- Description:
- As the developing speed of the country industry economy depends to a large extent on the developing speed of the whole country economy, .it is the key of success of the country economy planning that how to bring the region superiority into full play, and that which of priority sectors in industry should be developed under the circumstances of limited funds, resources and sources of energy. For this reason, it is difficult to get a united opinion when discussing that which is priority sector in undertaking a country economy planning.A system dynamics model (SD2 model) suggested in this article is actually one of the model group of system dynamics. The model can be used to evaluate those priority sectors dynamically through being introduced the method of multiobjective decision analysis. In the article, the writer also introduce a simple a simple method of preference ranking about equality or inequality weight targeted values in a time period of time, so the scientific quantitative basis can be supplied for working out the country economy planning.There are several characteristics of SD2 model. It can be used to dialogue between person and computer conveniently, to compare and analyse multi-plannings, to give the user dynamic economy indicators and benefits indicators, e.g. fixed assets, labors, rate of profits and taxes to funds,etc. If cutting out the rate of output values of sectors in the evaluating indicators, we can obtain an evaluating indicator for general economy benefits.The simulation results of the SD2 model have supplied an important reference for working out a county economy planning used in practice effectively. Of course, this model can still be used for the same questions in other sectors or in larger regions.
