== 贸易路线 ==
两个市场之间如果没有共同的陆地边界，必须通过海路进行贸易，并需要设立航运线路。陆地相邻性是根据两个市场首都的位置来确定的。船队成本受海节点数量、货物数量和任何货物特定修正的影响。有效性影响贸易路线的竞争力，进而影响货物运输的数量。它将使用各自市场首都所在地区的两个最近的港口。如果其中一个国家缺乏港口，则无法建立海外贸易路线。

== 补给路线 ==
当将军及其军队被派往无法通过陆地到达的前线时，需要补给路线。这条路线将使用一个与将军及其军队的总部通过陆地相连的友好港口，并追溯到前线可以到达的最近的友好港口。船队成本基于海路节点数量、需要补给的营的数量以及将军的特性。低效的供应路线会降低将军及其部队的补给状态。如果前线被内陆包围，则无法派遣将军和军队前往前线。

== 关税 ==
Tariffs are the means where a national government extends its influence as an intermediary in the trade between national markets, if not for the means of protecting its national interests, to at the very least ensure it gets its fair share of the profits that such entails. Tariffs are set on both exports and imports leaving the national economy because yes the government is interested in its fair share and if it cannot get the revenue by means of a consumption tax it will find other means. The ratio of this tariff level is dependent on the trade policy set. A more mercantilist trade policy would seek to ensure exports exceed imports so tariffs on exports will undoubtedly be lower. Protectionism is equal in its ratio as it seeks to shelter the domestic economy from booming or busting on either side of the equation. Free Trade.

While the laws set the tariff ratio of import/exports these can be customized further in the budget screen by setting their tax levels. Tax levels don’t just bring in revenues but offer incentives to your economic actors, your pops. Lower tariffs encourage trade while higher tariffs will hinder their efficiency because well if the nation is getting a bigger cut.
