Secondly, by comparing of return rates of different industries, we can know that the value creation abilities of high-tech industries are higher than the traditional industries.
But with the influence of the natural conditions,industry technological level,demand structure,capital supplies,regional trade,our national industrial policy and so on, the following problems appear in the west of our country,which include the excessive agricultural proportion,lower technical level of manufacturing industry, the prominent delayed development of tertiary industry,and the low speed of industrial structure promotion.
(2) On the level of "industry", these factors such as the industry's technology level, the correlative degree among industries, the industry cluster and the protection of technology property right are crucial to the process of technology spillover on inter-industry.
In order to advance technology,strengthen competitive strength and realize the sustainable development of Inner Mongolia coal's industry,the ecological and cluster transition of technological innovation will be the effective paths.
Problems , such as disperfect policy, irrational structure, confusive market, low-grade technique and low scope benifit of enterprise,were existed in environmental protection industry. To develop environmental protection industry soundly should formulate and perfect environmental protection industrial policy, rationally arrange industrial structure, cultivate and adjust maket,improve the technique level and scope benifit of enterprise in the light of juncture of market economy reform.

Through assessing the water quality of upper reaches of Yangtze River(Sichuan Province)and analyzing the industry density of Sichuan province,a relation of water quality and industry density was found and a math model was established.Deriving the equation and letting the derivation equal to 1,a very important point was gotten.When G ′>141 71×10 4 Yuan/km 2 the water quality will lower down quickly.For protecting the water quality and making economy sustained development at the upper reaches of Yangtze...
