文献研读。这是第三个主题：新经济地理（NEG），第2篇文献。

看看

从文章中学到什么？

作者认为区域经济未来发展要讨论两个问题
(i) what do we mean by a region; (ii) what kind of interactions between regions do we want to study and how to model them?

区域经济分析的结果往往与区域的划分有关。区域划分是一个非常困难的工作，依据研究者的研究目的而定。

区域经济的本质
The idea of spatial interaction is central to regional economics. 这是让区域经济区别与宏观经济的地方。
How can (or should) a regional system be formally represented is still a matter of debate. The operationally feasible and theoretically desirable representation of a regional system is in terms of a graph.

NEG的特征和贡献
（1）One appealing feature of NEG is that it has very strong connections with several branches of modern economics.
（2）Another striking aspect of NEG is the very large number of empirical investigations it has triggered.

未来研究的方向——From two to many regions
（1）理论方面
在多区域模型中，the accessibility to markets varies across regions. Spatial frictions between any two regions are likely to be different, which means that the relative position of the region within the whole network of interactions matters.
Any change in the underlying parameters has in general complex impacts.
Any change in parameters that directly involves only two regions now generates spatial spill-over effects that are unlikely to leave the remaining regions unaffected. This in turn further affects the other regions and so on.
（2）考虑间接效应的经验研究
重心模型、空间计量、数值模拟、实验方法

短评：
什么是区域？文章从离散和连续空间两个角度提供了一些参考的文献。
从2区域到多区域，怎么做？Behrens也是先锋，他有好几篇文章。

谢谢。
