Dynamic problems of estimation of ecological-economic efficiency of regions based on basic models of data envelopment analysis

The paper describes the results of the comparative analysis of the applicability of several methods for solving dynamic DEA-models to the problem of monitoring of the ecological and economic efficiency of economic activities of regional economic systems (on the example of the regions of the Central Federal District, notably Belgorod and Ryazan regions). Methods of forming time series based on point estimates of environmental and economic efficiency, the Malkmquist method and the window method are considered. The results obtained for different window widths are analyzed for stability and adequacy. A comparison of the obtained results allows us to conclude that the window method is uniquely preferable for solving problems of monitoring the ecological and economic efficiency of regions not only from a computational but also from a substantive point of view. Unlike in case of Malkmquist method, system dynamics are more evident, and conclusions can be more easily drawn about the overall direction of the process. Data and graphs used in the comparison are also provided.
