Explaining Irrigation Technology Choices: A Microparameter Approach
利用田间数据，采用微观参数方法分析经济、环境和制度因素对灌溉技术选择的影响，发现水价并非最重要因素，物理和农艺特征更为关键。
Abstract Water price reforms are increasingly being used to encourage improvements in irrigation efficiency through technology adoption. A microparameter approach based on field‐level data is used to assess the effect of economic variables, environmental characteristics, and institutional variables on irrigation technology choices. The results show that water price is not the most important factor governing irrigation technology adoption; physical and agronomic characteristics appear to matter more. The results demonstrate the importance of using micro‐level data to determine the effects of asset heterogeneity and crop type on technology adoption.
