我国化肥价格波动与农民收入关系的实证分析

本文利用1978～2008年的时间序列数据,运用脉冲响应函数和方差分解技术考察化肥价格波动与农民收入之间的关系,发现化肥价格的波动与农民收入变化之间存在着双向的因果关系,即化肥价格的上涨导致农民增收缓慢,而化肥价格上涨的根本原因在于＂需求拉动＂和＂成本推动＂。今后必须从需求和供给两方面采取对策：一方面通过建立化肥直接补贴制度和化肥储备制度,从需求上控制化肥价格上涨;另一方面通过采用新型化肥生产技术和给予化肥生产企业生产用能以优惠政策,从供给上控制化肥价格上涨。

An economic evaluation of market development programmes for US dairy products

‘This study measured the effectiveness of US dairy export promotion programmes on increasing foreign demand and enhancing producers’ revenues. An import demand equation based on panel data was used to test whether export promotion has a positive and significant impact on US dairy exports. The effects of various promotion scenarios on the dairy market were then simulated, and benefit–cost ratios (BCRs) for these programmes were estimated. There were three key findings. First, the combined effort of public and private dairy export promotion expenditures had a positive and statistically significant impact on demand for US dairy products in the world market. The findings indicated that export promotion stimulated total dairy exports by 4.14 billion pounds, on average, per year, which represented 55.8% of total exports. Second, US dairy export promotion has been highly profitable for the nation’s dairy farmers. The calculated BCRs, based on assumed elasticity of supply, ranged from a low of 8.54 for the most elastic assumption to a high of 30.12. Third, from an optimality standpoint, dairy farmers are underinvesting in export promotion. The marginal BCRs ranged from a low of 3.79 to a high of 15.22, which means that, at the margin, increasing export promotion expenditures would be profitable for dairy farmers.     

谈金安桥水电站左岸护岸边坡开挖的控制爆破

金安桥水电站左岸护岸边坡开挖爆破区环境复杂,紧挨将要拆除的下游围堰,在爆破时不能丝毫破坏其下游围堰。为了确保下游围堰、基坑抽水设备的安全,采用预裂爆破、孔间微差爆破、孔内微差爆破,选用较为合理的爆破参数控制爆破,顺利完成了左岸护岸边坡开挖爆破工作,为下游围堰的如期拆除创造了条件。
