The study aims to examine the financial efficiency of the textile and clothing industries in Portugal using official statistical data. The main objective is to assess the relationship between spending on research and development and return on assets. The study analyzes the performance of various subsectors of the textile and clothing industries, presenting the relationship between investments in research and development and the operating return on assets over various economic periods. The study adopted data envelopment analysis, classifying decision-making units based on average efficiency levels. The results highlight sectors of manufacture of textiles for technical and industrial use, manufacture of other textiles, production of outerwear, and manufacture of workwear as the most efficient. In contrast, sectors of manufacture of clothing and accessories, manufacture of knitwear, and leather clothing show lower levels of efficiency. From 2003 to 2022, the textile industry exhibited the highest levels of financial efficiency, with an above-average ratio between spending on research and development and return on assets. However, sectors of knitwear manufacturing and textile finishing have maintained a more or less constant level of financial efficiency. The analysis highlights the need for targeted interventions to increase the financial efficiency of different subsectors within the textile and clothing industries. It is evident that there are varying levels of financial efficiency across these sectors, and the need for benchmarking periods can help identify areas for improvement and set achievable goals.

The efficient allocation of public financial resources to energy consumption in Portuguese municipalities is one of the most discussed topics in public finance, given the growing relevance of sustainability and energy efficiency. The study analyzes how public spending affects energy efficiency through a combination of data analysis and hypotheses testing to assess the relationship between public spending and energy consumption. The methodology includes DEA analysis of the financial data and energy consumption of the municipalities, as well as the definition of hypotheses to determine the possible correlations between investment and efficiency. The results suggest that, in general, municipalities with higher levels of public spending have lower levels of energy efficiency. Meanwhile, municipalities with smaller budgets and fewer resources tend to be more efficient. The DEA analysis of the data suggests that energy efficiency is not directly related to the size and/or economic aptitude of municipalities but rather to their ability to adopt new technologies and more efficient budgetary and financial management practices. The hypotheses tested show varying levels of efficiency in public spending in relation to energy consumption. The study also concludes that public policies should focus on technological innovation and benchmarking to improve energy efficiency. The analysis suggests that collaboration between municipalities and the adoption of best practices are essential to tackle regional disparities and promote energy sustainability.
