本文确定了1973- 1999年期间孟加拉国稻米生产增长的来源。主要的贡献者被认为是水稻种植区从地方品种到现代品种的转换。根据模拟得出的最重要结论是，只有通过提高现代水稻品种的产量，才能维持目前的人均产量水平。人口控制被发现有显着的长期效益，而更快的转换剩余面积的现代品种有重要的短期回报。然而，后两项行动只能补充而不能取代提高现代品种产量的努力。(C)2001爱思唯尔科技有限公司版权所有。
This paper identifies the sources of growth in rice production in Bangladesh over the 1973-99 period. The main contributor was found to be the conversion of rice growing areas from local to modem varieties. The most important conclusion, based on simulations, is that the current level of per capita production can be sustained only through increased yields of modem rice varieties. Population control is found to have significant long-run benefits, while faster conversion of remaining area to modem varieties has important short-run payoffs. The latter two actions, however, can only complement but not substitute efforts to increase the yields of modem varieties. (C) 2001 Elsevier Science Ltd. All rights reserved.
