這篇論文檢驗了儲蓄是否會影響通貨膨脹與貧富差距之間的關係。研究期間為 1970 年至 2020 年的年資料，選取了已開發國家和開發中國家的樣本進行分析，透過固定效果模型以及 SGMM 模型，探討在不同的經濟體下，當通貨膨脹發生時，儲蓄會加劇還是減緩通膨對貧富差距的影響。另外，本研究還使用了穩健性分析。

結果顯示，通膨與貧富差距在全樣本下呈顯著的擴大作用。此外，儲蓄的上升也會顯著的擴大貧富差距。但當分別分析已開發國家與開發中國家時，儲蓄的影響並不顯著。具體而言，已開發國家展現出儲蓄在通膨時期具有緩解貧富差距的潛力，而在開發中國家中，通膨與儲蓄的交互作用對貧富差距並未呈現顯著影響。整體來看，全樣本下的證據表明，通膨和儲蓄的上升會加劇貧富差距，但通膨與儲蓄的交互效果則有助於降低貧富差距。然而，不同經濟體中的影響機制存在顯著差異，需根據各自的經濟特性進一步探索。

This thesis explores the relationship between savings, inflation, and income inequality using panel data from 1970 to 2020, encompassing both developed and developing countries. Employing fixed-effects models and the System Generalized Method of Moments (SGMM), the research examines how savings influence the impact of inflation on incom inequality across different economic contexts. Robust statistical techniques were utilized to validate the findings.

The results reveal significant evidence of inflation’s role in exacerbating income inequality across the full sample. Moreover, increases in savings were found to significantly widen income disparities. However,when analyzing developed and developing countries separately, the impact of savings becomes not significant. Specifically, developed countries demonstrated potential for savings to mitigate income inequality during inflationary periods, while in developing countries, the interaction between inflation and savings showed no statistically significant effect on income inequality. Overall, the full-sample analysis indicates that both inflation and increased savings tend to amplify income disparities. Interestingly, the interaction between inflation and savings may help reduce income inequality. However, the underlying mechanisms differ substantially across economic contexts, suggesting the need for further investigation tailored to specific economic characteristics of different countries.
