[新闻] 藤田昌久简介
简 介
藤田昌久（Fujita Masahisa）先生是日本京都大学经济研究所（KIER）城市和区域经济教授。藤田教授（1988）关于区域集聚的文章是现代经济地理学的经典文献，他与克鲁格曼（Krugman）等合作的论文光辉了屠能（Thunen）的区域经济理论。
藤田教授报告的文章，《粘滞创新下的集聚和增长：关于技术工人周期迁移的可能性》，结合经济地理学和新增长理论两大学术前沿。通过一个有两个地区的粘滞创新内生增长模型，文章解释了为什么全世界几乎所有的技术创新都是由只占15％的人口创造，从理论上证明了稳态均衡增长路径上技术工人在地区间迁移的现象。将新经济地理学运用于经济增长的研究，可以对知识沿空间的传播进行建模，突破了传统的经济增长理论的范式。
Introduction
Fujita Masahisa is the Urban and Regional Professor of Institute of Economic Research, Kyoto University. The paper about spatial agglomeration (Fujita, 1988) is the classical literature of modern economic geography. Prof. Fujita has greatly developed Thunen"s regional economy theory with Krugman et al.
This paper of Prof. Fujita, "Agglomeration and Growth with Sticky Innovations: on the possibility of skilled workers" cyclical migration", integrates the theory of economic geography and economic growth. By a two-region model of endogenous growth with sticky innovations, the paper explains that why "a small part of the globe, accounting for some 15% of the earth"s population, provides nearly all the world"s technology innovations"(Sachs, 2000). And the paper proves “steady-state growth path along which the cross-regional-migration of skilled workers occurs cyclically" (Fujita and Thisse, 2003). The integration of new economic geography and economic growth theory can model how knowledge is diffused in the spatial dimension, which greatly broke the traditional framework of the economic theory.
