大量學術文獻指出氣候變化是毫不含糊地由持續增加的人為溫室氣體排放所造成。其中，二氧化碳排放（碳排放）是最為重要的溫室氣體排放。碳排放和經濟發展之間的密切關係亦受到廣泛肯定。碳排放和收入之間的關係引起了研究人員的極大興趣。學者們對該關係的環境庫茲涅茨曲線（一個倒U形曲線）的有效性持有不同的觀點，該曲線之有效性的討論可以分為兩部分，即時間和空間（國家）的尺度。 / 在這項研究中，首先以描述性統計研究碳排放量的變化，其中包括排放總量，人均排放量和碳強度三個指標。然後，透過雙對數和二次雙對數回歸模型進一步研究這三項指標和各經濟發展指標的關係（經濟發展指標包括總量和人均國內生產總值，貿易值和產業值）。結果指出國內生產總值可以很好地解釋碳排放之變化。根據1970年到2007年的數據，排放總量和國內生產總值總量在雙對數回歸模型中呈現顯著的線性關係。同樣在雙對數回歸模型中，人均排放量和人均國內生產總值之間的關係則從顯著線性變成顯著二次（倒U形曲線），從而支持環境庫茲涅茨曲線理論。碳強度和人均國內生產總值之間的關係是顯著的倒U形曲線。所有研究國家的回歸結果指出，發達國家在經濟增長的同時，已經減少排放總量及人均量，而發展中國家沒有減少。大多數發達國家在碳強度和人均國內生產總值的關係上呈現顯著的負相關，而發展中國家在碳強度和人均國內生產總值之間的關係上比例平均。在一般情況下，其他因素如貿易值和產業值解釋碳排放變化之能力較國內生產總值差。較特別的結果是由於製造、礦業和公用事業產業值屬於高碳密集性，該產業能很好地解釋碳排放的變化，所以為該產業的度身訂造之減排控制是必要的。 / 進一步說，發展中國家之間的差異仍然很大。透過層次聚類法，所有國家基於排放水平可分成11個類。其中，第11類主要包括發達國家，擁有極高的排放總量，非常高的人均排放量和中等的碳強度。與此同時，第4類主要包括發展中國家，亦有非常高的總排放量，中等的人均排放量和極高的碳強度。美國和中國，分別為第11類和第4類的案例研究，這兩國能有效地幫助了解碳排放和經濟發展之相互關係。其他集群則代表不同的經濟發展階段。聚類分析的結果可作為未來國際氣候變化政策建設的參考。 / Wealth of scholarly reviewed literatures indicates that climate change is unequivocally caused by the continual increase in anthropogenic greenhouse gases (GHGs) emissions. Carbon dioxide emissions remain to be of upmost importance among all GHGs emissions. It is widely accepted that close relationship between carbon dioxide emissions and economic development exists. The relationship between carbon dioxide emissions and income, in particular, has aroused much research interests. Researchers have polarizing views on the validity of Environmental Kuznets Curve (EKC), an inverted U-shaped curve of that relationship. The ground of argumentation for the validity of EKC can be also divided into two parts, namely temporal and spatial (national) extents. / In this research, variations in three indicators of carbon dioxide emissions, including total emissions, per capita emissions and carbon intensity (CI), are firstly examined by descriptive statistics. Next, double-log and quadratic double-log regression models are employed to study the relationship between these three indicators and indicators of economic development (including the total and per capita GDP, trade values and sectoral values). Results show that GDP has high explanatory power for the large variation of emissions. By using the data from 1970 to 2007, the relationship between total emissions and total GDP is significantly linear in double-log regression models. The relationship between per capita emissions and per capita GDP has changed from linear to quadratic (inverted U-shaped), which supports the EKC. The relationship between CI and per capita GDP is significant in an inverted U-shaped curve. Regression results in each country indicate that developed countries have reduced total and per capita emissions in parallel with economic growth while developing countries have not. Majority of developed countries have negative relationship between CI and per capita GDP; whereas their counterparts have even proportion in the relationships. Other explanatory factors, like trade values and sectoral values, in general, have lower explanatory power than GDP. Surprisingly, results indicated that manufacturing, mining and utility (MMU) sector yields very high explanatory power for the variation of carbon dioxide emissions due to the sector’s high carbon-intensive nature. Tailor-made control on this sector is necessary for emissions abatement. / Furthermore, as the variation within developing countries is still large, countries are classified into clusters on the basis of their levels of emissions by Hierarchical Cluster Analysis. Eleven clusters are formed. Among all, cluster 11, comprised of mostly developed countries, yields extremely high total emissions, very high per capita emissions and medium CI. Meanwhile, cluster 4, made of mostly developing countries, have very high total emissions, medium per capita emissions and extremely high CI. The USA and China, case studies of clusters 11 and 4 respectively, have provided insight for the interactive relationship between emissions and economic development. Remaining clusters represent different stages of economic development. The results of the clustering can serve as a reference for the construction of future climate change policy. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Wong, Wai Fung. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 273-280). / Electronic reproduction.
