科学在公共政策中发挥什么样作用？例如，医学科学在卫生政策中发挥什么样作用，生态科学在环境政策中发挥什么样作用，转基因科学在食品政策中发挥什么样作用？这一问题一直是政策研究中的一个重要话题。对此，经验研究不足。
公共政策双周论坛第十一期拟邀请北京航空航天大学公共管理学院副教授、博士生导师、环境治理与可持续性科学研究所所长杨立华将在埃莉诺•奥斯特罗姆的IAD框架基础之上，结合中国北方沙漠化个案的经验研究，试图尝试性对“科学测量的范围和实效”之间关系进行回答，并在此基础上发展出更为一般性的理论框架。

摘要： Science plays an important role in desertification control and other types of ecological and environmental management. People often intuitively assume that higher extents of the adoption and implementation of scientific measures must lead to increased effects of science application. Based on an empirical case study of desertification control in northern China, however, this study found that the relationship between the extent and effect of scientific application followed a cubic rather than a simplified linear relationship and was influenced by a set of factors, including biophysical conditions, science itself, interactions between organizations and social actors, and other supporting elements. The study also developed a framework for analyzing several factors that influence the extents and the effects of scientific application and the deviation between the two. These findings provide an outline for improving the adoption and implementation of scientific measures in desertification control and other types of ecological and environmental management.
