本文在一个两国职业选择模型中考察了渐进式贸易开放、技术外部性和个体异质性对创业形成的影响。我们发现，贸易开放导致了一个非单调的国际专业化过程，在这个过程中，创业型企业在大(小)国中的份额先增加(减少)，然后减少(增加)，全球经济呈现出先去工业化，然后再工业化的过程。当国家规模相同时，较强的技术外部性使对称均衡不稳定，产生均衡多样性，而个体足够的异质性导致对称均衡的稳定性和唯一性。
This paper investigates the impacts of progressive trade openness, technological externalities, and heterogeneity of individuals on the formation of entrepreneurship in a two-country occupation choice model. We show that trade opening gives rise to a non-monotonic process of international specialization, in which the share of entrepreneurial firms in the large (small) country first increases (decreases) and then decreases (increases), with the global economy exhibiting first de-industrialization and then re-industrialization. When countries have the same size, we also show that strong technological externalities make the symmetric equilibrium unstable, generating equilibrium multiplicity, while sufficient heterogeneity of individuals leads to the stability and uniqueness of the symmetric equilibrium.
