摘要：为保证水资源高效分配与利用，政策设计者运用了各种策略，包括价格制定、灌溉水分散化管理以及强化水权等。这些策略中，多数已单独实施，但并未考虑不同策略间的互补关系。本文利用离散选择模型，分析了灌溉需水管理措施的组合范围以及农户对这些措施的接受能力。从地方灌溉水管理的角度来讲，是否采取用水户协会形式的灌溉水集体管理，这需要谨慎考虑。根据权利持有时间、特性以及可转移性便可确定水权。最终，考虑了四种水资源定价方法（面积水价、农作物水价、街区水价与水量水价）。利用选择实验，本文提出了不同水权情景、不同价格水平以及不同地方灌溉水管理方式下的最优化水资源定价方法。结果显示，强化水权情景下，人们更偏向按照用水量收费（水量水价），然而，用水户协会的出现会削弱此种偏向。此外，分析结果表明，合理利用组合式需水管理策略会增强人们在变化情景下的支付意愿。

Abstract: To ensure efficient water allocation and use, policy designers have adopted various strategies, including price setting, decentralising irrigation water management or improving water rights. Most of these strategies have been applied individually, without considering the complementary relationships between them. This paper uses a discrete choice model to analyse the scope for combinations of tools for irrigation water demand management and farmers' acceptance of these. In terms of local irrigation water governance, the presence or absence of collective irrigation water management, in the form of a Water Users Association, is considered. Water rights are specified in terms of the duration and quality of the entitlement and its transferability. Finally, four types of water pricing methods (area, crop, block and volumetric pricing) are considered. Using a choice experiment, we elicit the most preferred water pricing method, under different water rights situations, at different price levels and under various contexts for local irrigation water governance. Our results indicated that under conditions of improved water rights, preference for volumetric pricing increases, whilst the presence of a Water Users Association reduces this preference. Furthermore, it was found that using an appropriate combination of water demand management tools considerably increases the willingness to pay for a change in scenario.
