中國在香港的一國兩制以高度自治為治理基礎,香港在1997回歸中國後已過了18個年頭,中國政府當初在中英聯合聲明中所給予香港的承諾如：高度自治,資本主義,以及人權自由,然而,這些承諾在今日的香港發展的如何為此論文的研究目的。研究方法採取文獻分析法以及次級資料分析,並且運用官方文件和香港大學的民意調查來做為研究基礎。研究結果發現,香港的高度自治尤其是在民主發展的進程,中國政府依然扮演著重要的角色,另一方面,除了新聞自由在近年來備受波及外其他方面的人權自由皆沒有明顯受侵害的趨勢。香港繁榮在回歸之後雖然幾度陷入全球蕭條的影響但在和中國快速經濟整合的背景下,香港的經濟得以維持在一定水準,但貧富差距等問題造成香港政府及社會的隱憂。 / This research is an attempt to conduct a preliminary assessment of one-country two systems in Hong Kong since the handover of sovereignty from British government back to China in 1997, particularly on the aspects of high degree of autonomy and economic performance.
