The Measurement of Average Farm Size
探讨了定义农场和选择合适规模度量时的问题，详细介绍了中点聚合点这一平均规模测量方法，并以英格兰和欧盟成员国的农业持有为例进行说明。
Comparisons are regularly drawn between the average sizes of farms in particular countries or regions and in different farm‐type categories. Indeed average farm size is often considered to explain (or create expectations of) changes or differences in technical or economic efficiency through time or between countries. There are, however, a number of issues involved in specifying what is meant by a farm and in choosing a suitable measure of farm size. These are examined prior to a discussion of various measures of average size, one of which (the mid‐aggregate point) is described in some detail. The measures are illustrated with reference to agricultural holdings in England and in the Member States of the European Union.
