我们提出了一个利润率（收入与费用的比率）变化指数，它可以应用于面板数据来衡量生产率的增长，并适合于生产者希望同时最大化收入和最小化费用的情况。为了识别利润率变动指标变动的驱动因素，我们将指标分解为利润率效率变动和利润率边界变动。我们还提出了一个替代分解的利润率变化指数，这是产品的Malmquist投入导向的生产率指数和分配Malmquist生产率指数。我们证明了日本银行数据集的方法。
We propose a profit ratio (the ratio of revenue to expenses) change index, which can be applied to panel data to measure productivity growth and suitable for situations when producers desire to maximize revenue and minimize expenses simultaneously. To identify the drivers of changes in a profit ratio change index, we decompose the index into profit ratio efficiency change and change of profit ratio boundary. We also propose an alternative decomposition of the profit ratio change index, which is the product of the Malmquist input-oriented productivity index and an allocation Malmquist productivity index. We demonstrate the method on a Japanese banking data set.
