本文在非均衡框架下考察中国最优外汇储备数量特征并对持储动机进行静态和动态分解。结果发现:中国的实际和最优外汇储备量自2002年起陡增,但后者始终低于前者且二者缺口不断扩大;中国的最优外汇储备持有行为体现着交易性动机、预防性动机、重商主义动机和攀比动机,并受汇率因素影响;交易性动机和攀比动机对最优外汇储备持有行为的影响最大,预防性动机在2006年以后逐渐强化,重商主义动机和汇率因素的影响微弱;中国较低的储备缺口调整系数造成中国最优外汇储备量居高不下。外需拉动型的经济发展模式、强制结售汇制和汇率弹性不足则是导致储备缺口调整系数低下的重要原因。
本文在非均衡框架下攷察中國最優外彙儲備數量特徵併對持儲動機進行靜態和動態分解。結果髮現:中國的實際和最優外彙儲備量自2002年起陡增,但後者始終低于前者且二者缺口不斷擴大;中國的最優外彙儲備持有行為體現著交易性動機、預防性動機、重商主義動機和攀比動機,併受彙率因素影響;交易性動機和攀比動機對最優外彙儲備持有行為的影響最大,預防性動機在2006年以後逐漸彊化,重商主義動機和彙率因素的影響微弱;中國較低的儲備缺口調整繫數造成中國最優外彙儲備量居高不下。外需拉動型的經濟髮展模式、彊製結售彙製和彙率彈性不足則是導緻儲備缺口調整繫數低下的重要原因。

This paper explores the quantitative characteristics of China' s optimal foreign reserves under disequilibrium framework and then decomposes reserve hoarding motivations in static and dynamic model. We find that:China' s actual and optimal foreign reserves are surging since 2002 with the later far below the former and their gap extending; China's accumulation of optimal foreign exchange reserves reveals the presence of transaction motivation, precautionary motivation, mercantilism motivation, competitive motivation and the influence of exchange rate volatility. The transaction motivation and competitive motivation are of the largest influence, and the precautionary motivation is of upward trending since 2006, while the mercantilism motivation and exchange rate factor are of weak influence; The lower adjustment coefficient λ finally leads to China' s high optimal foreign reserves. Export - oriented economic development mode, compulsory foreign exchange settlement regime and lack of foreign exchange rate flexibility lead to the lower adjustment coefficient λ.
