公共事务的积累只是为制度化解决提供了必要性,当政者维护政权的根本利益需要决定了公共事务处理的优先序列。客观问题的属性和解决的迫切程度只有在政府最高层统治集团认为维系权力存续的手段具备充分的支撑条件时,才会愿意在正式制度上进行调整,为解决问题提供制度供给。新中国成立后很长一段时间内,我国环境问题并不突出,中央政府根据社会主要矛盾需要制定了以发展经济为重心的制度体系。这种制度结构使地方政府和辖区企业形成了利益共容关系。为适应竞争的需要,地方政府庇护辖区企业环境行为,机会主义地执行环境管理制度,使环境问题积累成为影响安全价值的显著因素。在国内外政治压力下,中央政府最终做出了战略调整,地方政府在中央政府制度调控下,自发地合作治理环境问题。  相似文献

Abstract: While transboundary flood events have become more frequent on a global scale the past two decades, they appear to be overlooked in the international river basin (IRB) cooperation and management arena. The present study therefore combined geopolitical measures with biophysical and socioeconomic variables in an attempt to identify the IRBs with adequate institutional capacity for management of transboundary floods. It also classified basins that would possibly benefit from enlarging the institutional capacity related to transboundary floods. Of the 279 known IRBs, only 78 were represented by a transboundary rivers institution. A mere eight of the 153 identified institutions had transboundary flooding listed as an issue in their mandate. Overall, 43 basins, where transboundary floods were frequent during the period 1985‐2005, had no institutional capacity for IRBs. The average death and displacement tolls were found to be lower in the 37 basins with institutional capacity, even though these basins experienced twice as much transboundary floods with significant higher magnitudes than those in basins without institutional capacity. Overall, the results suggested that institutional capacity plays a role in the reduction of flood‐related casualties and affected individuals. River basins such as the Juba‐Shibeli, Han, Kura‐Araks, Ma, Maritsa, Po, Coco/Segovia, Grijalva, Artibonite, Changuinola, Coatan Achute, and Orinoco experienced more than one transboundary river flood, but have not yet set up any institutions for such events, or signed any appropriate treaties focused on floods. These basins were therefore recommended to consider focusing attention on this apparent lack of institutional capacity when it comes to managing transboundary flood events.  相似文献

农村社区小型水利设施合作供给意愿的实证   总被引:5,自引:0,他引:5  
本文基于社会资本视角,在现有文献的基础上,将社会资本分为社会网络、社会信任、社会声望、社会参与四个维度,利用6省区600户农户的调查资料,运用logistic模型分析了农户参与小型水利设施合作供给意愿的影响因素。研究结果表明,社会资本对农户小型水利设施合作供给意愿有积极作用。社会资本不同维度中,除社会声望对合作意愿影响不显著外,社会网络、社会信任、社会参与对农户参与小型水利设施合作供给意愿均有显著正向影响,说明农户的合作供给实现应该充分利用社会资本。此外,农户参与小型水利设施合作供给意愿还受其他因素影响,其中合作认知和灌溉面积对农户参与小型水利设施供给的合作意愿有显著正向影响,而家庭收入、是否偷水和用水纠纷对合作意愿有显著负向影响。提出应通过培育农户社会资本、规范社区用水环境、提高合作认知程度等措施,提高农户参与农村社区小型水利设施合作供给积极性的政策建议。  相似文献

The problem of climate change is a global challenge.It is closely associated with social development and human survival,and it has a significant impact to all countries on energy development,economic competitiveness,technological innovation,and way of life.In recent years,with the rapid economic development in China,there is a rumor that the rapid growth of China’s carbon dioxide emission offset the efforts of the international community in reducing emissions,and China should bear the international responsibility corresponding to its significant role in greenhouse gas emission,which obviously are unfair and not objective.As this paper reveals,"China environment responsibility" that is the socalled "China environment threat" or theories,China has made a positive contribution to addressing the climate change in the past and China will still be the backbone on the protection of global climate in the future.  相似文献

The idea that natural selection can be meaningfully applied at the group level may be more important than previously thought. This perspective, a modern version of group selection, is called multilevel selection. Multilevel selection theory could incorporate previous explanations for the evolution of cooperation including kin selection. There is general agreement that natural selection favors noncooperators over cooperators in the case of an unstructured population. Therefore, the evolution of cooperation by multilevel selection often requires positive assortment between cooperators and noncooperators. The question is how this positive assortment can arise in the ecological meaning. We constructed an individual-based model of multilevel selection and introduced migration and evolution. The results showed that positive assortment was generated especially when a migration strategy was adopted in which individuals respond specifically to bad environmental conditions. It was also shown that the founder effect in the evolutionary process could further facilitate positive assortment by working with migration. We analyzed assortment by using relatedness defined in group-structured populations. The fact that cooperation was achieved by such migration and by the founder effect highlights the importance of sensitiveness to the ecological environment and of fluctuations in group size, respectively.  相似文献
