Exporting intensity, human capital and business ownership experience
研究人力资本（尤其是先前商业所有权经验）与出口强度之间的关系，发现同时拥有多项业务的创业者出口强度更高，基于加纳432名创业者的调查数据。
This article examines whether human capital, particularly prior business ownership experience, is associated with the opportunity exploitation outcome relating to the intensity of exporting. A distinction is made between entrepreneurs who acquire their business ownership experience sequentially (that is, serial entrepreneurs) or concurrently (that is, portfolio entrepreneurs). Using survey data from 432 entrepreneurs in Ghana, this study explores whether human capital theory relating to prior business ownership experience is associated with superior exporting intensity. Notably, portfolio entrepreneurs reported higher exporting intensities than other entrepreneurs. The case for customized assistance to each type of entrepreneur with regard to prior business ownership experience is made.
