摘要

本文根据对特拉荣省162户农户的调查,比较和评价了作物转换模式(从水稻到蔬菜)的经济效益。结果表明,这些农户的收入是水稻农户的3倍,约为570万越南盾/0.25英亩/年。此外,本研究还运用回归分析方法识别和量化了影响转换模式经济效率的因素。结果证实了蔬菜作物、稻菜轮作作物、劳动力成本、年龄和户主种族之间的相互作用。特别是,家庭对气候变化的意识对模型的经济效率产生了积极的影响。最后,提出了提高适应气候变化的作物转种模式经济效益的对策。

ASSESSING ON THE ECONOMIC EFFICIENCY OF THE CLIMATE CHANGE ADAPTION MODELS IN TRA VINH: THE CROP CONVERSION MODEL
According to the survey of 162 farm households in Tra Vinh province, this article compares and evalutes the economic efficiency of the crop conversion model  (from rice to vegetable). The results show that the incomes of these farm households were 3 times higher than those of rice farm households, approximately 5.7 million VND/0.25 acre /year. In addition, the regression  analysis was applied in this study to identify and quantify the factors influencing the economic efficiency of the conversion model. The results confirm the interaction between vegetable crops, rice – vegetable rotational crops, labor cost, age and the ethnicity of  householders. In particular, the households’ awareness of climate change has a positive impact on the economic efficiency of the model. Finally, the research suggests some solutions to the improvement of the economic efficiency of the crop conversion model which adapts to climate change.
