摘要：
The concept of returns to scale and scale elasticity has been frequently studied in the framework of data envelopment analysis. Returns to scale is a qualitative characterization to the frontier points of the technology set and its estimation using tools such as data envelopment analysis (DEA) has attracted considerable attention among researchers. In order to quantify this characterization, we can use scale elasticity that is a quantitative measure of response of the outputs to the change of the inputs of the frontier points in a production set. In the current paper, we propose a method to calculate scale elasticity in banking sector when there are non-discretionary and undesirable factors in the process.
