中国人民银行长春中心支行历时两年的时间与中科院数学与系统科学研究院合作开发了吉林省经济监测预警系统。2009年初,我们首次运用该系统的计算结果对2009年全年吉林省经济发展趋势和主要经济指标进行了预测。近期,我们将预测的趋势和结果与实际的运行情况进行了比较,整体预测准确率较高,特别是工 Changchun Central Branch of the People’s Bank of China took two years to work with the Institute of Mathematics and Systems Science of the Chinese Academy of Sciences to develop an economic monitoring and early warning system in Jilin Province. In early 2009, for the first time, we used the calculation results of this system to forecast the economic development trends and major economic indicators of Jilin Province in the whole year of 2009. In the near future, we have compared the predicted trends and results with the actual operating conditions, and the overall forecast accuracy is high, especially for workers
