“过早”去工业化的技术差距模型

A Technology-Gap Model of ‘Premature’ Deindustrialization
American Economic Review · 2024 · Ippei Fujiwara、Kiminori Matsuyama

中文摘要

我们提出一个简约机制来解释过早去工业化(PD)的产生。在基准模型中,鲍莫尔效应驱动了制造业份额的驼峰形路径。各国由于部门特定采纳滞后时间的差异而遵循不同路径。在各国仅存在技术差距差异的PD条件下,该条件意味着跨国生产率离散度在农业中最大。此外,当校准以匹配Rodrik(2016)的发现时,该离散度在制造业中最小。在三个扩展中,我们加入恩格尔效应、国际贸易以及后发工业化国家的追赶,以证明该机制的稳健性。

Abstract

We propose a parsimonious mechanism for generating premature deindustrialization (PD). In the baseline model, the Baumol effect drives the hump-shaped path of the manufacturing share. Countries follow different paths due to the difference in the sector-specific adoption lags. The condition for PD under which countries differ only in technology gap implies that the cross-country productivity dispersion is the largest in agriculture. Moreover, when calibrated to match Rodrik’s (2016) findings, it is the smallest in manufacturing. In three extensions, we add the Engel effect, international trade, and catching up by late industrializers, to demonstrate the robustness of the mechanism. (JEL F11, L16, L60, O14, O33)
