我们使用中国水库灌溉系统的原始用水群体（WUG）数据来检验水价政策对农民节水行为的影响。在集团层面引入计量水价来取代基于区域的定价，引发了制度变革，以防止每个成员在计量水价水平适中时过度用水。根据初始条件，多种变革途径会导致新的制度安排，所有这些都有助于节水。然而，当价格定得足够高时，许多农民就会退出用水小组进行私人灌溉。这种趋势与剩余成员不进行制度变革并且最终不节约用水的可能性增加有关。这可能是由于剩余成员的管理困难增加，他们的田地被前成员分开，而这些前成员现在选择退出整个 WUG 的私人灌溉。因此，我们没有找到证据表明水库水在高水价水平下得到了节省。
We use original water user group (WUG) data from a reservoir irrigation system in China to examine the effect of water pricing policies on farmers’ water saving behaviors. The introduction of volumetric water pricing at the group level, to replace area-based pricing, induces institutional change to prevent each member's overuse of water when the volumetric price levels are moderate. Depending on the initial conditions, the multiple pathways of change lead to new institutional arrangements, with all of them contributing to water savings. However, when the price is set high enough, many farmers exit a WUG for private irrigation. This tendency is associated with an increased probability that the remaining members do not undertake institutional change and that they do not end up saving water. This may be due to the increased management difficulties among the remaining members whose fields are separated by former members who have now opted out for private irrigation across the WUG. As a result, we do not find evidence that the reservoir water is saved at high volumetric price levels.
