永續發展是發展過程中一個不容忽視的重要課題。但在海地，永續發展顯然並沒有被適當地計畫在發展過程中。人口的成長導致經濟資源分配失衡，近期研究顯示迅速且未經妥善規劃的都市化是威脅海地社經的重大因素，因此我們可以發現都市化和發展之間存在著非常複雜的關係。此研究透過迴歸分析及比較社會科學方法來檢視海地的都市化和經濟發展對其永續發展的影響。此分析建立在全球地理範圍上，時間範圍為過去25年。研究結果顯示過去25年都市化的程度有劇烈的成長。資料同時也支持都市化程度跟人類發展指數(Human Development) 及人均國內生產總值 (GDP per capita) 有很大的相關。在海地發生了非常劇烈的人口增長，但生活水平卻沒有相對提升來因應此變化。因此，本研究結論顯示國家無法透過增加都市化的程度來提升人民福祉，尤其政府所主導的都市化更沒辦法達成此目標。再者，研究結果也顯示當經濟發展呈算術成長、人口發展卻呈指數或幾何成長時，永續發展的目標是無法達成的。;Sustainable development remains one of the most crucial development concepts nowadays. Signs of progress towards its achievement in Haiti seem to be not correlated. And also, the population growth is not parallel to the economic resources of the country. Recent studies identify rapid and unplanned urbanization as a major threat. So, there is a perplexing relationship between urbanization and development. This study analyzes the scenario (Urbanization and Development) and their implication on sustainable development in Haiti, using the regression analysis method and the comparative social science approach. The analysis has been conducted on a global geographic scale, while the time scale of the study covers the last 25 years. Results show that urbanization levels have changed extensively during this period. Data findings support the general idea of close link between urbanization levels and Human Development (HD) as well as a significant evidence correlation with the Gross Domestic Product (GDP) per capita at all levels. Moreover, an unprecedented demographic disaster was identified at the country level but with almost no improvement of the living conditions of the population. Hence, this study concludes that a given country cannot obtain the expected human wellbeing improvement from accelerated urbanization, especially if it takes the form of government-led urbanization. In addition, the sustainable development goals cannot be achieved in a country where the economic growth is in arithmetic way while the population growth is in exponential or geometric way.
