摘要

本研究考察了大米贸易的驱动因素。该分析使用了标准的比较优势模型，即Heckscher-Ohlin-Vanek （HOV）框架，并辅以引力型方程。利用泊松拟极大似然（PPML）对2002 ~ 2020年的数据进行估计，分析结果基本证实了HOV模型的预测。结果表明，耕地面积、GDP、距离、降水和作物季节温度对水稻贸易动态有显著影响。结果表明，影响水稻贸易的主要因素是降水，而非蓝水供应。然而，农业用水压力阻碍了出口，鼓励了进口。

What explains rice exports? An analysis of major rice-exporting countries

This study examines the drivers of rice trade. The analysis uses the standard comparative advantage model, the Heckscher–Ohlin–Vanek (HOV) framework, supplemented with a gravity-type equation. Using the Poisson pseudo-maximum likelihood (PPML) estimation for data from 2002 to 2020, the analysis broadly confirms HOV model predictions. Results indicate that arable land, along with GDP, distance, precipitation and crop season temperature, significantly influences rice trade dynamics. The results showed that the precipitation play a key role in influencing the rice trade rather than the blue water availability. However, agricultural water stress discouraged exports and encouraged imports.
