关于国家间生产力趋同的大量文献研究了生产力是否被拉向全球前沿国家，这可能是由于学习和知识溢出。最近，国内研究利用各公司生产率的广泛差异来探讨向国家边界的趋同。鉴于这种国内差异，国家之间的差异很难解释，因为很可能落后的平均国家中最好的公司至少高于领先的平均国家中的一些公司。因此，本文使用了许多国家的微观数据集，以更好地衡量全球和国家边界以及企业与边界的距离。使用英国的数据，我们发现，（a）国家前沿施加更强的拉国内企业比全球前沿和（B）拉从全球前沿福尔斯与技术距离下降，而拉从国家前沿没有。这一结果表明，企业可能在技术上远远落后，无法从全球前沿学习，但它们仍然能够从国内知识中受益。
An extensive literature on the convergence of productivity between countries examines whether productivity is pulled towards the global frontier country, perhaps due to learning and knowledge spillovers. More recently, studies within countries use the wide dispersion of productivity across firms to explore convergence to the national frontier. Given this within-country dispersion however between country-dispersion is hard to interpret, for it is quite possible that the best firms in a laggard average country are above at least some firms in a leading average country. This paper therefore uses micro data sets across many countries to build better measures of global and national frontiers and firms’ distance from them. Using UK data, we then find that (a) the national frontier exerts a stronger pull on domestic firms than does the global frontier and (b) the pull from the global frontier falls with technological distance, while the pull from the national frontier does not. This result suggests that firms might lag so far technologically that they cannot learn from the global frontier, while they still are able to benefit from domestic knowledge.
