Railways,highways,waterways and airlines are four major means of transport and this study on different domestic trade contributions to the top ten urban agglomerations in China in terms of carrying capacity from 2002 to 2011 reveals that different transport means have different trade con-tributions and their correlations are either positive or negative.Generally speaking,only a few urban agglomerations in China enjoy good domestic trade contributions in terms of carrying capacity but dif-ferent means of transport do contribute to some degree to the domestic trade development and GDP. The paper finally proposes some policy-making suggestions for furthering trade development.%铁路、公路、水运和航空4种交通运输方式对中国十大城市群国内贸易贡献承载力表现出不同的强弱情况。通过从2002---2011年4种交通运输方式对中国十大城市群贸易贡献承载力比较研究发现：不同的交通运输方式对不同的城市群国内贸易贡献承载力也不一样，交通运输方式和贡献承载力两者之间正相关联动和负相关联动都存在；交通运输方式对中国十大城市群的贸易贡献承载力较强的城市群个数太少，贡献承载力一般的城市群个数较多。但是交通运输方式在不同程度上促进国内贸易的发展，提高贸易总额和国内生产总值，文中分别从4种交通运输方式提出相关的政策和建议，为推进贸易发展加快步伐。
