Production efficiency is a key determinant of economic growth and demonstrates how a country uses its resources by relating the quantity of its inputs to its outputs.When a natural hazard-induced disaster strikes,it has a devastating impact on capital and labor,but at the same time provides an opportunity to upgrade capital and increase labor demand and training opportunities,thereby potentially boosting production efficiency.We studied the impact of natural hazard-induced disasters on countries’ production efficiency,using the case study of hurricanes in the Caribbean.To this end we built a country-specific,time-varying data set of hurricane damage and national output and input indicators for 17 Caribbean countries for the period 1940-2014.Our results,using a stochastic frontier approach,show that there is a short-lived production efficiency boost,and that this can be large for very damaging storms.

甘蓝型油菜(Brassica.napus L.)是我国重要的油料作物,长江流域是我国油菜主要种植区。由于南方的气候是冬季湿润多雨,因而易发生涝灾和湿害,严重影响油菜生产,使生产成本提高,产量下降。目前生产上减轻油菜湿害的方法有两种:栽培措施,控制土壤水分;育种措施,提高油菜品种的耐湿性。通过培育优质、高产、高耐湿的油菜品种,可以在我国水早轮作的冬季进行直播栽培,从而大大的减少农民的工作量,降低翻耕
