《Foundation》的经济建立在税收与贸易体系之上，居民晋升是核心驱动力。一个农奴每月交 1 金币，一个市民每月交 25 金币，同时消费推动高级产业的奢侈品。本指南涵盖完整的居民晋升路径、贸易路线精通、纪念碑投资回报优化，以及从小村金库到中世纪金融巨头的经济扩张策略。

📈 Villager Promotion Pipeline

等级	Tax/Month	Needs	Unlocks	Promotion Strategy
👤 Serf	1 gold	Food (1 type), Water (well), Basic Shelter	Farming, Logging, Basic Labor	Keep 60% of population as serfs through mid-game. They're your labor backbone.
👤 Commoner	8 gold	Food (2 types), Clothing, Church access, Beer	Crafting, Smithing, Tailoring, Trade	Promote 20-30% to commoners. Each commoner needs 3× the goods of a serf — scale production first.
👤 Citizen	25 gold	Food (3 types), Tools, Jewelry, Decorated Housing, Entertainment	Advanced crafting, Monuments, Administration	Promote 10-20% to citizens. Each citizen = 25 serfs in tax revenue. But each citizen consumes luxury goods from 4+ production chains.

The 60-25-15 Rule

最优人口比例：60%农奴，25%平民，15%市民。200人城镇：120农奴(120金/月)，50平民(400金/月)，30市民(750金/月)=总计1270金/月。不要过度晋升——平民不种地，市民不劳动。晋升太多，劳动力会崩盘。

🚢 Trade Route Mastery

Trade Partner	Buys	Sells	Distance	策略
🏙️ Northburgh	Bread, Beer, Wheat	Tools, Iron Ore	Short	Your primary early-game partner. Export surplus bread. Import iron ore if you lack a local iron mine. Max mastery first.
🏙️ Kallio	Jewelry, Stained Glass, Gold	Marble, Quartz	Long	Late-game luxury trade. Jewelry sells for 50 gold/unit but requires citizen-tier workers. Build this route after your first 20 citizens.
🏙️ Monastic Orders	Herbs, Honey, Wine	Relics, Manuscripts	Medium	Niche trade. Herbs from your monastery garden sell for 15 gold/unit. Build a monastery by year 3 for this income stream.
🏙️ Coastal Traders	Fish, Salt, Rope	Exotic Goods, Spices	Short	If you spawned on a coast. Fish is infinite resource. Salt preserves food. Consistent income if coastal.

Trade Mastery Levels

每条贸易路线有精通等级(1-10)。等级越高=买卖价格越好+马车越快。10级精通的面包路线卖18金，1级的只卖12金——50%的收入差距。永远不要在精通只有2级时把商队分散到5条路线。先集中把3条路线升到7+级再扩张。精通加成会随贸易量滚动增长。

🏛️ Monument ROI Optimization

纪念碑	Gold Cost (Resources)	Monthly Return	Payback Period	优先级
⛪ Village Church	~200 gold (100 stone + 50 planks)	Prevents emigration events (saves 2-5 villagers/year = 10-25 gold/mo equivalent)	~1 year	1st
🏰 Lord's Manor	~500 gold (200 stone + 100 planks + 50 iron)	+5 gold × citizen count/month. 10 citizens = +50/mo.	~2 years	2nd
⛲ Grand Fountain	~300 gold (150 stone + 50 marble)	Houses promote 40% faster = more commoners/citizens = more tax. Soft ROI.	~3 years	3rd
🏛️ Cathedral	~3,000 gold (500 stone + 200 marble + 100 glass + 50 gold)	+20 population (pilgrims) + max faith + tax from 20 new villagers.	~5 years	Endgame

The Real ROI of the Church

乡村教堂不直接产生金币。但没有它的话，信仰低于30%时可能触发「大规模出逃」事件，5-10个居民永久离开。补充这些居民需要2+游戏年的移民。教堂能阻止这一切。最晚第2年建。

💰 Gold Management & Treasury

Gold Reserve Minimum

Keep 500 gold minimum in treasury at all times. Below 200 gold, you can't pay army wages — soldiers desert. Below 100 gold, trade stalls close — your economy seizes. Gold below 500 = emergency mode: cancel all construction, sell excess goods at any price.

Tax Rate Optimization

Default tax = 10%. At 15%, commoners complain (−5% happiness). At 20%, citizens protest (−10% happiness, possible riots). Never exceed 12% tax. Instead, grow your tax base by promoting villagers. 10 more citizens at 10% tax = 250 gold/mo. Raising tax to 12% on 30 citizens = +18 gold/mo. Promotion always beats taxation.

Army Cost Management

Each soldier costs 15 gold/month in wages + 5 gold/month in equipment maintenance. 10 soldiers = 200 gold/mo. Only maintain a standing army if you need it. During peace, disband half your soldiers. They'll return to labor and generate tax income. Remobilize when raids threaten.

Import Substitution

If you're importing iron tools at 25 gold/unit and using 10/month, that's 250 gold/mo leaving your economy. Build an iron mine + smelter + blacksmith instead. The buildings cost ~400 gold one-time and produce tools at material cost (~5 gold/unit). Payback period: 2 months. After that, 245 gold/mo stays in your treasury.

FAQ

什么时候建领主庄园？+

有了 15 个平民之后。庄园解锁税收，税收支撑一切。没有庄园，你的唯一收入来源是基础贸易——80 人口左右就会碰到金币瓶颈。

金币总是不够用怎么办？+

三个解决办法：(1) 检查进口账单——有没有东西是你自己能生产却在进口的？(2) 把需求已满足的农奴晋升为平民。(3) 把贸易精通集中在 2 条路线，不要分散到 5 条。

最好的奢侈品是什么？+

珠宝（50 金币/单位出口）但需要市民。第二：彩色玻璃（40-55 金币/单位）来自采砂场（无限资源）+ 石英。第三：铁制工具（18-25 金币/单位）——最可靠的中期出口品，产业链最简单。
