Since entrepreneurship was conceptualised as a panacea for achieving inclusive growth in the “base of the pyramid” (BoP) regions, various ways have been explored to leverage this powerful tool, such as helping potential entrepreneurs build the resource base and capabilities. However, given the severe resources constraints in the BoP regions, such a goal is difficult to achieve. Besides, due to the high demands on personal competence, only a few people can benefit from this method, which fails to solve the problem of social exclusion in the BoP regions. Therefore, we aim to find a better way to leverage entrepreneurship to tackle the problem of the BoP regions by calling for more attention to the inclusiveness of entrepreneurship. Based on data of inclusive entrepreneurs in Zhejiang, China, we construct a three-stage model for inclusive entrepreneurship. We also apply Transaction Cost Economics to look for determinants that foster inclusive entrepreneurship and validate our main assertion that decreasing transaction cost significantly helps to increase the inclusiveness of entrepreneurship, and different phases of inclusive entrepreneurship (i.e., opportunity inclusiveness, participation inclusiveness, and sharing inclusiveness) are influenced by different sets of determinants of transaction costs.
