唐斯的中位选民定理如何解释政党在选举中向「中间」靠拢？
How does Downs's median voter theorem explain why parties converge toward the 'center' in elections?
唐斯在 1957 年《民主的经济理论》中模型化：在单维议题与多数决下，为争取占多数的中间选民，相互竞争的两党会把政见移到选民偏好的中点。该定理预言选举趋同，却也因现实多维议题而受限。
In 'An Economic Theory of Democracy' (1957), Downs modeled that under a single left-right axis and majority rule, two competing parties move their platforms toward the median voter to win the majority. The theorem predicts electoral convergence, though it is limited by real-world multi-dimensional issues.

什么是“否决玩家”？
What is a "veto player"?
否决玩家理论指凡能单方面阻止政策变更的行动者（如参议院、宪法法院、地方诸侯）构成制度约束。否决玩家越多，政策越难改变、稳定性越高但改革越难。它用于比较各国制度刚性。
Veto-player theory says any actor able to unilaterally block policy change—a senate, constitutional court, regional baron—constitutes an institutional constraint. More veto players mean harder change: more stability but tougher reform. It compares institutional rigidity across countries.

如何用经济学解释腐败？
How does economics explain corruption?
经济学把腐败视为官员用公共权力换取私利的“寻租”，受查处概率、薪酬与垄断权力影响。低薪、强管制与弱法治会抬高其净收益。降低它需提高透明度、薪酬与问责。
Economics views corruption as officials' rent-seeking by trading public power for private gain, shaped by detection probability, pay, and monopoly power. Low pay, heavy regulation, and weak rule of law raise its net payoff. Reducing it needs transparency, pay, and accountability.

什么是“投票悖论”（孔多塞悖论）？
What is the voting paradox (Condorcet paradox)?
孔多塞悖论指在多选项多数决下，集体偏好可能循环（A胜B、B胜C、C胜A），从而不存在稳定“多数意志”。它揭示民主聚合个人偏好未必产出一致结果。排序投票等规则试图缓解。
The Condorcet paradox shows that under majority rule with three or more options, group preferences can cycle (A beats B, B beats C, C beats A), so no stable “will of the majority” exists. It reveals democracy may not yield consistent outcomes from individual preferences. Ranked-choice voting tries to mitigate it.

阿罗的「不可能定理」揭示了集体决策什么样的根本困境？
What fundamental dilemma of collective decision-making does Arrow's 'impossibility theorem' reveal?
阿罗在 1951 年证明：只要备选超过两个，任何同时满足「无限制域、一致同意、无关选项独立、非独裁」的投票规则都不可能存在。它说明把个人偏好「加总」成一致社会选择存在不可克服的逻辑障碍。
Arrow proved in 1951 that with more than two options, no voting rule can simultaneously satisfy unrestricted domain, unanimity, independence of irrelevant alternatives, and non-dictatorship. It shows an unavoidable logical barrier to aggregating individual preferences into a consistent social choice.

杜瓦杰定律如何解释选举与政党体系？
How does Duverger's law explain elections and party systems?
杜瓦杰定律指出：单一选区相对多数制倾向形成两党制，而比例代表制倾向多党制。因前者让小党选票“浪费”、选民策略性转向大党。它揭示制度规则塑造政治格局。
Duverger's law states that single-member plurality systems tend toward two parties, while proportional representation tends toward multiparty systems—because the former wastes small-party votes and pushes strategic voting to big parties. It shows rules shape political landscapes.

什么是“委托-代理”问题？
What is the principal-agent problem?
委托-代理问题指委托人（如股东）把任务交给代理人（如经理），因目标不一致且信息不对称，代理人可能谋私而损害委托人。公司治理、官场代理皆如此。解决靠激励相容、监督与透明。
The principal-agent problem arises when a principal (e.g., shareholders) delegates to an agent (e.g., managers) whose goals differ and who has private information, so the agent may act in self-interest. Corporate governance and bureaucracy both face it. Remedies are incentive alignment, monitoring, and transparency.

什么是“软法”？

什么是“政策俘获”？
What is "regulatory capture"?
政策俘获指被监管行业通过游说、旋转门与信息优势，使监管机构转而服务其私利而非公众。它导致监管失效与不公平。强化独立性、公开听证可减缓俘获。
Regulatory capture is when the regulated industry, through lobbying, revolving doors, and information advantage, bends the agency to serve its private interest over the public's. It causes regulatory failure and unfairness. Independence and open hearings mitigate capture.

「新公共管理」运动主张用哪些市场式做法改革政府？
What market-style reforms does the 'New Public Management' movement advocate for government?
胡德在 1991 年概括的新公共管理，主张把竞争、绩效指标、分权与「顾客导向」引入政府，像经营企业一样提供公共服务。它在英美等国广泛推行，却也因「过度量化」与削弱公共价值而受到批评。
Hood summarized in 1991 a New Public Management that brings competition, performance metrics, decentralization, and a 'customer orientation' into government, running public services like a business. Widely adopted in the US and UK, it is also criticized for over-quantification and eroding public values.

什么是“政策反馈”？
What is "policy feedback"?
政策反馈指一项政策不仅应对问题，还会反过来塑造公众态度、利益集团与后续政治，形成路径。如社保制度培养依赖其的选民群体。它说明政策是政治变迁的因也是果。
Policy feedback means a policy not only addresses a problem but also reshapes public attitudes, interest groups, and later politics, creating path dependence. Social security, for instance, cultivates voter constituencies dependent on it. Policy is both cause and effect of political change.

什么是政治合法性？
What is political legitimacy?
合法性指民众内心认为统治“应当被服从”的程度，不单靠强制。它来自选举、传统、绩效或意识形态认同。合法性高的政权更稳定、治理成本更低。
Legitimacy is the degree to which people believe a rule “ought to be obeyed,” beyond mere coercion. It stems from elections, tradition, performance, or ideological consent. Regimes with high legitimacy are more stable and govern at lower cost.

What are the characteristics of bureaucracy?

政党制度有哪几种？
What types of party systems exist?
常见有一党制、两党制与多党制。两党制（如美国）往往政府更稳，多党制（如欧洲）更包容却易组阁难。制度设计深刻影响政策风格与代表性。
Common forms are one-party, two-party, and multi-party systems. Two-party systems (like the US) often yield stable government; multi-party systems (like Europe) are more inclusive but prone to coalition difficulty. Institutional design deeply shapes policy style and representation.

什么是治理绩效？
What is governance performance?
治理绩效指政府实际解决问题的能力，如经济增长、公共服务与危机应对，而非制度形式本身。有些国家形式民主但绩效不佳，说明制度需与能力配套。民众满意度常随绩效波动。
Governance performance is a government's actual problem-solving capacity—economic growth, public services, crisis response—not merely its institutional form. Some formally democratic states perform poorly, showing institutions need capacity. Public satisfaction often tracks performance.
