Adoption and abandonment of irrigation technologies
研究了七种灌溉技术的采用和放弃过程，开发了估算技术周期的方法，并应用于以色列和加沙地区的柑橘园数据，发现技术周期因技术而异但各地区相似，且扩散受水价、作物价格和补贴等经济变量显著影响。
Abstract Adoption and abandonment processes are analyzed for seven irrigation technologies. A procedure is developed to estimate the technology cycle and applied to data available for citrus groves in several regions of Israel, and Gaza. The technology cycle was used to estimate diffusion‐abandonment patterns for several irrigation technologies that have been abandoned. Results suggest that the technology cycle is unique to each technology and similar in length for all regions. Results predict the year of full abandonment of each technology. For modern technologies still in the diffusion phase, a logistic equation was fitted to the aggregated data. Results suggest that diffusion is significantly affected by economic variables such as water price, crop yield price, and subsidy for irrigation equipment. Use of the estimated equations for policy purposes suggest that water price and subsidy for irrigation equipment can be used to control the diffusion process (speed and ceiling) of the irrigation technologies.
