在本文中，我们开发了一个模型，该模型近似于产品具体化运输的上游供应链。具体货物运输量在消费中占比最大的行业是石油产品，其次是政府服务、建筑和食品。总体而言，管道运输对每个部门具体货物运输总量的贡献为7%，航空运输通常低于1%，水路运输为5%，铁路和卡车运输是国内货物运输的最主要方式（各占14%）。即使与国内模式相比，国际水也是最大的模式（60%），而国际空气的贡献不到1%。
In this paper we develop a model which approximates the upstream supply chains for embodied transportation in products. The sector with the largest embodied freight transportation in consumption is petroleum products followed by government services, construction, and food products. Overall, pipeline contributes 7% to the total embodied freight movement per sector, air transport is generally under 1%, water is 5%, and rail and truck transportation are the most dominant modes (14% each) for domestic freight transportation for the average sector. International water is the largest mode (60%) even compared to domestic modes, and international air contributes less than 1%.
