一般来说，实证研究使用对偶理论和成本函数估计或非参数估计方法来评估金融服务业的效率。本研究的目的是估计农业银行业务的范围经济和规模经济。这将通过估计间接多产品成本函数来完成。与之前的金融服务业效率研究相比，本研究的独特之处在于对产出进行了分类，以便可以评估农业贷款。此外，还通过施加曲率特性来估计归一化二次成本函数。克拉克回顾了十三项衡量商业银行、信用合作社以及储蓄贷款协会范围经济和规模经济的研究。他发现他们提供了四个广泛的结论：（a）总体规模经济存在于低投入水平，（b）不存在范围经济的一致证据，（c）存在一些成本互补性的证据，以及（d）金融机构的结果似乎是稳健的。
Generally, empirical studies have used either duality theory with the estimation of cost functions or nonparametric estimation methods to assess efficiency in the financial services industry. The purpose of the present study is to estimate economies of scope and scale in agricultural banking. This will be accomplished through estimation of an indirect multi-product cost function. The uniqueness of this study, when compared to previous studies of efficiency of the financial services industry, is the disaggregation of the outputs so that agricultural lending can be evaluated. In addition, a normalized quadratic cost function is estimated with curvature properties imposed. Clark reviewed thirteen studies that measured economies of scope and scale for commercial banks, credit unions, and savings and loan associations. He found that they offered four broad conclusions: (a) overall economies of scale exist at low levels of input, (b) no consistent evid nce of economies of scope exists, (c) some evidence of cost complementarities exists, and (d) the results seem to be robust among financial institutions.
