THE PERSONAL SERVICE MARKET: PECULIARITIES OF THE REGIONAL DEVELOPMENT (BY EXAMPLE OF THE KRASNOYARSK REGION MARKET)
Abstract
The dynamics of personal services market development in the Krasnoyarsk Region is notable for lagging behind those of all-Russian ones. Besides, there is a lower growth rate of the personal services volume in 2008. Having sufficiently large potential, the market of personal services can be attractive to average and small-scale businesses. The share of personal services in total amount of paid services testifies to it in 2002. The decision of business and state regulation in the branch of personal services should be based on applied scientific research of the market taking into account current trends, in particular the market fragmentation.
