英文文献摘要：
The purpose of this study is to investigate whether enhancing financial access influences productivity in Sub-Saharan Africa. The research focuses on 25 countries in the region with data for the period 1980-2014. The adopted empirical strategy is the Generalised Method of Moments. The credit channel of financial access is considered and proxied by private domestic credit while four main total factor productivity (TFP) dynamics are adopted for the study, namely: TFP, real TFP, welfare TFP and real welfare TFP. It is apparent from the findings that enhancing financial access positively affects welfare TFP whereas the effect is not significant on TFP, real TFP and welfare TFP. Policy implications are discussed. The study complements the extant literature by engaging hitherto unemployed dynamics of TFP in Sub-Saharan Africa.

本研究的目的是调查提高金融准入是否会影响撒哈拉以南非洲地区的生产率。该研究以该地区25个国家为研究对象，收集了1980-2014年期间的数据。所采用的经验策略是矩的一般方法。金融准入的信贷渠道由国内私人信贷来考虑和代理，而全要素生产率(TFP)的四个主要动态为:TFP、真实TFP、福利TFP和真实福利TFP。研究结果显示，增加金融准入对福利全要素生产率有正向影响，但对全要素生产率、真实全要素生产率和福利全要素生产率的影响不显著。讨论了政策含义。这项研究通过研究撒哈拉以南非洲迄今为止全要素生产率的失业动态来补充现有的文献。
