最近关于外来投资对国内企业生产率的行业内影响的实证研究发现,相当有力的证据表明没有(甚至是负面)影响。我们认为,在其他原因中,规范错误可能解释了其中一些结果。提出了一种更一般的规范,其中包含了通常的规范作为特例。使用1992-2000年意大利制造企业的数据,我们只有在考虑到更灵活的规范时才会发现正外部性。
Recent empirical works on the within-sector impact of inward investments on domestic firms’ productivity have found rather robust evidence of no (or even negative) effects. We suggest that, among other reasons, a specification error might explain some of these results. A more general specification, which includes the usual one as a special case, is proposed. Using data on Italian manufacturing firms in 1992–2000, we find positive externalities only once we allow for the more flexible specification.
