在全球自然灾害频发和贫困长期且不均衡展布的背景下,灾害风险与贫困的联结成为学术界和利益相关者关注的焦点。基于自然灾害风险管理和社会-生态韧性评估的基本原理,系统论述了灾害致贫和贫困致险的作用机理与驱动路径,这种互相关效应称为灾害风险-贫困的“羁绊”;基于中国31个省（自治区、市）2010—2019年的面板数据,运用计量经济学回归分析方法,以证实减轻灾害风险和扶贫脱贫在省域尺度上存在双向加持的作用。结果表明：（1） 较高的致灾因子危险性、承灾体暴露性和脆弱性及复杂的灾害风险情景引发了人员伤亡、资产破坏和经济损失等多重负面影响,最终导致和加剧了经济、机会、能力和文化的多维度贫困;贫困群体农业生计和家庭资产的高暴露性和低韧性放大和累积了灾害风险。（2） 中国在脱贫攻坚和全面建设小康社会的进程中,减灾扶贫和脱贫降险的循环效应显著,籍此带来了乡村振兴、治理现代化等战略的属性加持。（3） 贫困致险的机制较为隐性且主要显现于广布型灾害风险情景,对其无视或轻视可能带来投资减灾失效、学科范式陷阱和不可持续发展等诸多后果。研究结果可为中国的减灾和扶贫协同发展提供理论依据和现实证据,并为贯彻落实经济、政治、文化、社会和生态文明建设“五位一体”战略,实现“双碳”目标和应对全球气候变化提供智力支撑。

In order to clarify the disaster risk-poverty nexus and evaluate the two-way correlation effects related to poverty caused by disasters and risk caused by poverty, this paper takes the “fetter” of disaster risk and poverty as the study object. This work aims to integrate disaster risk reduction (DRR) and poverty alleviation. Using the econometrics hypothesis test, this work uses regression analyses on the data from 31 provinces in China from 2010 to 2019 to identify the positive effects of investment in poverty alleviation on DRR. The research shows that: (1) High disaster risk produces huge casualties and asset destruction, resulting in economic poverty. High disaster risk leads to long term poverty and relative poverty by eroding agricultural livelihoods and destroying development capacity. The high exposure to disaster risk, vulnerability, low resilience, and low adaptive capacity of the poor lead to the continuous amplification and accumulation of disaster risks. (2) The disaster risk-poverty nexus exists on many scales, including the scale of province, city, and family. Such an effect on the scale of the country and continent is not clear. In the process of building a economically well-off society and eradicating poverty, China has undertaken considerable risk control and mitigation. (3) The causal relationship between disaster risk and poverty (closed loop or cyclic relationship between disaster and poverty) is not a “natural phenomenon” but a historical function of the mainstream economic social paradigm. It is a result of the capital economic cycle. If the economic and social operation mode does not change, the connection between disaster risk and poverty will not disappear. At the same time, economic globalization, inequality, disordered urbanization, poor governance, damage to the ecological environment, and climate change have exacerbated the effect of disaster risk-poverty fetters. Faced with this dilemma, a multidisciplinary approach and bold creative thinking are necessary. Ignoring or not sufficiently addressing this topic will weaken the global DRR effort and impose a paradigm trap to disaster risk science. This study intends to provide a theoretical basis and evidence for the coordinated development of DRR and poverty alleviation in China. This work also provides intellectual support for the implementation of the “five in one” strategy for the construction of economic, political, cultural, social, and ecological civilization and the realization of the “double carbon” goal and the response to global climate change.
