The outbreak of COVID-19 has had an immeasurable impact on the global economy. It damaged parts real economy, but also provided new opportunities for China’s green development. Both system and foreign direct investment (FDI) have important recovery path. Based provincial panel data China from 2007 to 2016, this paper uses a slacks-based measure (SBM) model Malmquist–Luenberger (ML) index total ...

This paper proposes a global cost Malmquist productivity index, new cost Malmquist productivity index, that is circular and that gives a single measure of productivity change. The index is inspired by the global Malmquist productivity index as extended to productivity measurement. Decomposition of the proposed cost Malmquist productivity index is presented. Numerical results are presented for a...

As China’s largest urban agglomeration with rapid growth of economy and population, the development Central Plains Urban Agglomeration (CPUA) has been severely restricted by environmental problems. Thus, green performance CPUA is worth studying. This study used panel data 29 cities in from 2003 to 2018 based on Slacks-based Measure Global Malmquist–Luenberger index measure total factor producti...

In the context of increasingly prominent contradiction between economic development and ecological environment, how to promote green has become core sustainable development. Digital finance is an innovative financial model with a high degree integration digital technology provides new opportunity for achieving Based on identifying mechanisms environmental regulation efficiency, this research us...

The improvement of port cluster eco-efficiency is great significance to constructing a world-class shipping hub and the high-quality development regional economy. This study adopts Super-EBM (Super-efficiency Epsilon-Based Measure) model evaluate Yangtze River Delta in China, GML (Global Malmquist-Luenberger) index, spatial hot spot analysis, gravity center migration model, Theil index are comb...

In order to balance the economic development and ecological impact of tourism, it is essential study tourism eco-efficiency in context sustainable development. This analyzed regional based on panel data 13 cities Beijing–Tianjin–Hebei region using super-SBM DEA model. Then, we driving factors, compared differences, investigated influencing factors by applying global Malmquist–Luenberger (GML) i...

bankruptcy in the same amount of time and history is very rampant and therefore the vision of the future can be prevented. using data envelopment analysis (dea) and malmquist index can precise evaluating of the performances of many different kinds of decision making units (dmu) such as hospitals, universities, business firms, etc. in this paper, we will modify directional distance formulation o...

In this paper, we investigate the use of adaptive extended Luenberger state estimators for general nonlinear and possibly time-varying systems. We identify the connection between the extended Luenberger observer and Grossberg’s additive model for dynamic neural networks. The association between dynamic neural networks and the Luenberger observer leads to an obvious modification on the proposed ...

The Trade Offs approach is an advanced tool for the improvement of the discrimination of Data Envelopment Analysis (DEA) models, Meta Malmquist Index was defined by Maria Portella and et. al (2008). In this paper we compute the Meta Malmquist Index in Trade Offs model in DEA and we compare, obtaining results, of Meta Malmquist Index in different models of DEA, Variable Return to Scale (VRS), Co...

the productivity change of a decision making unit (dmu) between two time periods can be evaluated by the malmquist productivity index. in this study, we propose a method to compute the malmquist productivity index in several time periods (from the first to the last periods) on interval data in data envelopment analysis (dea). then, the obtained malmquist productivity index is compared with malm...
