“…Using efficiency to describe life cycle stages has a theoretical basis and research foundation. Not even a single study has shown a direct relationship between the efficiency, decline or rejuvenation of tourist destinations such as tourism and hospitality [53], business management [54], construction [55], energy [56] linked life cycles to efficiency. For instance, Yin et al (2015) proposed a hotel life cycle model measured by the average efficiency change rate (AECR) and average efficiency (AE) [53].…”

The decline is one of the essential issues for developing tourism destinations. The rapid adoption of appropriate policies will enable them to reverse the decline and enter the rejuvenation stage in time. This study advocated establishing an operational evaluation model of tourism efficiency with DEA and the super-SBM model to estimate when China’s mass tourism destinations are in decline and rejuvenation based on the tourism area life cycle (TALC) theory regarding China’s national scenic areas (NSAs) samples. The results show that the development of China’s mass tourism destinations can be divided into three phases, in which there is a clear process of persistent decline and rejuvenation. Different types of NSAs vary in terms of efficiency level and change trends. Human landscape, caves, and wetland and lakes all have distinct phases of persistent decline, but humanistic landscapes show a significant rejuvenation trend. These findings provide an innovative re-interpretation of the TALC model.

The Assessment of Energy Efficiency versus Planning of Rail Freight Traffic: A Case Study on the Example of Poland

The issues addressed by the article concern the assessment of energy efficiency in rail transport, resulting from the proper organization of rail traffic. The problems related to energy consumption and, thus, the negative impact of rail transport on the natural environment are highly significant in terms of the green deal concept, climate change and sustainable development. In this article, energy efficiency is investigated in the context of minimizing the energy consumption necessary to satisfy a specific transport requirement. The essence of this article is to present an approach to energy-efficient planning of rail freight traffic. This article aims to develop a method covers the allocation of railway vehicles dedicated to freight traffic (locomotives and railcars) to perform a defined transport task, taking into account the energy efficiency assessment of the solution, routing the train launched with regard to the accomplishment of the defined transport task on the railway network, and determining the conditions of transport for a defined transport task, taking into account the allocated rolling stock (locomotives and railcars) and the route. In this article, based on the presented state of knowledge, a decision-making model has been proposed, including the model’s parameters, the values being searched for, indicators for assessing the quality of the solution, as well as the limitations and boundary conditions of the problem. The function of minimizing the energy consumption necessary to transport a shipment within the railway network (determining the energy efficiency of the proposed solution) has been proposed as the criterion. In addition, a description of the proprietary method of selecting rolling stock for accomplishing tasks, based on the assessment of the energy efficiency of the solution and a case study illustrating the operation of the method on the example of the area of Poland, has been presented.

“…Regarding the transition of the entire coal industrial chain, studies have been conducted to assess the energy efficiency and carbon emissions efficiency of coal throughout its life cycle, from its upstream suppliers to the final consumers (Wang et al, 2019b;Wang et al, 2021a;Sun et al, 2022). These studies provide policy implications for achieving clean and efficient coal production and utilization.…”

In order to achieve China’s ambitious carbon neutrality target, coal industry should play a key role in mitigating its carbon emission and ensuring energy supply. Therefore, it is urgent for this coal industry to realize its transition toward low carbon development. This study investigates the status and policy options of China’s coal industry by considering the entire coal industrial chain, covering coal production, delivery, and consumption so that key challenges involving clean and efficient utilization and stable coal supply can be identified. Further, policy recommendations for the transition of this coal industrial chain toward low carbon development are proposed, including the implementation of appropriate national policies, research and development (R&D) efforts, the application of economic instruments and capacity building activities.
