A study by Charles Kenny and Andy Sumner for the Center for Global Development in Washington, DC, suggests that the MDGs not only boosted aid flows, but also redirected them toward smaller, poorer countries, and toward targeted areas like education and public health. However, aid was not directly linked to performance and results, and it is much more difficult to know whether it had the desired impact overall.
事实上，MDG最显而易见的影响可能就在于富国向穷国的援助流。华盛顿全球发展中心的查尔斯·肯尼（Charles Kenny）和安迪·萨姆纳（Andy Sumner）的研究表明，MDG不但刺激了援助流，还将援助流定向至更小、更穷的国家以及教育和公共卫生等更为具体的领域。不过，援助与表现和效果并不直接相关，了解援助是否达到了理想效果要困难得多。
