IMPLEMENTING REPRESENTATIONS OF SPACE IN ECONOMIC GEOGRAPHY*
研究了经济理论中空间问题日益重要时，如何表征距离和邻近性，以及不同表征方式对建模推断的影响，并与其他学科（如生态学）进行比较。
ABSTRACT Since spatial issues have become more important in economic theory, it is of interest to examine how space is represented. In empirical terms, this concerns at least the representation of distance and proximity. Both of these may be represented and operationalized in a number of ways, with possible consequences for inferences when modeling. This question is related to the representation of spatial entities, and itself plays into the treatment of spatial dependence as substantive and/or just a nuisance. Because other disciplines face similar questions—for example ecology or epidemiology, their conceptualizations and operationalizations of space will also be used for comparative purposes.
