This paper investigated the development of hospital cost efficiency and productivity in Finland in 1988-1994 using a comparative application of parametric and non-parametric panel models. Stochastic cost frontier models with a time-varying inefficiency component were used as parametric methods. As non-parametric methods various DEA models were employed to calculate efficiency scores and the Malmquist productivity index. The results revealed a 3-5% annual average increase in productivity, half of which was due to improvement in cost efficiency and half due to technological change. The results by parametric and non-parametric methods compared well with respect to individual efficiency scores, time-varying efficiency and technological change. The state subsidy reform of 1993 did not seem to have any observable effects on the hospital efficiency.
本文运用参数和非参数面板模型的比较应用，研究了1988 - 1994年芬兰医院成本效率和生产率的发展情况。具有时变无效率成分的随机成本前沿模型被用作参数方法。作为非参数方法，采用了各种数据包络分析（DEA）模型来计算效率得分和马尔姆奎斯特生产率指数。结果显示生产率年均增长3 - 5%，其中一半归因于成本效率的提高，另一半归因于技术变革。参数方法和非参数方法所得结果在个体效率得分、时变效率和技术变革方面比较吻合。1993年的国家补贴改革似乎对医院效率没有任何明显影响。
