| The control technology applies to the analysis of the investment and delivers relational, it is one extreme research topics in economical fields in the recent years. It is also the extremely complex non-linear problem. In the control process of west regional planning, the industrial development relates the regional economic development in every aspect. It is the important content of the regional development; the regional investment is also the first driving force of the regional economy growth. But industrial investment structure is whether reasonable or not, which influences industry development directly. Therefore, the adjustments on the industrial investment structure and the industrial structure are very significant to the entire regional industry and entire regional economy growth. As the industrial investment structure in the economic policy adjustment and the restriction of the natural factor, causes the industrial investment structure indefinite in addition in the certain degree, and causes the data of certain industry and certain year's investments has undulation. Thus the data of the regularity was weaker, and it increases the difficulty of the traditional method (for example return analytic method) to analyze this question. It also reduces the confidence level of the analysis conclusion. Therefore, the paper solves this problem by gray system theory.First, the paper has carried on the gray connection analysis to the regional industrial economic indicator. The obtained conclusion has applied to economical condition which analyzes the west. It has explored the reason that the development of the western area is not balance. It has formulated the future industrial structure and the industrial investment development plan for the west. Then, the paper has based on thorough research investment question, and has proposed to establishment investment forecast model, namely in the light of the relation of investment and delivery. It has established the forecast model of the investment and has proposed investment forecast method that bases on the gray system theory. These have solved the establishment problem of investment forecast model well. Finally, the paper proved these two methods to be valid by the example. We have carried on the suitable adjustment about industrial investment structure from the analysis result to the western industry west. It will instruct adjustment direction of instructs the existing industrial investment structure by this, and enhance the optimization of the industrial benefit, finally it will promote the economy development of the entire west region. |
