The Effects of Well Management and the Nature of the Aquifer on Groundwater Resources
比较中国农村集体水井管理与私人水井管理下的地下水使用差异，发现集体管理下用水更少，但含水层连通性会削弱节水激励。
We compare groundwater use under collective well management in China, where village leaders allocate water among households, and under private well management where farmers either pump from their own wells or buy water from wells owned by other farmers. Villages are divided into connected or isolated groups depending on whether there are lateral groundwater flows between aquifers underlying a village and neighboring ones. In rural China, households under collective well management use less water. Even under collective management, households located in connected villages use more water, indicating that the connectedness of the aquifers may undermine leaders’ incentives to conserve water.
