Each managing subject tries to lower level of risk factors for himself for the purpose of increase of efficiency of activity. One of options of minimization of losses and decrease in action of risk factors is the diversification consisting of distribution of means between various activities so that losses just seeing activity can be compensated by profit on other kind of activity of the managing subject.
In article the diversification of economic activity connected with use by construction company of new production and marketing capabilities for the purpose of increase of efficiency of economic activity is considered.
The decision on diversification as a way of decrease in risk of activity of the enterprise is accepted on the basis of correlation coefficient which shows degree of expressiveness of a tendency to changes of size of one variable at changes another. At value of coefficient of the correlation, equal to zero, lack of communication between variables is observed. If numerical value of coefficient of correlation is equal to unit, variables are connected by direct functional link, that is there are unidirectional changes of variables. At value of coefficient of the correlation, equal the minus to unit, between variables is observed the return functional communication testifying to a raznonapravlennost of change of variables. At value of coefficient of the correlation, equal or close a minus to unit, it is expedient to make the decision on carrying out diversification.
The reasonable model of optimization of a choice of the customer is offered mathematically.

The aim of this work was to conduct monitoring and make a regression model of the microbiological air pollution in Volgograd near highways. The work carried out monitoring of microbial air pollution in the residential district of Volgograd near two major highways - first and second longitudinal lines. On the first phase of research the microbial monitoring of air pollution in the residential district of Volgograd was conducted, depending on the proximity to the highway. Number of microbial cells (MC) was evaluated by sedimentation. The assumption is made about the nature of the regression relationship between microbial air pollution and the distance from the highway. Approximating functions and regression coefficients are constructed for the first portion of the longitudinal line at different levels of traffic road. Function is obtained, which allows to calculate the value of microbial contamination of the air, depending on the distance to the road and number of vehicles. In the case of high levels of the microbiological monitoring of the basin air it’s necessary to carry out measures to reduce microbial contamination of the air, for example, regular watering roads, tree planting, vegetative barriers adsorbing pollutants, chemical treatment of disinfectants. The calculation of microbial contamination of the air near a residential building located at a distance of 10 meters from the highway in the central region of Volgograd is conducted using proposed in function prediction of microbial contamination. The developed technique allows us to make calculations without setting up experiments in a specialized microbiology laboratory.

Leasing is considered as an effective tool capitalization industry's innovative potential. Under capitalization refers to the process of innovation potential effective binding economic resources towards modernization projects and innovatization. In high wear and tear funds of Russian industry and low levels of financial stability of most industrial leasing allows capitalization of their innovative capacity. Mechanisms capitalization innovative capacity of industry achieved on the basis of synergies resulting from the spread of resources and modernization of the industry in improving her competitive relationship. Leasing helps capitalization and innovative potential of the region, providing a concentration of innovation resources in a certain area. Analysis of the development of leasing relations in Russia testifies undeveloped part of a financing tool. To stimulate the development of leasing relations proposed direction of the institutional environment.
