Measuring the Efficiency of Market Surveillance and Inspection Activities with Data Envelopment Analysis

In this study, it is aimed to reveal the technical efficiency of market surveillance and inspection activities carried out in 81 provincial directorates that constitute the provincial organization of the Ministry of Industry and Technology. Data envelopment analysis (DEA) was used in the study. For the measurement of efficiency with DEA, first of all, input and output sets were determined and a research model was constructed. Accordingly, the number of auditors working in provincial directorates, the number of vehicles allocated to the provinces for inspections and the amount of budget used for inspection activities constitute inputs. The total number of inspections carried out in the provinces in 2021, the number of products sampled for testing and the amount of administrative fines are the outputs of the model. Inter-provincial comparisons were made according to the efficiency scores obtained with the DEA model, which was designed as output-oriented. According to the results of DEA analysis modeled according to three different output combinations, the provinces that are efficient in all three models are Adıyaman, Ankara, Düzce and Kocaeli. Despite having the highest input values, Istanbul cannot reach sufficient efficiency scores in all three models. It is also noteworthy that Adana, Aksaray, Tokat and Trabzon provinces have low efficiency scores when the development level and industrial infrastructure of the city they are located in are taken into account, despite having a high number of auditors and inspection vehicles.
