STRUCTURAL, EXPERIMENTALIST, AND DESCRIPTIVE APPROACHES TO EMPIRICAL WORK IN REGIONAL ECONOMICS
概述了区域经济学实证工作的三种方法（结构性、实验性、描述性），并以集聚效益和生产率提升为例，分析各方法的优缺点，探讨未来研究方向。
ABSTRACT The three general approaches to empirical work in economics are structural, experimentalist, and descriptive. This paper provides an overview of how empirical work in regional economics fits into these three categories. In particular, I examine a single issue in the field, the nature of agglomeration benefits and the productivity gains from agglomeration, and analyze the advantages and drawbacks of following each of these three empirical approaches. I also discuss potentially fruitful ways empirical work in regional economics might advance.
