The healthcare system utilises parameters like quality, efficiency, and equality (availability), creating a flexible system in which one parameter reacts to another to a certain extent. This research reacts to these facts, often discussed by experts as well as the general public. It aims to determine the relationship between technical efficiency and quality of hospital care in the context of the federal states of Germany and approximate the influence of selected external factors on their results. The inquiry involves 64 homogeneous production units, i.e., 16 federal states, in 2018–2021. It is therefore a macroeconomic view of the technical efficiency of the units examined and the quality of hospital care within the context of external conditions. Four variables were selected for the evaluation of the DEA input-oriented model (CRS, VRS) – 2 inputs (number of patients per 1 physician, number of patients per 1 nurse) and 2 outputs (number of hospitalised patients per 1 bed, number of days of treatment per 1 bed). The quality of hospital care was analysed based on the results of the nationwide survey of satisfaction of hospital patients. The following factors were selected to investigate the influence of the factors on the results of technical efficiency and quality: number of public hospitals, number of non-profit hospitals, number of private hospitals, number of persons up to the age of 15, number of persons aged over 65. The results showed that the relationship between technical efficiency and quality is inverse in most DMUs. Different results were observed in the city states of Berlin, Bremen, and Hamburg. The results of the tobit model showed that 84% of the net technical efficiency of the hospitals depends on the proportion of limit population groups (the age groups 65 + and up to the age of 15) within the population of the state in question. The results of the influence of external factors on patient satisfaction scores can be explained at the rate of 32%. JEL Classification E23, I10, C02

Forestry is the underpinning of economic and environmental civilization for sustainable economic development. Forestry benefits ecosystems and local dwellings; thus, transforming and advancing forest products in a civilized society is critical to building a progressive community. This research aims to analyze the merits of forest products based on static, dynamic, and scale efficiency. It employed the super-efficient data envelopment analysis—Charnes, Cooper and Rhodes, and Malmquist index methods with an enhanced robustness check by applying the Stochastic Frontier Analysis. The results show that, first, from the perspective of static efficiency, the forestry industry’s operating performance is maintained at a relatively high level, with a minimal fluctuation range; however, the scale efficiency is observed at a deficient level. Limited by the scale efficiency results, the aggregate comprehensive technical efficiency was at a low standard. The average total factor productivity of dynamic efficiency for each company reached 1.029, indicating that the resource allocation of listed companies is relatively reasonable, operating efficiency is on the rise, and technical level changes are a substantial source of total factor productivity growth. Furthermore, the super efficiency DEA findings indicated that 11 of the most high-performance companies attained an efficiency value above criterion value one after re-ranking. The comprehensive efficiency value of Sun Paper reached 1.438 in 2019, Sophia 1.393, Hexing Packaging 1.383, Fujian Jinsen 1.326, Bunny 1.271, Meike Home Furnishing 1.235, Jingxing Paper 1.222, Zhongshun Jiezou 1.116, Meiying Sen 1.099, Chenming Paper 1.064, Da Ya Dekor 1.015. Second, the comprehensive efficiency value of Fujian Jinsen’s company has a more significant impact on the overall average efficiency of the forestry listed companies. After excluding Fujian Jinsen, the average comprehensive efficiency of 2018–2019 indicated an upward trend for the listed companies. This study suggests that policymakers should strengthen the forestry industry development plan and policy implementation regulations to focus on the forward-looking and guiding principles of industrial and technological innovation policies.
