This investigation contributes to the relevant literature by building a preliminary economic model of the biohydrogen with circular economy (CE) to evaluate the effects of developing biohydrogen which is an important driven power of CE. Value flows of secondary materials are estimated and added to the IO database and circularity are also added to GTAP model. The results demonstrate that the GTAP model modified with biohydrogen of CE is valid. Malaysia will be the most productive country if it developed CE, and it will have the highest output value of biohydrogen industry compared to other countries. CE will outperform LE in developed regions, whereas LE will outperform CE in developing regions. Japan will be the first country to realize CE with negative CE gap. The results for Japan indicate the effectiveness of the modification of GTAP model to incorporate CE mechanism and biohydrogen. The biohydrogen industry will have an important role in the transition to CE.

这项研究通过建立循环经济（CE）的生物氢的初步经济模型，以评估开发生物氢的效果，这是CE的重要驱动力，从而为相关文献做出了贡献。估算辅助物料的价值流并将其添加到IO数据库中，并将圆度也添加到GTAP模型中。结果表明，经CE生物氢修饰的GTAP模型是有效的。如果发展CE，马来西亚将成为生产力最高的国家，与其他国家相比，它将拥有最高的生物氢产业产值。在发达地区，CE的表现将优于LE，而在发达地区，LE的表现将优于CE。日本将成为第一个实现CE差距为负的CE的国家。日本的结果表明，修改GTAP模型以纳入CE机制和生物氢的有效性。生物氢工业将在向CE过渡中扮演重要角色。
