和投入产出表，研究发现上游产业工厂对下游工厂的全要素生产率有显著正向溢出，但下游产业或无关产业无此效应。
ABSTRACT We use disaggregated data on Chilean plants, and the Chilean input–output table to examine the impact of agglomeration spillovers on total factor productivity (TFP). In common with previous studies, we find evidence for intraindustry spillovers, but none for general cross‐industry spillovers. This picture changes when we take vertical industry relations into account. There are important productivity spillovers from plants in upstream industries. Interestingly, a similar effect cannot be found from plants in downstream industries. The number of plants in these sectors has no effect on plant‐level TFP, just as the number of plants in other industries that are neither important upstream suppliers nor downstream customers also has no effect.
