农业是国民经济的基础，农业稳则天下稳，农业兴则国家兴。水利是国民经济重要的基础设施和基础产业，是农业的命脉。从长远来看，若不能解决缺水背后的制度因素，不能在全国尤其是缺水地区建立一套有效的资源配置方式，进而形成一个节水型的经济发展模式的话，很难解决我国当前的水资源短缺问题，因旱而灾将继续恶化和扩大。本文基于阿兰·斯密德教授所提出的“状态(Situation)-结构(Structure)-绩效(Performance)”即SSP范式，试图探寻影响农业水利设施绩效差异的本源性因素，并援用相关经济学理论加以分析论证，以揭示农业水利设施绩效差异之根源就在于其自身特性不同，从而导致绩效不同，以期为我国农业水利设施建设提供一个可操作的理论分析框架和制度创新安排。%Agriculture is the foundation of national economy, and agriculture is conducive to the world steadiness. Water co-nservancy is the most important national infrastructure and basic industry , and it is the lifeblood for agriculture. From a practical and long-term perspective, if the system of the underlying factors of lack of water can not be solved all over the country, and if the effective resource allocation can not be established in dry regions in order to form a water-saving economic development , it is hard to solve the current water shortages. The drought and disaster will be continued worsening and expanding. Therefore , based on Professor Alan Smith's "Situation, Structure, Performance", the SSP paradigm, the impact for agricultural and irrigational facilities is attempted to explore-both the original and derived factors of performance differences. Related economic theories are invoked to analyze demonstrate. The result is that agricultural and irrigational facilities reveal the root causing different performa-nces with their own characteristics. At the same time, the practicable theoretical and analytical framework is provided with the systematic innovational arrangement for the establishment of agricultural water conservancy , based on different agricultural and irrigational facilities in our country.
