“…Chung et al [27] first proposed the DDF method to examine environmental efficiency. Relevant studies on assessing environmental performance using the DDF method could be seen in Watanabe & Tanaka [28], Macpherson et al [29], Halkos & Tzeremes [30], Ramli et al [31] and Njuki & Ureta [32]. There are two limitations of the conventional DDF in the literature [33].…”

Abstract:Resource depletion and environmental degradation have become serious challenges for China's sustainable development. This paper constructs indicators to assess China's green economy performance and green productivity growth, in which economic expansion, resource conservation and environmental protection need to be incorporated simultaneously. For this purpose, we combine non-radial directional distance function and meta-frontier Malmquist productivity to develop the indicators. The methodology also allows for the decomposition of driving forces of China's green economy. Moreover, the dataset employed in this paper allows for the evaluation of 275 cities in China during the period 2003-2012. The main findings are as follows. First, most of China's cities did not perform efficiently in terms of the green economy, with an average score of only 0.233. Second, the growth rate of green productivity is slower than real GDP, and the green productivity growth in China is only moderate. Third, innovation is the main driving force of China's green productivity growth, but the central region lags behind when it comes to green innovation. Fourth, artificial local protectionism and transport limitations impede the progress of cities that perform ineffectively in the green economy. Based on our empirical findings, we provide policy implications and suggestions for enhancing China's green economy performance and productivity growth.

Incorporating Material Balance Principle in industrial and agricultural performance measurement systems with pollutant factors has been on the rise in recent years. Many conventional methods of performance measurement have proven incompatible with the material flow conditions. This study will address the issue of eco-efficiency measurement adjusted for pollution, taking into account materials flow conditions and the Material Balance Principle (MBP) requirements, in order to provide 'real' measures of performance that can serve as guides when making policies. We develop a new approach by integrating slacks-based measure to enhance the Malmquist Luenberger Index by a material balance condition that reflects the conservation of matter. This model is compared with a similar model, which incorporates MBP using the trade-off approach to measure productivity and eco-efficiency trends of power plants. Results reveal similar findings for both models substantiating robustness and applicability of the proposed model in this paper.

Gran parte de las estructuras de hormigón armado se han construido en la primera mitad del Siglo XX,por lo que su vida útil se encuentra actualmente en una etapa crítica desde la perspectiva del mantenimiento. Uno de los mecanismos de degradación más frecuentes y costosos en este tipo de infraestructura está asociado con la corrosión del refuerzo inducida por el fenómeno de carbonatación. Bajo este contexto,el objetivo de este artículo fue la formulación de un modelo de toma de decisiones para la planificación de la inspección óptima. Los tiempos de inspección fueron optimizados considerando la incertidumbre inherente al proceso de degradación y una compensación entre los costos de inspección y la capacidad de servicio de la estructura. Se ha elaborado un análisis de eficiencia a través de dos enfoques: el Análisis de Frontera Estocástica y el Análisis de Envolvente Multidireccional. Este análisis proporciona una evaluación que reduce el número de inspección necesarias y el intervalo de tiempo entre inspecciones para proporcionar no solo una solución óptima, sino también más eficiente. Así, el resultado de esta investigación comprende un modelo numérico para la obtención de los tiempos de inspección más adecuados durante la vida útil de la estructura.
