📚 Price and Output Decisions under Nationalisation and Privatisation | 国有化与私有化下的价格与产量决策

In A-Level Economics, the debate over nationalisation and privatisation focuses on how ownership changes the objectives of firms, which in turn alters price and output decisions in product markets. Nationalised firms often pursue social objectives, while privatised firms are assumed to prioritise profit. The result can be a significant difference in allocative efficiency, productive efficiency, and the distribution of welfare.

在 A-Level 经济学中，国有化与私有化的争论核心在于产权变化如何改变企业目标，进而影响产品市场的价格与产量决策。国有企业通常追求社会目标，而私有化企业被假定以利润为先。这种差异可能对配置效率、生产效率以及福利分配产生显著影响。

1. Ownership Models: Nationalisation vs Privatisation | 产权模式：国有化与私有化

Nationalisation is the acquisition of private-sector assets by the state, often to correct market failure, ensure universal access, or protect strategic industries. Examples include railways, water supply, and energy networks.

国有化是国家取得私营部门资产，目的通常是纠正市场失灵、确保普遍服务或保护战略性行业。例如铁路、供水、能源网络等。

Privatisation reverses this process by transferring state-owned enterprises to private shareholders. The main justification is that private ownership and competition improve efficiency, innovation, and consumer responsiveness.

私有化则通过将国有企业转让给私人股东来逆转这一过程。其主要理由是私有产权和竞争能够提高效率、创新和对消费者的响应能力。

2. Theoretical Price and Output under Nationalisation | 国有化下的理论价格与产量

If a nationalised firm is told to maximise social welfare, it should produce where price equals marginal cost (P = MC). This ensures that society values the last unit exactly as much as it costs to produce.

如果国有企业被要求实现社会福利最大化，它应在价格等于边际成本（P = MC）处生产。这确保社会对最后一单位商品的评价恰好等于其生产成本。

However, in industries with extensive economies of scale, marginal cost is below average cost. Setting P = MC creates a financial deficit
