第12期 · 全民基本收入可行吗

The concept of universal basic income — an unconditional cash payment distributed to every citizen regardless of employment status — has migrated from the fringes of economic theory to mainstream political discourse. Driven by anxieties over automation and persistent wealth inequality, proponents argue that UBI represents a necessary reimagining of the social contract. While I support the principle, I believe its universal implementation at this juncture would be premature without robust empirical evidence and sustainable funding mechanisms. Proponents marshal a compelling case. UBI would eliminate the poverty trap inherent in means-tested welfare systems, where earning additional income triggers the loss of benefits, effectively imposing punitive marginal tax rates on the poorest. Finland's two-year pilot programme reported improvements in psychological well-being and a modest increase in entrepreneurial activity, suggesting that financial security fosters risk-taking and innovation. Moreover, as artificial intelligence threatens to displace large segments of the workforce, UBI is framed as an inevitable adaptation rather than a utopian aspiration — a floor below which no citizen can fall. Yet the obstacles are formidable. The most immediate concern is fiscal sustainability: a meaningful UBI in a country such as the United Kingdom would cost hundreds of billions annually, necessitating either substantial tax increases, cuts to existing public services, or deficit spending that could destabilise the economy. Furthermore, universality — the very feature that makes UBI administratively elegant — also renders it regressive in practice, channelling funds to wealthy individuals who have no need of support. Critics also raise legitimate behavioural concerns: would guaranteed income erode the work ethic, or could it be squandered rather than invested in human capital? The evidence from pilot programmes, while encouraging, has been small-scale and short-term, leaving fundamental questions about long-term macroeconomic effects unanswered. In conclusion, while UBI holds genuine promise as a response to twenty-first-century economic challenges, a wholesale rollout would be irresponsible given the present state of knowledge. What is needed instead is a series of large-scale, long-term trials across diverse economic contexts, accompanied by rigorous evaluation. The ambition should be commended; the timing demands caution.
