貿易節點

贸易产品的生产和贸易是国家的三大收入来源的其中两个,第三个是税收。每个省份都会生产贸易产品,贸易产品能直接提供生产收入。产品的贸易值则会进入贸易节点系统。在贸易节点系统中,贸易值会被由上游转移到下游,最终被商人收集,成为国家的贸易收入。

摘要

游戏中的贸易系统概括如下:

  • 分布在全球互相连通的贸易节点组成了全球贸易网络。每个贸易节点都为一组在地理上接近的省份的贸易活动提供了场地。在全球贸易网中的贸易值可在各个贸易节点之间单向流动,但贸易值在到达终点节点时便不再流动了。这些贸易节点之间的联通关系是固定的,同时,这些联通关系在游戏过程中是不能被修改的。
  • 贸易值代表贸易节点每月本地生产的产品的价值和来自上游节点的产品的价值之和。贸易值由每个省份生产的产品的数量和单价所决定。一个贸易节点中所有省份的贸易值凑到一起便是该节点的本地贸易值。“贸易”地图模式分开显示了本地贸易值和来自上游节点的贸易值,同时,省份交互界面中的贸易标签页展示了当前贸易节点的贸易值总和。
  • 贸易力代表一个国家对贸易节点中的贸易值的控制力。各个国家的贸易力在当前节点总贸易力中所占的比重决定了如何处理当前节点的贸易值。对各个国家来说,贸易力既可用于“持有”当前节点中的贸易值(如果该国家有派商人到当前节点收集贸易值,或当前节点是该国家的贸易本埠),也可用于将当前节点的贸易值“转移”到下游节点(如果该国家有派商人到当前节点转移贸易值,或在没有派商人的情况下,当前节点是该国家贸易本埠的上游节点)。贸易力由省份、轻帆船和商人产生。特定的理念、事件和修正同样也会影响一个国家在各个节点中的贸易力。
  • 商人团既可用于在各个贸易节点“收集”贸易值(具体数值由该国家的贸易力在当前贸易节点总贸易力中所占的比重决定),也可用于将各个贸易节点的贸易值往特定方向“转移”。

贸易值来源

参见:产品
The Krakow trade node, showing all sources of local trade value.

所有的贸易收入都源自“省份贸易值”。

本地贸易值

一个省份的贸易值等于该省份生产的Local goods produced产品的数量与该产品的当前价格之积。玩家可在省份窗口中查看该值。贸易值决定生产收入,但它本分并会收到生产效率或省份自治度的影响。如需获取省份生产的产品的详细信息,请查阅产品页面。值得一提的是,Government republic.png商业共和国和贸易公司会给它们所在贸易节点中的所有省份提供贸易产品生产数量加成,加成幅度与该国在该节点的总贸易力中所占的份额成正比,最多到+50%

一个节点中所有省份的贸易值之和为该节点的本地贸易值本地贸易值既会展示在贸易节点窗口中,也会展示在统计报表和国家总览页面的贸易标签页中。

总贸易值

一个贸易节点的总贸易值为“本地贸易值”与来自上游节点的“贸易输入”之和。关于“贸易输入”的详细内容,请查阅转移贸易值

贸易节点和贸易力

世界上的每个省份都属于且只属于一个特定的贸易节点。该节点的贸易值等于所有属于该节点的省份的贸易值之和。此外,大多数的节点都有一个或多个上游节点以及一个或多个下有节点。所有节点以这种方式连接成全球的贸易网络(技术上来讲,这是个有向无环图)。一部分没有上游的节点(加利福尼亚,暹罗和埃塞俄比亚等)称为起点节点。三个没有下游的节点(英吉利海峡,热那亚和威尼斯)称为终点节点

贸易力相关:争抢贸易值

各国使用Trade power.png贸易力来争抢操纵贸易值流向的权力。贸易力的绝对值大小无关紧要;真正的重要的是该国以及他的盟友在与其他国家竞争时,在总贸易力中的相对占比

每个国家的贸易力(包括省份贸易力,来自轻帆船的贸易力等)都受该国的Trade power.png全球贸易力修正影响。

收集贸易值

每个国家都有一个贸易总埠。游戏开始时,所有国家的贸易总埠都是它们的首都,而且在游戏过程中通常保持不变。在一个国家在贸易总埠所处的贸易节点会获得额外的Trade power.png+5贸易力,同时,该国也会在该节点自动收集贸易值。如果玩家拥有Wealth of Nations.png国富论扩展包,那么玩家可以消耗Diplomatic power.png200点外交点数改变贸易总埠所在地。如果一个国家的首都和贸易总埠在同一个省份,那么在移动首都时,贸易总埠也会被移动到首都的新所在地(强制移动,但不需要消耗外交点数)。

此外,各个国家还可通过派遣Merchants.png商人团来到各个节点收集贸易值。然而,如果一个国家在贸易本埠以外的节点收集贸易值,那么它就会在这个节点承受-50%的贸易力惩罚。这个惩罚是个累乘修正,作用于其他贸易力修正生效之后。[1]

当一个国家在一个节点收集贸易值时,它能获得该节点总贸易值的一部分,这一部分的大小计算方式如下

计算出来的结果会乘以1+该国的Trade efficiency.png贸易效率,得到的积会转化成等额的Gold Icon.png金币并成为该国每月贸易收入的一部分。

每个在执行收集贸易值的国家都会与其他执行贸易收集执行转移贸易的国家竞争。

转移贸易值

Trade node window, showing the tooltip for trade forwarded out of the node. The cursor is hovering over the red part of the pie chart.

对一个国家来说,在一个贸易节点转移贸易值的定义是往该节点派遣商人团执行“转移贸易值”的任务或在该节点的下游(包括下游的下游,下游的下游的下游……)执行收集贸易值操作。转移贸易值有以下两种形式:

  1. 该国利用自己的贸易力增大该节点往下游输出的贸易值的份额。
  2. 该国使用商人团来转移贸易值以增加该节点往特定下游节点输出的贸易值的份额。
牵引贸易值往下游流动

所有在一个结点执行转移贸易值的国家会将它们的贸易力集合起来牵引贸易值往下游流动。贸易输出(即流向下游的贸易值)的计算方式如下

等同于

在这种情况下,所有执行转移贸易值的国家会组团与在当前节点收集贸易值的国家竞争。

引导贸易值流向

每个派遣了Merchants.png商人团执行贸易转移的国家都会选择一个下游节点,并将输出的贸易值导向这个这个下游节点(玩家通过贸易地图模式来完成这一系列操作)。所有将贸易值导向同一个下游节点的国家会组团与将贸易值导向其它下游节点的国家和在当前节点执行收集贸易值的国家竞争。导向特定下游节点的贸易值的计算方式如下

Trade node window and trade map mode. The tooltip (on the steering button) lists countries steering in each direction, their trade power used to steer and trade steering bonus, and the percentage of power used to steer in each direction. Notice the trade power listed in the window for Lithuania, Teutonic Order and Sweden, which is used to pull trade forward, and their power listed in the tootip, which is used for steering and is higher due to their trade steering bonuses.

在这个等式中,“修正后的贸易力”指的是该国的贸易力乘以1+该国的Trade steering.png贸易导向修正。如果这个等式中的分母为零(比如没有一个国家派遣商人到这个节点执行贸易转移),这个公式变为

.

换句话说,在没人控制贸易流向的情况下,贸易输出会被均分给所有下游节点。

这个等式在游戏中产生的重要影响如下:

  • 没有派遣商人团引导贸易流向的国家在决定贸易值流向的问题上没有任何影响力。它们只能影响有多少贸易值从当前节点输出到下游。
  • 如果导向特定节点的贸易力之和为零,那么流向该节点的贸易值也为零(除非导向所有节点的贸易力之和都为零)。换句话说,如果在某个节点有商人团在引导贸易流向,但有个下游节点却没有任何商人团将贸易导向它,那么不会有任何贸易值流向这个节点。如果在某个节点只有一个国家的商人团在引导贸易流向,那么该节点的所有贸易输出都会流向该国所选择的下游节点,不论该国在该节点中的贸易力占比有多小。
复数商人加成
Three merchants steering from Krakow to Baltic Sea, each with a merchant bonus. This tooltip is on the outgoing node, but not the steering button.

In addition to steering outgoing trade value through a particular outgoing link, each merchant applies a boost to the trade value on that link—that is, the steered trade value increases by a percentage as it passes between the two nodes, so that the incoming trade value of the downstream node is larger than the corresponding outgoing trade value of the upstream node. This affects all trade on that link, not just the merchant's country, so multiple merchants can boost trade on the same link. The total boost is:

商人数量 加成增幅 加成累计
0 0.0% 0.0%
1 +5.0% +5.0%
2 +2.5% +7.5%
3 +1.6% +9.1%
4 +1.2% +10.3%
5 +1.0% +11.3%

多于五个商人不会提供更多的加成。单个商人的加成增幅受 trade steering 影响:举例来说,如果一个国家有+20%的 trading steering 加成,那么该商人的加成增幅就会由+5%增加到+6%。但由于当前游戏中并没有一个排序系统,所以复数商人加成并不一定处于效益最大化的状态。

Transfers from traders downstream

Ming has 14.1 provincial trade power in the Yumen node. They don't collect here or anywhere downstream, but 20% of their unmodified power transfers to the incoming node Beijing. You see this blue left-facing arrow in nodes not upstream of any collection, but the transfer happens also in collecting and transferring nodes.

Any nation that has at least 10 provincial trade power in the node enjoys the propagation of that power upstream. An amount equivalent to 20% of the nation's provincial trade power is added to the total trade power of that nation in every immediate upstream node, where it is denoted as transfers from traders downstream. Global trade power modifiers do not apply to the amount considered for propagation, but are applied in the upstream node instead.[2]

贸易公司

主条目:贸易公司

属于贸易公司的省份会获得+100%的贸易力加成。游戏中总共存在15个贸易区域,均位于亚洲和非洲。[3]对一个国家来说,所有有建立贸易公司的节点都被划分为本土节点,因此这些节点的贸易力不受Overextension.png过度扩张影响。

保护贸易

一个国家可以通过往沿海贸易节点派遣轻帆船执行保护贸易任务来增加该国在这个节点中的贸易力。 Ships can only be sent to protect trade in coastal nodes where the country already has trade power or a merchant. Each light ship increases trade power in the trade node in which they are protecting trade, the amount depending on how advanced it is; higher technology unlocks better light ships. Having the ships out of port for the Protect Trade mission costs Sailors.png −1 sailor per ship per month.


Diplomatic tech.png 名称 Trade power.png Hull.png Icon ship cannons.png Icon ship speed.png 描述
2 三桅帆船 2 8 10 10 三桅帆船是一种小型帆船,原本用于贸易。为了适应战斗,小而快的三桅帆船被更庞大的卡拉克大帆船取代。
9 卡拉维尔帆船 2.5 10 13 10 卡拉维尔帆船是一种小型的高机动性船只,可以精准的进行长途航行。虽然其设计是五花八门,但卡拉维尔帆船都配有一个前帆、一个方形主帆和三角后帆。该船船身较小,可配武器的数量因此受限制,但这也意味着这种轻便的船可以探索浅的近海水域及河口.瓦斯科·达·伽马、卡伯特、哥伦布和麦哲伦在他们15世纪末16世纪初的航行中便使用了卡拉维尔帆船。
15 早期三桅战舰 3 12 15 10 随着海外贸易的日益增加,保驾护航的快速护卫舰需求激增,早期护卫舰应运而生。它们是更为精悍的战舰,只有一个载炮台,在危险水域保护船只免受海盗侵害。
19 三桅战舰 3.5 16 20 10 随着时间的推移,护卫舰也进行了改进。它得以增大、全副武装,有时配有两个载炮台。这种护卫舰融合了速度与火力,这就意味着它能摆脱装有更多炮的战舰,也能摆脱任何更高速的舰船。英格兰联邦在17世纪50年代组建的舰队中绝大多数是护卫舰。
23 重型三桅战舰 4 20 25 10 这种双层甲板的船只一般装备有40门炮。
26 大型三桅战舰 5 24 30 10 一个更大型的三桅战舰,可以携带更多火炮。

No ideas or policies currently affect ship trade power.

补给距离

一个国家只能向在补给距离内且已有贸易力贸易节点派遣轻帆船。即使在达到Diplomatic tech.png22级外交科技海军损耗不再产生影响后,补给距离仍会限制轻帆船执行任务的距离。如果一个节点在一个国家的贸易距离之内,那么该国便可通过先派遣一个商人到该节点,然后派遣轻帆船执行保护贸易的方式来提高该国对这个贸易节点的影响力。一个行之有效的将玩家控制国家的补给距离扩张到一个远方的贸易节点的策略是从该节点附近的国家处获取舰队停靠权

其他贸易力来源

  • 有商人部署:往一个节点派遣商人可以增加2点在该节点的贸易力。
  • 贸易本埠所在地:一个国家在它贸易本埠所在的节点获得额外的5点贸易力。
  • 殖民领会将它的50%贸易力贡献给它的宗主国。
  • With Mare Nostrum.png Mare Nostrum, members of a Trade league.png trade league:
    • provide 50% of their trade power to the leader of the league
    • provide an extra Trade steering.png +0.025% trade steering to the leader of the league (cumulative with the bonus from other members)
    • get an additional Ship trade power.png +20% ship trade power.
  • Other nations can be persuaded (through diplomacy) or forced (through war) to enter into a Transfer Trade Power relation, which does not count towards the diplomatic relations limit. This transfers one country's trade power to another: a transfer enforced in a truce transfers 50%, while a diplomatically arranged transfer can transfer any amount from zero to 50%. Personal unions and vassals do not transfer trade power to their suzerain.
  • With Common Sense.png Common Sense, countries that have vassals or marches have a subject interaction for them to divert trade, which transfers 100% of their vassal's trade power, at a cost of Liberty desire.png +30% liberty desire.

商人团

商人团是一种通过转移贸易值或收集贸易值来改变游戏中贸易系统默认表现的使者。商人团必须进驻一个贸易节点后才能开展他们的工作,可到达的节点受贸易距离限制。贸易距离会随着外交科技理念组国家理念的变化而变化。

Trade with no merchant

In the absence of merchants:

  • In the country's home node, the country will collect trade.
  • In non-home nodes that are not upstream from any nodes where the country is collecting trade, their trade power does not affect the flow of trade. It still propagates upstream if the country has at least 10 provincial trade power.
  • In all other nodes, trade power is used to pull trade forward, increasing the share of trade value transferred. There is no influence on the direction of trade, only the amount transferred.

商人团行动

Merchants can be sent to a trade node to perform one of two missions (as denoted in game interface):

  • Collect from Trade: Use the country's trade power to retain trade in the node, and turn it into Gold Icon.png income. This gives a bonus +10% trade efficiency in that node.
    • In the country's home node, this also gives a bonus Trade power.png +2 trade power.
    • In other nodes, this gives a multiplicative penalty of Trade power.png −50% trade power.[1]
  • Transfer Trade Power: Use the country's trade power to pull trade forward in the trade network, and simultaneously to influence trade to flow preferentially into one of the downstream nodes (see § Steering trade above). The player can choose the direction to steer trade in using the trade map mode. (The name of this mission is a misnomer, as it is trade value that is being steered, not trade power.)

Although merchants steering provide no additional trade power on their own, they allow the country to send light ships to protect trade where they otherwise could not due to lacking trade power.

重商主义提供Trade power.png省份贸易力加成,每1%的重商主义提供2%的加成。[4] 但重商主义同时也会提升殖民领的独立欲望 (独立欲望提升额度正比于重商主义,100%的重商主义提升25%的独立欲望).

大部分国家的重商主义初始值是Mercantilism.png10%,但有些国家的初始值是Mercantilism.png25%。以下列出所有初始值为25%的国家:

特定的事件、决策和任务会给予永久的重商主义变化,以下为几个例子:

Trade steering

Trade steering.png Trade steering is applied as a multiplicative bonus to trade power used for steering when determining which outgoing node trade is steered to. It does not increase the share of trade value pulled forward.

Trade steering is increased by certain ideas and policies.

禁运

禁运是一种利用国家的贸易力来对抗敌对国家的手段,该手段能减少敌对国家在共有贸易节点中的贸易力。禁运作为一个可选项会出现在国家总览的外交标签页中。在国家总览的贸易标签页中,游戏系统会以国家图标的方式来显示玩家所控制的国家对哪些国家实施禁运,以及哪些国家对玩家所控制的国家实施禁运。将鼠标停留在这些国家图标上时,系统会详细列出在各个共有贸易节点中禁运造成的贸易力惩罚。

对一个国家实施禁运有如下效果:[5]

  • 被禁运的一方会在所有共有节点中承受贸易力惩罚。贸易力惩罚的大小等于主动禁运一方在共有节点中所有贸易力中所占份额的一半(在发动禁运之前)。 禁运惩罚和其他修正之间是累成关系。
  • The defending country's opinion of the attacking country is modified by −15. The defender also gains a Trade Dispute casus belli against the attacker unless the embargo is mutual.
  • The attacking country's trade efficiency suffers a −5% penalty unless the defender is a rival.
  • 禁运占用外交关系限额。
  • The attacking country gains up to Power Projection.png +10 power projection if the target is a rival, the amount depending on how severely the embargo affects the target's trade.

禁运效率可通过以下手段增加:

私掠

主条目:Naval warfare#Privateering

Any fleet that contains light ships can be sent on a privateering mission to any trade node within trade range. The fleet will hoist the Jolly Roger and add the trade power of its light ships (plus a bonus) to a dummy "pirate" nation in the node, thus reducing the trade power share of everyone in the node – including their controller, though a portion of the trade value lost this way is returned to the controller, listed in accounts as "spoils of war". This effectively behaves as though they are collecting. Unlike protecting trade, privateers can be sent to nodes a nation has no power in, making it a way of weakening the nation's enemies or gaining revenue from nodes it can't touch otherwise. Privateering a rival's trade generates power projection.

追捕海盗

主条目:Naval warfare#Hunt pirates

This mission is available to fleets which contain at least one ship that isn't a transport. Fleets containing heavy ships or light ships may hunt pirates in any non-inland trade node; however, fleets containing only galleys (as well as fleets which are a mixture of galleys and transports) can only hunt pirates in nodes where all nearby sea provinces are inland seas.

Pirate-hunting fleets reduce the trade power taken by the dummy "pirates" nation in the chosen trade node by reducing their privateer efficiency. They do not actually damage or take damage from any ships.
