Abstract Eco-efficiency, especially the total-factor eco-efficiency, measured by DEA models considering undesirable outputs, has been a popular instrument to evaluate sustainable development in recent years. However, pursues not only high eco-efficiency which ensures that utilization of natural resource and environment is way, but also good effectiveness right direction. In this paper, firstly,...

The influence of land granting on green total factor productivity (GTFP) and its mechanisms remain under-explored. Based dynamic spatial panel data 30 provincial administrative regions in China from 2007 to 2017, this study attempts establish the framework a transmission mechanism among granting, manufacturing agglomeration technological innovation, productivity, measures their interactions by ...

The Malmquist index (MI) has demonstrated its usefulness in comparing the performances of Decision Making Units (DMUs) performances. global MI (GMI) been suggested as a means to overcome three drawbacks MI: non-circularity, disparate measurements, and infeasibility. Recently, it appeared that can also be used compare groups DMUs. While this new function increased usefulness, presents same MI. I...

the performance of a supply chain can be evaluated in either a cross-sectional or a time series manner, and data envelopment analysis is a useful method for both types of evaluation. in this paper we develop an index and indicator of productivity change that can be used with radial and non-radial models for supply chain malmquist index. the supply chain malmquist productivity index (scmpi) can ...

In this paper, methods are proposed to design Luenberger type fulland reduced-order observers for rectangular descriptor systems with unknown inputs. These methods are based on the effect of preand post-multiplicative operation of a linear transformation, derived here by means of simple matrix theory. Sufficient conditions for the existence of observers are given and proved. Numerical examples ...

A modi"ed stochastic Luenberger observer (MSLO) structure is proposed to recover the optimal performance of the coventional SLO for obtaining full-state estimates in linear discrete-time stochastic systems. The optimal MSLO (OMSLO) which gives the MMSE estimates is derived by using the general two-stage Kalman "lter. A reduced-order form of the OMSLO is also proposed for systems having singular...

In this research we employ data envelopment analysis (DEA) to measure the Malmquist productivity of semiconductor packaging and testing firms in Taiwan from 2000 to 2003. Malmquist productivity has three components: the measurement of technical change, the measurement of the frontier forward shift, and the measurement of the frontier backward shift of a company over two consecutive periods. Thi...

Data envelopment analysis (DEA) models can calculate the Malmquist Productivity Index (MPI). Classic Malmquist Productivity Index shows regress and progress of a DMU in different periods with efficiency and technology variations without considering the present value of money. This issue is of major importance since while a currency of in previous year is not equal to that of now this would yiel...
