索洛余值可以直接解释为在完全竞争和规模报酬不变的情况下技术变化的度量。当这些条件不成立时，必须对残差进行适当调整，以便被视为技术变化的正确度量。我们认为，在采掘业中，索洛剩余也受到不可再生资源持续枯竭的影响。因此，我们提供了一个新的分解的索洛剩余的采掘业的储量水平可能会影响开采成本。我们的实证结果说明了在西班牙的煤炭开采的生产力的测量中所发挥的作用，通过消耗的储备。
The Solow Residual has a direct interpretation as a measure of technical change under perfect competition and constant returns to scale. When these conditions do not hold, the residual has to be appropriately adjusted in order to be considered a correct measure of technical change. We argue that in extractive industries the Solow Residual is also affected by the continuous depletion of a non-renewable resource. Therefore, we provide a new decomposition of the Solow Residual for extractive industries in which the level of reserves is likely to affect extraction costs. Our empirical results illustrate the role played by the depletion of reserves in the measurement of productivity of coal mining in Spain.
