摘要： Water management and reuse at the field level are analyzed under saline, limited drainage conditions. A function relating crop yield and deep percolation flows to applied water and salinity concentration is developed. This function fits simulated data well and is tractable for theoretical and empirical analysis of irrigation economics. With a single irrigation source, irrigation water for cotton and tomatoes at first increases and then decreases with salt concentration. Drain-water reuse is found to be an efficient strategy in events of high surface-water prices and costly solutions to drainage-related environmental problems. However, blending freshwater and drainage appears plausible only under surface water scarcity.

摘要： 如同各种生物个体均有自己的生理构成和生理机制才能发育成长一样 ,任何微观经济均为一定的有机统一体 ,既有其相应的内在因素构成和内在活动的机制 ,又有其相应的自然条件和社会条件 ,方能进行正常的运作。微观经济管理的任务是把各种支配和制约经济活动的因素有机地结合起来 ,使之充分发挥各自的作用 ,以达到最佳的经济效果。我国微观经济管理总的指导思想和原则应是 ,把人类社会普遍经济规律体系。

摘要： 根据商品价格弹性理论,“薄利多销”、“高价限销”是微观价格决策中增加总收益的两种常见方法。但是,商品降价(或提价)的具体界限在实践中却很难把握,增加了生产者经营管理的难度。为此,本文提出商品价格变动的最优化数量界限,以增强经济学理论的应用性。

摘要： This study analyzes examination performance of students in three different modes or technologies of instruction in Principles of Microeconomics. The authors call the modes of instruction live, hybrid, and virtual. They found that the students in the virtual classes performed significantly worse on the examinations than the live students and female students were at a significant disadvantage in the live sections. They advise prospective online students to work harder and have more discipline than live students, especially when it comes to learning the more difficult concepts.
