In this series of two articles devoted to the same research and incorporating a rich factual and statistical material, we analyze the modern condition of the Russian food market, estimate the consequences of its inclusion into the globalization process and attempt to determine its type. Within the first article, we used the certain criteria to choose the chief retail chains, dominating the food retail market of St. Petersburg, a city that rightfully assumes the role of the Russian window into Europe. We also established that this market is not a humongous whole and that, in order to successfully reach our goal and determine its type, it is necessary to start with dividing the market into segments. The next stage of our study included the analysis of the pricing policy implemented by the major retail chains, which allowed us to make some conclusions about the competitive pattern and domination in this market. This second article in the authors' series on the state and prospective development of the food market in St. Petersburg concentrates on solving the problem of objective evaluation of the concentration level within this sector of the city's economy. To accomplish this, the authors have used traditional methods of statistical processing of extensive factual material.
