The paper presents the results of research on differentiation of the ad- vancement level of solutions and logistics management systems based on ICT (Information and Communication Technologies) used in the Polish food industry. The research was conducted in terms of industry, employment size and three market characteristics of the surveyed enterprises: investment level, financial situation and market position. The study used the IAI (Information Advancement Index) synthe- tic indicator and two methods for categorizing its values: uniform across the range of values and based on mean values and standard deviation. The paper also presents the reference of the obtained research results to the productivity paradox of Solow and the results of similar research previously carried out on the level of advance- ment of logistics solutions and systems in the Polish food industry
