水利经济系统运行与发展的数理分析模型

Mathematical analysis model for operation and development of water conservancy economic system

针对水利经济系统的运行发展规律,综合考虑资金、劳动力、固定资产折旧、移民及技术创新的影响,采用合理的假设,建立了数理分析模型,得到定量描述劳动增量、资本增量、人均资本增量等系统状态指标运行规律的微分方程组,并对江苏省水利经济的运行状况进行了分析.计算结果显示,江苏省水利经济已从劳动密集型产业转变为资金密集型产业.该结论与实际情况相符.

In consideration of the influences of fund, manpower, fixed assets depreciation, resettlement, and technical innovation, a mathematical model was developed for analysis of the operation and development regularity of water conservancy economic systems based on some reasonable hypotheses. Different equations were obtained, which could quantitatively describe the operational regularity of some systemic state indexes, including labor increment, fund increment, and per capita fund increment. An analysis of the operational situation of Jiangsu water conservancy economy shows that the water conservancy economy of Jiangsu Province has been converted from a laborintensive industry to a fundintensive one, and the conclusion conforms to the reality.
