摘　　要：使用时变的成本效率前沿模型,研究了我国城市商业银行在2000～2008年间的成本效率演进与趋势。总体判断,我国城商行的成本效率有随时间而提高的趋势,且其特别适用于资产规模小于300亿元的城商行类群,而对资产规模大于300亿元的城商行而言,其成本效率却有随时间而降低的倾向,似乎城市城商行在做大的同时,并未发挥其应有的规模经济优势和成本节约目标,这与监管当局鼓励或推动城商行跨区域经营,乃至"做大做强"的愿景不完全一致。The paper uses time-varying cost efficiency frontier model to study the cost efficiency evolvement and trend of city commercial banks from 2000 to 2008. The cost efficiency of city commercialbanks increases with time, which especially adapts to those banks whose assets are less than 30 billion. Whereas, the cost efficiency of the city commercial banks whose assets are bigger than 30 billion has thetrend to reduce with time. It seems city commercial banks don＇t play the advantages of scale economy and cost reduction when they are bigger. It casts doubt on the efforts of the regulatory authorities to encourageor push city commercial banks to operate in other regions in order to make them bigger and stronger.
