Labor productivity can be attributed to the soft methods of enterprise management. We consider a model for increasing GDP with limited resources. The task of increasing analysis and increasing labor productivity is considered. We analyze the current state of labor productivity at 148,000 Russian enterprises. The parameters of the dependence of labor productivity of industrial organizations on revenue are revealed. Regression dependences of labor productivity on revenue are considered in the form of power, quadratic, and linear trend. Power law parameters can be helpful for researchers of Cobb-Douglas functions.
