Resource extraction industry scale change grey forecast and with environmental coordinated development analysis based on Cobb-Douglas function

Twelfth Five-Year Plan clearly raises that: resource-based enterprises should continuously improve the output efficiency, and take into account the impact on the environment, getting low carbon path of economic development. By Cobb-Douglas production function, we use net fixed assets, the annual number of employees, output and other indicators of resource extraction modeling to measure factors of production. found that: α＋β>1 (Expand the scale of production is beneficial to increase the output)。With the gray analysis:Capital is the maximum value of the correlation;While taking advantage of GM (1,1) model of resource mining industry for the next 2 years of data to predict;As the scale advantage in the form of resource extraction must be closely coordinated with the development of environmental responsibility, not the other.
