香港財政赤字分析

綠皮書首章由劉洋教授撰寫,探討了香港的財政赤字問題。近年來,隨著香港的赤字水平創下歷史新高,更在發達經濟體中排名前列,財政赤字已成為香港特區面臨的一項嚴峻新挑戰。研究發現赤字中大部分源自結構性赤字,不能單靠經濟增長的被動方式來緩解,而需要主動調整財政政策。土地收入貢獻了相當比例的財政收入,但其波動也帶來了高風險,往往引發收入的不穩定,因而需要實行更審慎的風險管理。 展望未來,政府需要在緩解赤字與推行財政政策之間做出平衡,而政府已積極主動調整財政政策。另一方面,香港在多年來累積了充足的財政儲備,儘管近幾年有所下降,但現今儲備水平仍處世界前列,下行風險有限。此外,特區政府應當充分利用政府債券計劃的額度,為基礎設施建設投資籌募資金,同時確保不損害長期財政的可持續性,並藉此促進資本市場發展和人民幣國際化。

香港聯繫匯率制度損益評估

自1983年起,香港一直實施與美元掛的聯繫匯率制度(聯匯制度)。在這40年間,制度運行穩定,順利應對了多次重大挑戰,如1997至1998年的亞洲金融危機和2007至2008年的全球金融危機等。值此制度40周年之際,本文將探討在新的國際經濟形勢下聯匯制度的現狀與發展。基於最新國際經濟學研究成果,通過量化指標,分析不同匯率制度對香港的利弊。

港大研究指滙率與通脹關聯低

傳統市場理論認為,貨幣滙率是反映經濟強弱的晴雨表。不過,香港大學經管學院金融學助理教授劉洋的研究發現,滙率浮動與經濟狀況和通貨膨脹等相關性很低,反之與金融市場的流動性,以及政府施行政策是否穩定有更大關係。 流動性與政策更具影響力 劉洋接受訪問時指出,其研究發現滙率是隨機遊走
