英文文献摘要：
This study assesses the mobile phone in the diffusion of knowledge for better governance in sub-Saharan Africa for the period 2000-2012. For this purpose we employ Generalised Method of Moments with forward orthogonal deviations. The empirical evidence is based on three complementary knowledge diffusion variables (innovation, internet penetration and educational quality) and ten governance indicators that are bundled and unbundled. The following are the main findings. First, there is an unconditional positive effect of mobile phone penetration on good governance. Second, the net effects on political, economic and institutional governances that are associated with the interaction of the mobile phone with knowledge diffusion variables are positive for the most part. Third, countries with low levels of governance are catching-up their counterparts with higher levels of governance. The above findings are broadly consistent with theoretical underpinnings on the relevance of mobile phones in mitigating bad governance in Africa. The evidence of some insignificant net effects and decreasing marginal impacts may be an indication that the mobile phone could also be employed to decrease government quality. Overall, this study has established net positive effects for the most part. Five rationales could elicit the positive net effects on good governance from the interaction between mobile phones and knowledge diffusion, among others, the knowledge variables enhance: reach, access, adoption, cost-effectiveness and interaction. In a nut shell, the positive net effects are apparent because the knowledge diffusion variables complement mobile phones in reducing information asymmetry and monopoly that create conducive conditions for bad governance. The contribution of the findings to existing theories and justifications of the underlying positive net effects are discussed.
本研究评估了2000-2012年期间移动电话在撒哈拉以南非洲为改善治理而传播知识的情况。为此，我们采用正正交偏差矩的一般方法。经验证据基于三个互补的知识扩散变量(创新、互联网普及率和教育质量)和十个捆绑和非捆绑的治理指标。以下是主要发现。首先，手机普及对良治具有无条件的积极作用。第二，手机与知识扩散变量之间的交互作用对政治、经济和制度治理的净影响大部分为正的。第三，治理水平低的国家正在追赶治理水平高的国家。上述发现与手机在缓解非洲不良治理方面的相关性的理论基础基本一致。一些不显著的净影响和减少的边际影响的证据可能表明，移动电话也可以用于降低政府质量。总的来说，这项研究在很大程度上已经确定了净正面效应。手机与知识扩散之间的相互作用可产生对善治的积极净效应，其中，知识变量增强:reach、access、adoption、cost-effectiveness和interaction。在坚果壳中，积极的净效应是明显的，因为知识扩散变量补充了手机，减少了信息不对称和垄断，为不良治理创造了有利条件。研究结果对现有理论的贡献和潜在的积极净效应的理由进行了讨论。
