 note = {This workshop is supported by JSPS KAKENHI Grant Number 22310097 under the title “Theory and Applications of Dynamic DEA with Network Structure.”, We propose a dynamic DEA model involving network structure in each period within the framework of a slacks-based measure approach. We have previously published the network SBM (NSBM) and the dynamic SBM (DSBM) models separately. Hence, this article is a composite of these two models. Vertically, we deal with multiple divisions connected by links of network structure within each period and, horizontally, we combine the network structure by means of carry-over activities between two succeeding periods. This model can evaluate (1) the overall efficiency over the entire observed period, (2) dynamic change of period efficiency and (3) dynamic change of divisional efficiency. In addition, we also introduce dynamic Malmquist index by which we can compare divisional performances over time. We applied this model to a dataset of US electric utilities and compared the result with that of DSBM., Workshop 2013 on Dynamic and Network DEA (January 29-30, 2013)},
