新新经济地理学多地区异质结构的量化分析:文献综述

Quantitative Analysis of the Multi-Regional Heterogeneity of the “New” New Economic Geography:A Literature Review

近年来由于新新贸易理论的发展,人们得以建立多地区异质性企业模型,从理论上研究产品、要素以及技术在地区间的流动摩擦对经济活动的影响,并结合现实数据做出更准确的量化估计,从而形成一个新的经济学研究方向:新新经济地理学。本文通过梳理发现,新新经济地理学相关文献基本是在Eaton和Kortum(2002)多地区模型的生产和市场结构两个设定基础上进行延展,从而与生产网络、市场结构、全球价值链、人口流动、空间规划、搜寻摩擦以及动态决策等领域产生联系,拓宽了经济运行的解释渠道和政策制定的工具空间。我们试图归纳出新新经济地理学在各方向的发展脉络,并展望未来可能的研究方向。

In recent years, due to the development of the “new” new trade theory, multi-regional models embedding heterogeneous firms have been established in order to theoretically discuss the impact of goods, factors and technological flow friction on all aspects of economic activity, combining real data to develop a more accurate quantitative estimate and thus leading to a new branch: the so-called “new” new economic geography.This paper reviews the link between this literature and issues relating to production networks, market structure, global supply chains, labor mobility zoning, search friction and dynamic decision-making, etc.It finds that the researches amplify the economic system propagation and expand the toolbox for policy making by extending the Eaton-Kortum multi-regional model in terms of production and market structure.Hence, it attempts to summarise how the “new” new economic geography has been developing in each field and then points out possible future guidance in terms of research.
