投资于减少灾害风险对于实现可持续发展目标至关重要，因为自然灾害会造成经济和人员损失，从而阻碍可持续发展。为考虑对减少灾害风险进行投资，决策者需要了解根据灾害造成的损害和社会经济发展情况进行适当投资的规模。然而，审查减少灾害风险投资的实证研究数量有限，因为各国投资的数据集很少。本研究旨在提出与气候变化适应相结合的防洪投资融资途径。据我们所知，这项研究是第一次对投资和损害与各经济体社会经济发展之间的关系进行实证分析。运用多元回归模型分析了防洪投资与洪灾损失及其他社会经济发展的关系。投资数据是从亚洲主要洪灾国家的政府机构收集的。人们发现，更大的洪水破坏与更大的防洪预算有关。政府在重大灾害发生后开始增加预算，并随着人均GDP和人口密度的增加而进一步增加。为了进一步研究减少灾害风险方面的投资，需要建立预算数据集。
Investing in disaster risk reduction is crucial in achieving the Sustainable Development Goals since natural disasters can impede sustainable development by causing economic and human losses. To consider investment in disaster risk reduction, policymakers need information on appropriate scales of investment depending on disaster damage occurred and socioeconomic development. However, there is a limited number of empirical studies that examine investment in disaster risk reduction, since the dataset of investments across countries is rarely available. This study aims at proposing the approaches of financing investment in flood protection, which is integrated with climate change adaptation. To our knowledge, this study is the first empirical analysis on the relationship between investment and damage and socio-economic development across economies. A multiple regression model is applied to analyze the relationship between investment in flood protection and flood damage and other socio-economic development. Investment data were collected from government agencies in major flood-prone countries in Asia. It was found that greater flood damage is associated with a larger budget for flood protection. The governments start increasing budgets after major disasters happen and further increase them as GDP per capita and population density rise. To study investment in disaster risk reduction further, datasets of budgets need to be established.
