The paper analyzes quantitatively the fixed assets investment and economic increase, and points out the possibility and imperativeness of the investment increase in Jiangxi province, according to the four indexes of fixed assets rate, investment effect coefficient, investment increase coefficient and investment elasticity coefficient.
This paper readjusts the original data with constant prices,forecasts GDP growth rate in Guizhou for the period of the Eleventh Five-year Plan using the CobDouglas production function,and checks the results with investment effect coefficient. The conclusion is that to facilitate the sustained,rapid and stable economic growth in Guizhou during the period,appropriate scale of fixed asset investment is necessary,and ensuring a total fixed asset investment of around 770 billion yuan is justified.
In light of the concept from engineering economics, the initial investments on different gas stations have been calculated by use of the investment effect coefficient, and meanwhile their different economic efficiency analysis has also been discussed taking use of the annual-cost method.
and (3) when the effect coefficients of investment of agriculture, forestry and husbandry are 3.15, 12.08 and 16.23 respectively, indicating that the production of the small watershed firstly be husbandry, and secondly forestry.
According to estimation, the economic benefit is very obvious, in general, the ratio of cost to profit is between 1000% and 3700% , coefficent of effectiveness of the investment is 0.68-2.20, annual productivity per capita is more than 8000 yuan .
In this paper,the author presented a simple and practical method for calculation of Dynamic - Investment Benefit Cofficient on the base of economic benefit and time - lag result , and then proved its validity and relevant properties and conclusion.
