英文文献摘要：
This study determines how production and trade policy distortions affected rice productivity in thirty-three rice-producing countries. A rice-productivity index for each country is constructed, and a model linking the productivity gap with policy distortions is presented. After controlling for the differences in infrastructure, openness, and human capital, this article shows that high subsidies and protection in developed countries combined with taxation of rice farming in poor countries have widened the gap in rice productivity between rich and poor rice countries.

这项研究确定了生产和贸易政策扭曲如何影响33个水稻生产国的水稻生产率。构建了各国的水稻生产率指数，并提出了将生产率差距与政策扭曲联系起来的模型。在控制了基础设施、开放程度和人力资本的差异后，本文认为发达国家的高补贴和保护加上贫穷国家对水稻种植的征税，加大了富国与穷国之间的水稻生产率差距。
