摘要 从理论角度来看,规模收益是传统DEA模型的一个相关替代模型,用于在全球规模收益假设(例如严格增加或严格减少规模收益)下估计生产技术。然而,从方法论和经验的角度来看,剩下的问题是 的估计。该贡献提出了一种有效的方法来估计基于拟合优度策略的最佳值。首先提出了一种使用网格搜索的全局方法。其次,对于广义的 FDH 技术,开发了最小外推原理来直接估计线性程序的最佳回报。对 1987 年至 2012 年期间 63 个美国行业的说明显示了我们方法的相关性。
Abstract From a theoretical point of view, -returns to scale is a relevant alternative to traditional DEA models for estimating production technologies under global returns to scale assumptions such as strictly increasing or strictly decreasing returns to scale. However, from a methodological and empirical point of view, a remaining question is the estimation of . This contribution proposes an effective methodology to estimate an optimal value of based upon a goodness-of-fit strategy. A global method using a grid search is presented first. Second, for generalised FDH technologies, a minimum extrapolation principle is developed to estimate directly the optimal -returns from a linear program. An illustration on 63 US industries over the period 1987–2012 shows the relevancy of our approach.
