DEA方法很丰富啊，创新点层出不穷。不说别的，就网络DEA方法就有很多进展，完全可以结合不同的背景去应用。

主要其实我也不太懂DEA 要写这个论文才知道这个的 什么学科的会比较知道这个？ 你对这个了解吗？我看银行效率大家都用CCR 超效率DEA 三阶段DEA什么的。。。。

1. 两阶段数据包络分析基本上是现在比较标配的做法了。当然比较牛的，还处于测试阶段的是，第一阶段采用数据包络分析算法，第二阶段采用半参或无参的方式跑回归。这个是两阶段数据包络分析方法上面的创新。

2. 数据包络分析本身不是计量经济学的方法，所以无法进行统计学推论。此外，最基本的一个假设是数据内绝无误差，其抽样完全随机。显然这个假设在现实数据上是很难实现的。因此，就需要一些新的方法，比如统计学中的自举法，人为的使数据包络分析模型包含随机项，不过这个现在也基本上标配了。

3. 引入负资产也是现在比较热门的研究方向。比如说，包含了银行的风险管理以后怎样来使用数据包络分析 模型。不良贷款显然是一种负资产，或者是说一种损失，但是一般的数据包络分析模型是假设成本和产出都是大于零的，这和现实情况中存在负资产是相悖的。

4.现在的数据包络分析模型会与其他的模型相组合，例如包含一些随机前沿分析的算法在里面，或者是上面提到的网络数据包络分析.

5. 比较精致的做法是：前期对于原始数据进行预处理，对于所需变量进行一定的分析，就是说，每一步都建立在一定的统计学基础上。这是比较地道的做法。

5. 就选题的角度来讲，范围还是很广的，表外项目,银行资产负债管理方法, 银行风险管理方法，银行资产证券化和不良贷款等等, 随便找本关于银行的教课书，每一章基本上都可以是选题。

和楼主同感啊

现在有用三阶段做的了，最好多搜集相关文献，总结下方法
