农田面源污染团队式治理方法初探

我国农田面源污染的环境经济治理方式还不健全,急需适应我国农业特征的面源污染治理手段。现阶段环境税费政策通过对农业投入的控制,容易影响农户农业生产的积极性,而且还存在一定的技术难度和设备成本约束。团队式治理方法是一种更直接的面源污染监管手段,通过将农户组成团队,比管理单个农户节约成本;通过一定的奖惩措施激励农户主动调整污染排放水平;给定的合约条件约束了农户在重复博弈下的"搭便车"行为,保证了团队的存续。

Reducing Farmland Nonpoint Source Pollution by Team Approaches

Environeconomic management which is oriented to agriculture development is urgently needed since pollution control means of farmland nonpoint source (NPS) in China is still not sound. Current environment taxes for NPS will affect aggressive of agriculture production because of technique difficulty and cost stipulation. Team approaches as a direct NPS management are more cost effective than the management on single farmer, which can provide incentives to make farmers active to adjust emission level by certain prize and punishment measures, with contract conditions to assure team's sustainability.
