Public Finance as Intergenerational Contract Enforcement
公共财政作为代际契约的执行机制
-
National budgets are not mere accounting summaries but legally encoded commitments across temporal boundaries—between current taxpayers, future beneficiaries, and unborn populations bearing ecological or debt legacies.国家预算不仅是会计汇总，更是跨越时间界限的法律承诺——连接当前纳税人、未来受益者以及将承受生态或债务遗产的未出生人群。
-
Fiscal rules like debt brakes or sustainability reserves aim to formalize intergenerational equity, yet their effectiveness depends on independent monitoring and non-partisan enforcement bodies.债务刹车或可持续性储备等财政规则旨在制度化代际公平，但其有效性取决于独立监督和无党派执法机构。
-
Pension fund solvency assessments, climate liability provisioning, and infrastructure depreciation schedules all reflect implicit valuations of future welfare relative to present consumption.养老金基金偿付能力评估、气候责任拨备以及基础设施折旧安排，均隐含着对未来福利与当前消费的相对价值判断。

-
Intergenerational accounting frameworks—tracking assets, liabilities, and demographic pressures across 50-year horizons—reveal structural imbalances masked by annual budget surpluses.代际会计框架——追踪长达50年跨度内的资产、负债及人口结构压力——揭示了年度预算盈余所掩盖的结构性失衡。
-
Digital fiscal ledgers, with immutable audit trails and real-time accrual accounting, make intertemporal obligations more visible and harder to defer through accounting sleight-of-hand.数字财政账本凭借不可篡改的审计轨迹和实时权责发生制会计，使跨期义务更透明，更难通过会计技巧延后履行。
-
Yet enforcing such contracts remains politically fraught: democratically elected officials face incentives to optimize for near-term electoral cycles rather than multi-decade equilibria.然而此类契约的执行仍充满政治阻力：民选官员往往倾向于优化短期选举周期，而非多十年尺度的均衡。
-
Intergenerational justice requires not just fiscal discipline but institutional innovations—like citizen assemblies with binding advisory powers on long-term investment priorities.代际正义不仅需要财政纪律，还需制度创新——例如赋予公民大会对长期投资优先事项的具约束力咨询权。
-
Public finance thus operates as society’s primary mechanism for translating ethical commitments about fairness across time into concrete resource allocations and legal obligations.公共财政因而成为社会将跨时间公平伦理承诺转化为具体资源配置与法律义务的核心机制。
-
Its integrity hinges not on balancing annual books but on sustaining credible, adaptive, and democratically anchored stewardship across generations.其公信力不在于年度账目平衡，而在于维系一种可信、可调适且植根民主的跨代际治理。
