反思后疫情时期新结构经济学理论体系的现实危机——兼论新结构经济学体系中技术要素的重要性

Reflection on the Realistic Crisis of the Theoretical System of New Structural Economics in the Post-Epidemic Period:Also on the Importance of Technical Elements in the New Structural Economics System

市场的开放性或者说贸易的自由性是新结构经济学重要的理论基石之一,其理论体系的构建与当前经济社会背景密切相关。后疫情时期的一些特征变化将会给科学理解新结构经济学理论体系带来一定的困惑,也可能使新结构经济学的理论科学性和实践指导性建构遭受质疑。在此背景下,以要素禀赋的技术黏性视角,证明了技术要素在新结构经济学理论体系中的重要性;从要素禀赋的技术黏性出发,阐释了一个可贸易的技术条件对理解新结构经济学的增长逻辑具有重要意义。进一步审视新冠疫情对可贸易技术条件的影响后,本文认为后疫情时期面对的必然是可贸易的技术条件改变,其给后发国家依托要素禀赋和技术结构的快速升级实现经济增长产生了消极影响,进而也给新结构经济学指导现实经济发展带来危机。

The openness of the market or the freedom of trade is one of the important theoretical cornerstone of the new structural economics,and the construction of its theoretical system is closely related to the current economic and social background.The appearance of characteristic related changes in the post-epidemic period would bring some confusion to the understanding of new structural economics in a scientific way,and it might raise questions to the theoretical scientificity and practical instruction of the new structural economics.In aforementioned context,two objectives have been carried out:1.the importance of technical elements in the theoretical system of new structural economics is proved based on the perspective of technical stickyness of factor endowment;2.it has been conducted that a tradable technical condition is of great significance to the understanding of the growth logic of new structural economics based on the technical viscosity of factor endowment.After a further inspection on the impact of COVID-19 epidemic on tradable technical conditions,it is concluded that the post-epidemic period is bound to face the changes of tradable technical conditions,which has a negative impact on those underdeveloped countries that rely their rapid economic growth on factor endowments and technological structure.At the same time,crisis might have been brought out on the guidance of new structural economics to the real economic development.
