传统的内生经济增长理论通常假定代表性企业,而实际上企业是异质性的,它们的规模分布极不均衡,即大量小规模企业与少量大规模企业并存。近年来,学者们构建了一系列满足企业规模动态特征的经济增长模型,结果表明单个企业创新、知识外溢和异质性企业之间的资源再配置共同推动了经济增长,而传统内生增长理论则忽略了异质企业之间资源再配置的作用。本文根据影响企业规模的因素将文献分为三类,分别为外生冲击和外生技术进步驱动企业规模变化的文献、内生技术创新驱动企业规模变化的文献以及其他因素驱动企业规模变化的文献。这些研究使得从微观企业增长到宏观经济增长之间的联系变得更为清晰,对发展中国家的经济增长具有重要的政策涵义。
Traditional theories of endogenous economic growth usually assume representative enterprises. In fact, they are heterogeneous. Their scale distribution is extremely unbalanced. That is, a large number of small-scale enterprises and a few large-scale enterprises co-exist. In recent years, scholars have built a series of economic growth models that satisfy the dynamic characteristics of firm size. The results show that single firm innovation, knowledge spillover and reallocation of resources among heterogeneous firms jointly promote economic growth, while traditional endogenous growth theory It ignores the role of resource reconfiguration between heterogeneous enterprises. This paper divides the literature into three categories based on the factors influencing the size of the enterprise, namely the literature on exogenous impact and exogenous technological progress driving the change of firm size, the literature on endogenous technological innovation driving firm size change, and other factors driving the change of firm size . These studies make the link between micro-enterprise growth and macro-economic growth more clear and have important policy implications for the economic growth of developing countries.
