The citrus industry is an important fruit industry, with the widest cultivation area and the most crucial economic status in southern China. Evaluating the sustainable development of citrus industry is the basis for accurately grasping the food safety situation and scientifically formulating industrial development policies. This research aims to evaluate the sustainable development policies of citrus industry in 20 citrus-growing cities and states in Sichuan province in China from two dimensions of efficiency and effect. To this end, this study develops a DEA–Malmquist index and DID model using city and state panel data from 2009–2020. The results have the following implications: (1) The low technical efficiency and technological progress index together cause the general inefficiency of citrus production in Sichuan cities and states, and the improper scale of inputs is the main reason for the low technical efficiency. (2) The implementation of sustainable development policies has increased citrus total factor productivity and widened the gap between cities and states in Sichuan. (3) Excessive production factors and financial inputs have hindered the sustainable development of the Sichuan citrus industry.

Evaluation of Sustainable Development Policy of Sichuan Citrus Industry in China Based on DEA–Malmquist Index and DID Model

In recent decades, the Spanish port system has been investing in the development of infrastructures aimed at attracting the cruise market. For this reason, this paper analyses, using a methodology based on data envelopment analysis (DEA), the efficiency of the Spanish port system for the cruise market. Most of the port authorities want to attract and maintain this traffic in their ports, due to the economic impact it has on them. Based on the data provided by Puertos del Estado and the port authorities in their annual reports, such as the number of cruise passengers per port or port authority, the number of stopovers or ships that visit our ports each year, and the infrastructures that have been developed for this market, an efficiency analysis was carried out to draw conclusions at the level of the port system and each port authority in terms of operational efficiency. Focusing the research on Malaga, the current situation was analyzed, as well as the forecasts that resulted from the research for the future development of the port in terms of cruise ships.

Employing DEA for Assessment of Cruise Market: A Case Study in Malaga—Spanish Port

The measurement of power plant efficiency is of great importance for decision makers in order to formulate policies. The purpose of this paper is to analyze the performance of lignite-fired power plants in Greece using data envelopment analysis (DEA) and bootstrap. This research develops DEA-based efficiency metrics based on data from lignite-fired power plants in 2018 and assesses if there are performance disparities between facilities that have been closed or will be closed and plants that are still in operation. The DEA bootstrap results suggest that the power plants are considerably less efficient than what the initial single-DEA efficiency estimates suggested, and additionally, operating lignite-fired power plants are more efficient than those that have already been shut down or are about to be. Furthermore, there is evidence that age may have a detrimental effect on efficiency.

Review of: "Coronary Artery Bypass Graft Surgery Clinical Quality: A Network-DEA approach"

This paper introduces the concept of R4 (road-rail-ro-ro), a concept increasingly used in transport and logistics research circles that defines the modern concept of the transport chain as it passes through the intermodal use of rail, road, and ship via ro-ro. The integration of the new rail-road freight services into the reference supply model allows us to define the supply model for the design scenario on which the evaluation is now focused in terms of service-mode demand shares and in terms of design network flows and performance indicators carried out by demand-supply interaction models applied to all available service-modes. The use of strength-weaknesses-opportunities-threats analysis (SWOT) allows for the identification of some strategies to enhance and improve the current rail and maritime corridors in order to attract more customers using the different services, ultimately triggering the involvement of more actors in generating bigger and better integrated logistic chains using intermodality. The SWOT analysis allows the identification of a series of measures in order to adapt, maintain, enhance or exploit the aspects arising from the expert analysis.
