But how did invest promote the national economics structure to change? How to ascertain the suitable investment scale? How to enhance the investment benefit? What measure should be adopted in future to improve the investment condition? These questions are the hotspots and the basic problem.This paper has use cointegration theory, error correction model, Granger representation theorem, optimal control model, and some software such as MATLAB ,to build some mathematical models, which calculated and analyzed the series of the comprehensive statistical date about SHANDDONG province, to judge the relationships between the investment and the national economic development and to analyze how did the investment promoted the national economics. This paper includes not only the quantity analyses but also the quality analyses. By the mathematics model we analyzes the investment itself and its effect on the development of economics.Investment is main motive force impetus, we should bring the drawing function into full play, improve the quality of investment and promotethe investment structure to be more optimal and make the whole society economic to have rapid progress.In part 1 we explain the status and function of investment in economics and analyzes the necessary of investment research.
