不同条件下固定资产投资函数模型研究

A Study of the Function Model of Fixed Assets Investment in Different Conditions

投资函数模型是对投资行为的描述,也是对影响投资规模因素的分析。对投资函数的研究,实质是对投资规模制约方程的研究,也就是研究如何确定适度的投资规模。而投资规模的大小、投资规模是否适度,又直接决定了投资规模效益的高低。投资与经济增长之间相互依存、相互制约的关系也表明,投资规模是否合理、适度,是影响经济稳定运行的一个重要因素。因此,研究影响投资规模的诸因素,合理、适度确定不同条件下固定资产投资函数模型具有重大的理论意义和实践意义。

Investment function model is a kind of description of the investment behavior and also is the analysis of the factors affecting the investment scale. The investment scale is the decisive factor affecting the returns of the investment scale. The relationship of the interdependence and interrestriction indicates that the extent of the investment scale is the key factor affecting the stable working of the economy. Therefore there is a significant meaning both in theory and in practice for studying the factors affecting the investment scale, and rationally and moderately establish the investment function model in different circumstances.
