In different markets, there are different market structures that dictate the market power of an individual company, and the price of the product depends on it, or the ability to influence the price. In a perfectly competitive market, due to their characteristics, firms do not influence the price, while in an imperfect market the situation is opposite and depends on the level of power of the firm. The Croatian cement market has been weakening and declining over the years, but it has still managed to maintain a satisfactory level and cover all the needs and desires of the state and the population in general. Despite the disasters that hit the country, war or crisis situations, Croatia was in an excellent position from 2000 to 2008 and achieved above-average good results. A large drop in turnover occurred at the transition from 2015 to 2016 when it fell by 86.34%, but the situation was still relatively good and in 2018 and 2019 a positive trade balance can be seen. There are 6 manufacturers on the Croatian cement market, and the strongest are CEMEX Hrvatska d.d. and NEXE d.d. Homogeneity and similar product prices and a small number of manufacturers are components that indicate a pure oligopoly of the cement market.
