Using a sample of 309 Small and Medium-sized Enterprises (SMEs) from Tanzania and applying partial least square structural equation modeling, the study analyses the different effects of managers' general and specific human capital on SME innovation and productivity. The results demonstrate that top managers with higher education qualification place greater importance on non-technological innovation in comparison with their less educated peers. They further show that managers with more years of experience in the sector place higher importance on technological innovation than their less experienced counterparts. In addition, the results show that SMEs with managers who have higher education qualification achieve higher productivity than their less educated peers, with marketing innovation partially complementarily mediating this relationship. The effect of top managers' experience in the sector on SME productivity is shown to be insignificant. This paper uncovers the mediating role of marketing innovation on the relationship between top managers' human capital and SME productivity in Tanzania. Previous research did not consider the role of innovation as a means to translate top manager's human capital into firm productivity. These results help to provide some practical suggestions for managers, entrepreneurs and policy makers. This is a cross-sectional study which might not have captured all the effects of top managers' human capital fully.
本研究以坦桑尼亚的309家中小企业为样本，运用偏最小二乘结构方程模型，分析了管理者的一般人力资本和特定人力资本对中小企业创新与生产率的不同影响。结果表明，与受教育程度较低的同行相比，受过高等教育的高层管理者更重视非技术创新。结果还表明，在该行业拥有更多年经验的管理者比经验较少的同行更重视技术创新。此外，结果显示，管理者具有高等教育学历的中小企业比受教育程度较低的同行生产率更高，营销创新部分互补地调节了这种关系。高层管理者在该行业的经验对中小企业生产率的影响不显著。本文揭示了营销创新在坦桑尼亚高层管理者人力资本与中小企业生产率之间关系中的中介作用。以往的研究没有考虑创新作为将高层管理者人力资本转化为企业生产率的一种手段的作用。这些结果有助于为管理者、企业家和政策制定者提供一些实用建议。这是一项横断面研究，可能没有完全捕捉到高层管理者人力资本的所有影响。
