人均GDP是经济学中衡量人均产出的一个有效统计量,它可以在很大程度上度量社会中居民福利状况,能够指导政府部门做出一系列经济决策。本文基于灰色系统理论,根据2000~2019年浙江省人均GDP数据建立GM(1,1)模型与GM(2,1)模型,结果显示模型精度良好。根据建立的模型对浙江省2020~2025年人均GDP进行预测,为浙江省制定经济政策提供理论依据。

Per capita GDP is an effective statistic to measure per capita output in economics. It can measure the welfare status of residents in society to a large extent, and can guide government departments to make a series of economic decisions.

According to the established model, the per capita GDP of Zhejiang Province in 2020~2025 is predicted, which provides a theoretical basis for formulating economic policies in Zhejiang Province.
