73. 图十八通过列示 2015 年发展援助委员会捐助方的核心捐助占国民总收入的比例(核心捐助/国民总收入比例)，审查分担核心供资责任的问题。作为一个群体，这些国家在 2015 年捐助了 46 亿美元核心资源，约占收到的所有核心捐助的四分之三。该群体的核心捐助/国民总收入比例的中位数为 0.01%。应当指出，图十八横轴使用了对数标度。因此，所提供核心捐助数额差异很大的国家可能在图中显得比较接近。如上节所述，核心资源被用来补贴非核心资源供资的活动的支助和管理费用，因此，这样责任分担不均的情况有更加重要的意义。
73. Figure XVIII examines the issue of burden sharing of core funding by showing Development Assistance Committee donors’ core contributions relative to their gross national income (GNI) in 2015 (or core/GNI ratio). As a group, those countries contributed $4.6 billion in core resources in 2015, orsome three quart ers of all core contributions received. The median core/GNI ratio for that group of countries as a whole was 0.01 per cent. It should be noted that a logarithmic scale is used on the horizontal axis in figure XVIII. As a result, countries that provide significantly different amounts of core contributions may appear relatively close to each other in the figure. That uneven burden sharing has added importance, in view of the fact that core resources are found to subsidize support for and the management of activities financed from non-core resources, as illustrated in the previous section.
