摘要
从早前分析新思想的涌现过程,再到强调思想交流的重要性,现代经济增长理论对经济增长动力的认识不断深化,其微观基础日益完善。早期内生增长理论强调思想的非竞争性,在刻画新思想的创造过程的同时,也出现了与现实相矛盾的规模效应。此后,学者们基于创新的内生增长理论围绕如何消除规模效应展开讨论。但是,除了研发创新之外,微观主体之间的思想交流也是经济增长的源动力,早期理论并未将个体间的交流学习纳入创新模型中。最新的基于交流的内生增长理论认为,微观个体交流的速度以及与谁进行交流将决定总体的经济增长率。进一步的研究通过内生化思想交流速度、丰富化思想来源的设定对基准模型进行拓展,并应用于经济增长问题的解释。近年来基于交流的内生增长理论对经济增长动力的探索丰富了分析增长问题的维度,建构并巩固了增长理论的微观基础,为许多领域的研究提供了新视角、新工具。
From analyzing the process of creating new ideas to emphasizing the importance of idea flows,the endogenous growth theory has deepened the understanding of economic growth and refined the micro-foundations.While the early models of endogenous growth theory pinpoint the non-rivalry of ideas,it generates a scale effect which contradicts with the reality.Subsequent innovation-based endogenous growth models have discussed how to eliminate the scale effects.However,in addition to innovation,interaction between and learning from agents is also an important source of economic growth,and earlier endogenous theories did not incorporate idea flows into their models.In the interaction-based endogenous growth models,interaction rates and interaction objects of individuals will determine the overall economic growth rate.The follow-up research extends the interaction-based model in terms of setting the endogenous interaction rates and enriching the source of ideas,and is applied in the related economic research.The exploration of interaction-based endogenous growth theory on the source of economic growth in recent years has enriched the analysis of economic growth issues,constructed and consolidated the micro-foundation of growth theory,and provided new perspective and tools for research in many fields.
