and production  in mining industry, and applies LMDI to decompose the factors driving carbon emission, aiming at gaining a full understanding of carbon emission of mining industry and at offering references to make appropriate policies in promoting sustainable development of mining economy. The results indicate that the carbon emission and intensity first rised and then fell with a yearly rising rate of 2.92% and -5.77%. Their decoupling status shows weak decoupling. Coal mining, washing, coking coal and electricity play the key role in carbon emission. Increment of economic output is the key factor driving the carbon emission to rise, while a fall in energy intensity plays a major part in decreasing carbon emission. 

Guizhou province, under the constraints of resources and environment, needs to convert resources advantage into industrial development. The selection of its leading industry is closely related to leaping development. This paper uses demand flexibility, industrial linkage, relative advantages, environmentfriendly basis to set up index system to select Guizhou's leading industries by means of APH. Results show tobacco, coal mining and processing, wine, beverage and refined tea, pharmaceutical manufacturing, transportation equipment, nonferrous metallurgy and processing and industrial mineral products are of industrial advantages and shall be the leading industries. This paper presents suggestions for industrial development.
