| 摘要: |
| 选取广西1990~2005年的地区生产总值、第一产业产值、第二产业产值、第三产业产值、财政收入、社会消费品零售总额、固定资产投资等7个指标16年的数据,利用时序全局主成分分析方法动态描绘广西1990~2005年的经济发展历程。描绘结果显示,1998年以前广西的经济发展速度较慢,1998年以后,广西经济发展有所加快,尤其是2001~2005年经济发展保持持续快速发展的势头。描绘结果与广西经济发展实际情况基本吻合,时序全局主成分分析方法可以综合评价国民经济的发展状况。 |

| Abstract: |
| In this article, the GDP, the total value of the primary industry,the total value of the secondary industry, the total value of the tertiary industry, financial revenue, the total retail sale of consumer goods and the fixed assets investment from 1990 to 2005 are selected. The economic course of Guangxi from 1990 to 2005 dynamically by means of time series analysis and all-around PCA is described. The result is as follows:the rate of Guangxi economic development is slow before 1998 and speed up after 1998.Particularly, the sustained and rapid development economy is kept in 2001~2005. The result has shown that the dynamic track can accord with the fact. Therefore, time series analysis and all around PCA can be used in comprehensive evaluation of the economic development. |
