The study presents the innovative GDP Matrix method created by Dr. Vlad Reznikov for business development and market entry corporate decisions.  When making a decision on market entry based on limiting factors such as the complexity of regulatory policies, estimated marketing costs, preliminary determination of the target consumer base, language barriers, or any other critical factor for the corporation, the proposed method enables the strategic allocation of business efforts toward countries where the profit potential is highest. This method also allows the classification of these countries according to the cost-effectiveness and efficiency of the required efforts. GDP Matrix is a bubble chart designed to elucidate the intricate relationships between GDP, PPP, and population data from the list of pre-sorted countries by categorizing countries into four quadrants—ROCKSTARS, HONEYBEES, MAVERICKS, and UNDERDOGS—the matrix offers strategic insights for global business development planning.
