本文提出两个研究问题：（1）合作环境治理是否能改善环境结果？（2）在这方面，具有不同责任、形式化和代表性水平的公共支持的合作团体如何比较？使用一个有代表性的流域质量数据系列，美国环保署的国家河流和溪流评估和可涉水溪流评估，结合流域管理制度数据库编码的这种分析，我测试合作治理和流域质量之间的关系为357流域。由于这些是观察性数据，因此使用多水平倾向评分匹配方法来控制选择偏倚。使用增广逆倾向加权估计，我估计的平均治疗效果的治疗六个不同的水质和栖息地条件指标。合作流域组被发现，以改善水化学和流栖息地条件。然后，我使用分层线性回归模型来研究如何组的责任，成员的多样性，和正式化影响的预测影响的协作组。参与管理活动的团体（与协调或规划相比）可以取得更大的环境收益。有限的差异被发现与组协调员的存在，增加目标的特异性，或更大的利益相关者的多样性。
This paper addresses two research questions: (1) Does collaborative environmental governance improve environmental outcomes? and (2) How do publicly supported collaborative groups with different levels of responsibility, formalization, and representativeness compare in this regard? Using a representative watershed quality data series, the EPA’s National Rivers and Streams Assessment and Wadeable Streams Assessment, in conjunction with a watershed management regime database coded for this analysis, I test the relationship between collaborative governance and watershed quality for 357 watersheds. Since these are observational data, a multilevel propensity score matching method is used to control for selection bias. Using an augmented inverse propensity weighted estimator, I estimate the average treatment effect on the treated for six different water quality and habitat condition metrics. Collaborative watershed groups are found to improve water chemistry and in-stream habitat conditions. I then use hierarchical linear regression modeling to examine how group responsibilities, membership diversity, and formalization affect the predicted impact of a collaborative group. Groups that engage in management activities (in comparison to coordination or planning) are found to achieve greater environmental gains. Limited differentiation is found with regards to the presence of a group coordinator, increased goal specificity, or greater stakeholder diversity.
