Industry 4.0 Technologies in SMEs and Differences According to Company Size and Sector of the Company: The Case of the Czechia

The article focuses on adoption of Industry 4.0 technologies in Czechia's small and medium-sized enterprises (SMEs). It examines how enterprise size and sector affect the level of implementation of these technologies. The main objective is to observe the differences in the use of modern technologies in SMEs based on enterprise size and the sector in which they operate and to identify the main barriers to their implementation. The research was conducted online between October 2023 and January 2024, involving 240 respondents from various sectors. The statistical analysis included a non-parametric multivariate analysis of variance (PERMANOVA), the Kruskal-Wallis test, ordinal logistic regression and the Dunn test. The results show that larger enterprises tend to implement modern technologies more frequently than smaller ones, the main barrier being a lack of financial resources. It was also found that the sector in which a company operates does not have a statistically significant impact on the level of implementation of Industry 4.0, but it is a specific predictor of implementing specific technologies in some cases. These findings highlight the need for targeted support to smaller enterprises in education, skill development and securing financial resources for technology investments. Implications for Central European audience: The theoretical contribution of the article lies in expanding knowledge about the factors influencing adoption of Industry 4.0 technologies in small and medium-sized enterprises. The practical application focuses on identifying barriers that hinder implementation of these technologies and providing recommendations for improving support to small and medium-sized enterprises in adopting modern technologies, mainly through education and financial support.
