Despite the fact that global competition is crucial for modern markets, a smali amount of microeconomic research has been done so far on this subject. This paper is an attempt to appraise the specificity of global competition on the car market in the US. In the first part of the paper, the concept of competitiveness of global enterprises as developed by Porter, Yip and Polish economists working in the field, is presented. In the second part of the paper the structure of the market, behaviour of producers and effects of global competition, are described. Important part of the paper deals with the identification of characteristics of global competition, such as: dominant role of foreign companies, competition based on cutting costs, and improving quality, elasticity and inventiveness. It should be noted that only successful companies are capable of remaining on the market. In the last part of the paper, recommendations are formulated. These findings can be useful for Polish companies competing on global markets.
