I construct a hybrid model of endogenous and semi-endogenous growth to analyze the impact of labor reallocation between capital-augmenting R&D and final-goods production. By affecting the price of capital-intensive goods, factor-augmenting technical change or capital deepening will induce intersectoral labor reallocation between capital-augmenting R&D and final-goods production. The intersectoral labor reallocation in this paper can reverse some seemingly fundamental implications of the neoclassical growth models. In particular, given the gross complementarity of capital and labor, intersectoral labor reallocation implies that capital-augmenting technical change or capital deepening decreases the labor share, while labor-augmenting technical change increases the labor share. In the present model, a strengthening of the capital-augmenting R&D spillover effect helps to increase the importance of investment-specific technology and reduce the relative price of investment goods.

我构建了一个内生和半内生增长的混合模型，以分析资本增值研发和最终产品生产之间劳动力重新分配的影响。通过影响资本密集型产品的价格，要素增强型技术变革或资本深化将导致资本增强型研发与最终产品生产之间的部门间劳动力再分配。本文中的部门间劳动力重新分配可以扭转新古典增长模型的一些看似基本的含义。特别是，鉴于资本和劳动力的总互补性，部门间劳动力再分配意味着资本增强型技术变革或资本深化会降低劳动力份额，而劳动力增强型技术变革会增加劳动力份额。在目前的模型中，
